different routes, and the handheld I pick to watch both tips under the skin is the Suresult L20Pro at {{SRX_PRICE:31250}}: 16\/20 MHz across a 25 mm footprint, depth presets from 10 to 40 mm, Color, Power and PW Doppler, and Needle Enhance with in-plane and out-of-plane guides in the price. In Pavicic&#8217;s 2019 cadaver study a 22G cannula needed 1.50 N to enter a facial or superficial temporal artery against 1.08 N for a 22G needle, and at 27G the difference vanished, 0.78 vs 0.70 N; in Alam&#8217;s 2021 survey of 370 US dermatologists, cannula injections carried 77.1% lower adjusted odds of vascular occlusion. Gauge, entry point and plane decide the rest, and the 2025 Delphi panel makes a vessel map mandatory before filler in the forehead, glabella, temple, nose and pyriform fossa. Below: what the force and placement studies show, the tool and gauge each facial area calls for, what ultrasound shows at a cannula or needle tip, a guided cannula pass step by step, and the five handhelds ranked for the work.<\/p>\n<div class=\"sr-author-meta\"><span><b>Updated<\/b> October 31, 2026<\/span><\/div>\n<section aria-label=\"Reviewed by Suresult clinical authors\" class=\"srx-author-panel sr-author-panel\">\n<p class=\"srx-author-kicker\">Written and clinically reviewed by<\/p>\n<div class=\"srx-author-list\">\n<article class=\"srx-author-card sr-author-card\" data-sr-author=\"fernando-mariz-md\"><span aria-label=\"Verified author\" class=\"srx-verified-badge\"><svg viewBox=\"0 0 16 16\" width=\"16\" height=\"16\" aria-hidden=\"true\" focusable=\"false\"><path d=\"M3.5 8.4l2.9 2.9 6.1-6.6\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"\/><\/svg><\/span><img loading=\"eager\" decoding=\"async\" width=\"72\" height=\"72\" alt=\"Fernando Mariz, MD\" class=\"srx-author-portrait\" src=\"https:\/\/suresultmed.com\/wp-content\/uploads\/fernando-mariz-md-author-avatar.png\"\/><\/p>\n<div>\n<p class=\"srx-author-name\">Fernando Mariz, MD<\/p>\n<p class=\"srx-author-role\">Gynecology, pelvic surgery, women\u2019s health and sonography<\/p>\n<\/div>\n<details class=\"srx-author-details\">\n<summary>About Dr. Mariz<\/summary>\n<p>I\u2019m Dr. Fernando Mariz, a gynecology and pelvic surgery physician practicing in New York City.

Cannula injections carried 77.1% lower adjusted odds of vascular occlusion in Alam&#8217;s 2021 survey, and a vessel map of the track before the pass, with the shaft held in-plane under the probe during it, shows where the tip sits against each vessel.<\/p>\n<p><strong>The Suresult L20Pro ({{SRX_PRICE:31250}}) is the handheld I rank first for filler cannula and needle work, at 89.3\/100.<\/strong> Its 16\/20 MHz band runs from a 10 mm preset for the dermis and superficial fat to a 40 mm preset that reaches the supraperiosteal plane over the zygoma and maxilla, so one probe follows a cannula from the entry point to the deepest filler planes in the face. Needle Enhance and the in-plane and out-of-plane guides keep the shaft and tip on screen, Color, Power and PW Doppler map the vessels on the track, and FaceAtlas AI, with 3 months included, names old filler before the next pass. Five years with the FaceAtlas AI lifetime license, on sale until December 31, 2026, come to {{SRX_TOTAL:P31250+S36383}}.<\/p>\n<p>The Clarius L20 HD3 is second at 69.8, an 8\u201320 MHz linear to 4 cm whose Needle Enhance, PW Doppler and Vessel Depth AI come with the Clarius Essentials membership.<\/p>\n<\/div>\n<\/section>\n<section id=\"comparison\">\n<h2>Five handhelds compared for filler cannula and needle guidance<\/h2>\n<p>The Suresult L20Pro leads the five at 89.3\/100, with Needle Enhance, the in-plane and out-of-plane guides and all three Doppler modes in its price; all five image the face with a linear array and show Color Doppler. For cannula and needle work they part ways on seven points: the tools that keep a shaft and tip visible, the top frequency for the shallow planes, the depth that reaches bone, the Doppler modes that come with the purchase, software that reads old filler and layer depth, the length of clip the records keep, and the five-year cost of the whole kit.<\/p>\n<div class=\"sr-table-wrap sr-comp\" data-sr-primary-buyer-table>\n<table id=\"table-equipment\">\n<caption>Five handheld ultrasounds for filler cannula and needle guidance, ranked;

Pavicic&#8217;s team pushed needles and cannulas into facial and superficial temporal arteries 294 times: a 22G cannula needed 1.50 N against 1.08 N for a 22G needle, a 25G cannula 1.04 N against 0.69 N, and at 27G the two measured 0.78 vs 0.70 N, with no significant difference (Pavicic 2019). Siperstein&#8217;s 2023 bench test of three cannula brands at 22, 25, 27 and 30G found more force for every cannula than for the needle of the same size, and arterial entry took numerous attempts. In practice, Alam&#8217;s 2021 survey of 370 US dermatologists found 77.1% lower adjusted odds of vascular occlusion with a cannula; the signs, the Doppler findings and the first hour of treatment are in the <a href=\"\/vascular-occlusion-filler\/\">vascular occlusion guide<\/a>.<\/p>\n<div class=\"sr-table-wrap sr-comp sr-can-t-force sr-can-stack\">\n<table id=\"table-force\">\n<caption>Force to enter an artery with a cannula and a needle of the same gauge, in cadaver and bench studies.<\/caption>\n<thead>\n<tr>\n<th scope=\"col\">Gauge<\/th>\n<th scope=\"col\">Needle<\/th>\n<th scope=\"col\">Cannula<\/th>\n<th scope=\"col\">Study<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td data-label=\"Gauge\"><b>22G<\/b><\/td>\n<td data-label=\"Needle\">1.08 \u00b1 <span class=\"sr-nw\">0.25 N<\/span><\/td>\n<td data-label=\"Cannula\">1.50 \u00b1 <span class=\"sr-nw\">0.31 N<\/span><\/td>\n<td data-label=\"Study\">Pavicic 2019, 294 penetrations of facial and superficial temporal arteries<\/td>\n<\/tr>\n<tr>\n<td data-label=\"Gauge\"><b>25G<\/b><\/td>\n<td data-label=\"Needle\">0.69 \u00b1 <span class=\"sr-nw\">0.24 N<\/span><\/td>\n<td data-label=\"Cannula\">1.04 \u00b1 <span class=\"sr-nw\">0.36 N<\/span><\/td>\n<td data-label=\"Study\">Pavicic 2019<\/td>\n<\/tr>\n<tr>\n<td data-label=\"Gauge\"><b>27G<\/b><\/td>\n<td data-label=\"Needle\">0.70 \u00b1 <span class=\"sr-nw\">0.29 N<\/span><\/td>\n<td data-label=\"Cannula\">0.78 \u00b1 <span class=\"sr-nw\">0.35 N<\/span>, no significant difference (p = 0.558)<\/td>\n<td data-label=\"Study\">Pavicic 2019<\/td>\n<\/tr>\n<tr>\n<td data-label=\"Gauge\"><b>22 to 30G, three cannula brands<\/b><\/td>\n<td data-label=\"Needle\">Less force at every gauge<\/td>\n<td data-label=\"Cannula\">More force at every gauge; arterial entry took numerous attempts<\/td>\n<td data-label=\"Study\">Siperstein 2023<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p>The hand cannot tell an artery from tissue at the tip. In Tansatit&#8217;s 2017 dissections of 100 arterial segments, a 25G cannula meeting the frontal branch of the superficial temporal artery at a right angle perforated it in specific situations, and the resistance of a fibrous septum in the track feels the same at the cannula tip as the resistance of an artery wall; the authors run the track away from the main artery. Ugradar&#8217;s 2019 study of 20 hemifaces drew the line at 22G: 18G and 22G microcannulas never entered the facial artery, while 23G, 25G and 27G cannulas went in at 0.72\u20130.81, 0.43\u20130.54 and 0.23\u20130.32 kg, less force the finer the cannula. Siperstein ties the outcome to each cannula&#8217;s friction and flexibility as well as its gauge. In the temple, tissue resistance rose with cannula diameter and with depth across 3,664 cadaver insertions from 21G to 27G (Ko 2026), and length caps force: an 18G 70 mm cannula generated at most 32.1 N in the temporal fossa, short of the 40.4 N needed to enter the skull, while a 15 mm length reached 75.3 N (Philipp-Dormston 2018).<\/p>\n<div class=\"sr-table-wrap sr-comp sr-can-t-gauge sr-can-stack\">\n<table id=\"table-gauge\">\n<caption>The narrowest cannula each source recommends, and the basis for it.<\/caption>\n<thead>\n<tr>\n<th scope=\"col\">Source<\/th>\n<th scope=\"col\">Gauge statement<\/th>\n<th scope=\"col\">Basis<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td data-label=\"Source\"><b>Sigrist 2024<\/b><\/td>\n<td data-label=\"Gauge statement\">Blunt cannulas of 25G or larger for the forehead, glabella and temple<\/td>\n<td data-label=\"Basis\">Best-practice paper, upper face<\/td>\n<\/tr>\n<tr>\n<td data-label=\"Source\"><b>Vasconcelos-Berg 2024<\/b><\/td>\n<td data-label=\"Gauge statement\">A blunt 25G or larger cannula is the safest tear trough technique<\/td>\n<td data-label=\"Basis\">Best-practice paper, midface, nose and tear troughs<\/td>\n<\/tr>\n<tr>\n<td data-label=\"Source\"><b>Goodman 2020<\/b><\/td>\n<td data-label=\"Gauge statement\">Cannulas finer than 25G can behave somewhat like needles in piercing vessels<\/td>\n<td data-label=\"Basis\">Consensus on HA embolic visual loss<\/td>\n<\/tr>\n<tr>\n<td data-label=\"Source\"><b>Heydenrych 2021<\/b><\/td>\n<td data-label=\"Gauge statement\">Intravascular placement is possible with a cannula, especially finer than 25G or with fibrosis or skin tethering beneath<\/td>\n<td data-label=\"Basis\">10-point safety plan<\/td>\n<\/tr>\n<tr>\n<td data-label=\"Source\"><b>Bhojani-Lynch 2025<\/b><\/td>\n<td data-label=\"Gauge statement\">25G preferred; 27G not recommended, for the false sense of security it gives<\/td>\n<td data-label=\"Basis\">Expert overview, infraorbital hollows<\/td>\n<\/tr>\n<tr>\n<td data-label=\"Source\"><b>Pavicic 2019<\/b><\/td>\n<td data-label=\"Gauge statement\">A 27G cannula is no safer than a 27G needle<\/td>\n<td data-label=\"Basis\">294 arterial penetrations<\/td>\n<\/tr>\n<tr>\n<td data-label=\"Source\"><b>Hong 2024<\/b><\/td>\n<td data-label=\"Gauge statement\">21\u201323G for deep work near muscle, 25\u201327G for superficial planes; some facial vessels are wide enough to admit a 23G cannula<\/td>\n<td data-label=\"Basis\">Review of vascular complications<\/td>\n<\/tr>\n<tr>\n<td data-label=\"Source\"><b>Bae 2024<\/b><\/td>\n<td data-label=\"Gauge statement\">Most frontal-branch segments of the superficial temporal artery measure below <span class=\"sr-nw\">1 mm<\/span> inside, against <span class=\"sr-nw\">1.27 mm<\/span> across an 18G cannula<\/td>\n<td data-label=\"Basis\">Temple vessel measurements<\/td>\n<\/tr>\n<tr>\n<td data-label=\"Source\"><b>Ugradar 2019<\/b><\/td>\n<td data-label=\"Gauge statement\">Microcannulas finer than 22G entered the facial artery with a low amount of force<\/td>\n<td data-label=\"Basis\">20 hemifaces<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p>The consensus papers favor the cannula region by region. Signorini&#8217;s 2016 global panel held that HA can be placed safely and efficaciously by cannula or needle when used appropriately, asked for caution with needles in the glabella, alar base, nose and temple, and preferred blunt cannulas there. Goodman&#8217;s 2020 visual-loss consensus rated cannulas safer in the brow and in the lateral and anterior cheek, and asked for micro-boluses under 0.1 mL with the instrument run across the main axial vessels rather than along them. Hong and Yi&#8217;s 2026 review gives the needle fast, precise, shallow work and the cannula areas with a dense vascular network, naming the forehead and the nasolabial folds, in exchange for an entry point and a longer procedure; Kazin and Bertucci&#8217;s 2026 review of the temple, nose, lips and jawline weighs the cannula&#8217;s lower occlusion risk against the needle&#8217;s value for precise placement; and Lee&#8217;s 2026 review matches the device to the region, the indication and the operator&#8217;s skill, with ultrasound to confirm the plane. In Nikolis&#8217;s 2024 Safety Task Force of 16 experts from nine countries, 93% used cannulas for some injections and 43% used ultrasound.<\/p>\n<\/section>\n<section id=\"trials\">\n<h2>Filler cannula vs needle in trials: bruising, pain and placement<\/h2>\n<p>Head-to-head trials favor the cannula on bruising and pain in most areas, and the infraorbital hollow is where the results split.

On the forehead bone, Faria&#8217;s 2025 specimens received a 22G 50 mm cannula and a 27G 13 mm needle held at 45\u00b0 bevel down, and both put the filler on the periosteum in every case, while the same needle at 90\u00b0 spread it across several layers; in Pavicic&#8217;s 126 needle injections across the forehead, scalp, zygomatic arch and mandibular angle of seven donors, a 90\u00b0 angle raised the odds of superficial spread tenfold against 10\u00b0 bevel down (OR 10.0). Bone contact holds the tip for the cannula more than for the needle: in van Loghem&#8217;s cadaver series cannula product stayed in the deep layers, while needle product placed on the periosteum tracked back along the needle path into several layers, and an intra-arterial injection occurred with the needle tip in constant contact with the periosteum.

Lee&#8217;s 2019 series scanned 50 patients before dorsal augmentation and found the dorsal nasal artery in the midline in 20%, just under the preperiosteal layer in 8% and subdermal in 14%, and favors a large-diameter cannula laid gently on the periosteum. Cong&#8217;s 2022 study of 79 specimens met a named artery at 1.3% to 11.4% of five midline points, and supports either a deep midline needle or a cannula from a single rhinion entry kept deep. Rosengaus and Nikolis prefer the needle held fully against bone or cartilage; the midface best-practice paper uses a 29G or 31G needle on the periosteum or perichondrium, or a 25G cannula in-plane at 20 MHz (Vasconcelos-Berg 2024). On ultrasound in 20 patients treated through an infratip entry, Jung found the tip 1.9 mm off the nasal bone on average and 0.4 mm at the closest, and Bravo&#8217;s 2024 series of 12 noses ran a 22G 50 mm cannula through a 21G pilot under an 18 MHz probe with no adverse effects at 6 months.<\/p>\n<figure class=\"sr-can-fig sr-can-fig--tall\" data-sr-media=\"reel-255\" data-sr-db-asset=\"instagram-suresult-255\"><a href=\"https:\/\/suresultmed.com\/wp-content\/uploads\/cannula-vs-needle-filler-reel-255-nasal-vessels-color-20mhz.webp\" target=\"_blank\" rel=\"noopener\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/suresultmed.com\/wp-content\/uploads\/cannula-vs-needle-filler-reel-255-nasal-vessels-color-20mhz.webp\" alt=\"Color Doppler at 20 MHz showing nasal vessels with a 2.7 mm caliper on a Suresult 16\/20 MHz probe\" width=\"762\" height=\"1004\"><\/a><figcaption>Nasal vessels on Color Doppler at <span class=\"sr-nw\">20 MHz<\/span> and <span class=\"sr-nw\">30 mm<\/span> depth on a Suresult <span class=\"sr-nw\">16\/20 MHz<\/span> probe, with an on-screen caliper reading of <span class=\"sr-nw\">2.7 mm<\/span>: the map that comes before a cannula enters the nose.<\/figcaption><\/figure>\n<\/section>\n<section id=\"tip\">\n<h2>What ultrasound shows at the filler cannula or needle tip<\/h2>\n<p>Held in-plane, along the long axis of a high-frequency linear probe, a cannula or needle shows as a bright straight line with the tip at its leading end; crossed out-of-plane, the same shaft shows as a single bright dot. The best-practice papers for the upper, middle and lower face guide in-plane, so the whole shaft and tip stay on screen, and turn the probe out-of-plane near a vessel to confirm the tip sits outside it (Sigrist 2024; Vasconcelos-Berg 2024; Vasconcelos-Berg 2025), with 1\u20132 mm between cannula and vessel before injecting (Sigrist 2024). The angle of entry matters most: across 1,500 cadaver clips, visibility fell by 0.18 on the log-odds scale for every degree steeper, a larger effect than tissue, bevel or needle type (Dinges 2023). A 27G needle driven perpendicular to bone in the deep temple stays out of view, so that depot is mapped first and placed against the marks (Sigrist 2024).<\/p>\n<div class=\"sr-table-wrap sr-comp sr-can-t-visibility sr-can-stack\">\n<table id=\"table-visibility\">\n<caption>What sets the visibility of a cannula or needle tip on a linear probe.<\/caption>\n<thead>\n<tr>\n<th scope=\"col\">Factor<\/th>\n<th scope=\"col\">What the screen shows<\/th>\n<th scope=\"col\">Numbers<\/th>\n<th scope=\"col\">Source<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td data-label=\"Factor\"><b>Probe orientation<\/b><\/td>\n<td data-label=\"What the screen shows\">In-plane, the whole shaft as a line with the tip at its end;

A cannula that fails to pierce a thick SMAS feels bone yet leaves the filler above the SMAS, and product also runs back along the shaft (Schelke 2023, two phenomena). An entry placed too high cannot reach the deep midface compartments, and HA placed without guidance can end up inside the SMAS itself (Molinari 2026). Over the convex frontal bone, a cannula tip can turn upward and change plane (Sigrist 2024). Each of these shows on the scan during the pass.<\/p>\n<\/section>\n<section id=\"workflow\">\n<h2>How to run a guided filler cannula pass, step by step<\/h2>\n<p>A guided cannula pass runs in three parts: map the track before the entry, follow the cannula in-plane during the pass, and rescan the deposit and the flow after it. Mapping alone is quick: Teixeira&#8217;s map-first technique took 1 to 3 minutes per session in 503 patients on a 20 MHz handheld and moved the cannula into the plane away from the artery, against 5 to 20 minutes for guidance in real time (Teixeira 2025). Rocha&#8217;s three-step method, a map, guided filling and a perfusion rescan, was described across 480 patients at 18 MHz (Rocha 2022). The general setup for guided injections is in the <a href=\"\/ultrasound-guided-filler-injections\/#workflows\">workflows section of the ultrasound-guided filler injections guide<\/a>; the steps below apply it to a cannula.<\/p>\n<ol class=\"sr-steps\">\n<li><strong>Map the track.<\/strong> Before the entry, scan the whole path the cannula will take in B-mode and Color Doppler, across each vessel with the color box steered along it, and mark every artery the track crosses (Sigrist 2024); the Delphi table above lists the areas where this map is mandatory. Sweep for prior filler in the same pass: FaceAtlas AI Filler Scan names the material among seven and gives its depth and size.<\/li>\n<li><strong>Choose the plane against the map.<\/strong> Where the map shows the artery superficial on the track, run the cannula deeper, and where the artery runs deep, stay more superficial (Teixeira 2025). In the midface, place the entry low enough to reach the deep compartments (Molinari 2026), and keep bone-level depots for the needle, as the area table sets out.<\/li>\n<li><strong>Open the entry.<\/strong> Puncture the skin with a needle the size of the cannula or up to two sizes larger: a 23G introducer to bone for a 25G cannula in the midface (Galadari 2022), a 21G pilot for a 22G cannula in the temple and nose (Desyatnikova 2022; Bravo 2024), and a 23G needle for a 23G temple cannula (Kim JS 2024). Where the SMAS is thick, confirm on the scan that the cannula has passed through it before any product goes in (Schelke 2023, two phenomena).<\/li>\n<li><strong>Advance in-plane.<\/strong> Lay the probe along the shaft so the whole cannula and its tip stay on screen, and keep the probe face level over it, because tilt breaks the needle-beam alignment (Mao 2021). On a Suresult probe, Needle Enhance highlights the shaft and the in-plane guide marks its path.

B-mode shows where the product sits against the plane you planned, and the published series show how closely a guided cannula holds it: all 188 midfaces in the intended deep compartment (Schelke 2023, 188 midfaces) and about 90% at day 14 and day 30 in Calomeni&#8217;s 100 injections. Color Doppler then confirms flow on every vessel mapped before the entry, the last step of Rocha&#8217;s method. Saved with the map, the loop becomes the baseline for the next visit, and FaceAtlas AI keeps it in the client&#8217;s file for a one-click comparison; old product found at a later visit is read in the <a href=\"\/ultrasound-guided-filler-dissolving\/#identify-filler\">filler identification section of the dissolving guide<\/a>.<\/p>\n<\/section>\n<section id=\"frequency\">\n<h2>What frequency shows a filler cannula and the vessels around it<\/h2>\n<p>At least 15 MHz, with 18 to 24 MHz on shallow tracks: a cannula pass needs enough frequency to resolve the shallow vessels and layers and enough depth to reach the plane where the track ends. The 2025 Delphi panel and the WFUMB 2025 position paper set 15 MHz as the minimum for aesthetic scanning, and the published cannula-tip frames read 18, 20 and 24 MHz. Frequency trades against reach: at 20 MHz the image goes about 10 mm deep and at 8 MHz about 50 mm (Lee 2023). Most vessels on a cannula track lie inside those first 10 mm, among them the supratrochlear and supraorbital arteries at 3.34 and 3.54 mm from the skin, the frontal branch of the superficial temporal artery at 2.7 mm, the angular artery at 3.6 mm over the pyriform space and the facial artery at 6.27 mm over the mandibular border and 8.04 mm at the ala;

I scored the handhelds on what a cannula pass asks of a probe: a tip that stays on screen in-plane, enough frequency for the shallow vessels and layers, enough depth for the bone plane, Color, Power and PW Doppler to map the track and confirm flow, software that reads prior filler and the facial layers, records for the rescan, and the five-year total for all of it.

Together they ask what a cannula pass needs from a probe: whether it keeps the tip on screen, resolves the shallow vessels and layers, reaches the bone plane, maps and confirms flow on the track, reads prior filler and the facial layers and keeps the rescan on file, and what the whole kit costs over five years.<\/p>\n<ul class=\"sr-comp\">\n<li>Tip visibility (20): 10 for a mode that brightens the needle, and 10 for a guide the maker names for needle work, whether an in-plane or out-of-plane overlay, a biplane view or a midline marker; each at half when a paid plan carries it.<\/li>\n<li>Superficial detail (20): the top linear frequency, scored 20 \u00d7 (MHz \u2212 10) \u00f7 14 and held between 0 and 20: 20 at <span class=\"sr-nw\">24 MHz<\/span>, 14.29 at <span class=\"sr-nw\">20 MHz<\/span> and 2.86 at <span class=\"sr-nw\">12 MHz<\/span>.<\/li>\n<li>Depth reach (10): 10 \u00d7 (maximum image depth in mm \u2212 20) \u00f7 20, held between 0 and 10, so <span class=\"sr-nw\">40 mm<\/span> or more scores the full 10 and <span class=\"sr-nw\">25 mm<\/span> scores 2.5.<\/li>\n<li>Doppler (20): Color 7, Power 7 and PW 6; a mode sold with the handheld earns its full weight, and a mode behind a paid plan half.<\/li>\n<li>Filler software (10): 4 for naming the filler material, 3 for a facial map of injection points or vessels and 3 for layer measurement, halved when a paid plan carries the tool. The <span class=\"sr-nw\">3 months<\/span> of FaceAtlas AI on the Pro probes count as included, and so does a rival tool sold with no tier named.<\/li>\n<li>Records (5): 2 for <span class=\"sr-nw\">60 seconds<\/span> of cine or more, in a figure the maker gives for this exact model; 1 for storage on the device or in the app with DICOM export; 2 for a visit report or a side-by-side comparison, credited in full whichever plan carries them.<\/li>\n<li>Five-year cost (15): 15 \u00d7 the lowest five-year total among the scored models \u00f7 this model&#8217;s total.

The Suresult card leads with the L20Pro because a cannula list spans the shallow vessels and the bone plane, and the L20Pro covers both at 16\/20 MHz on 256 elements, with a 4-hour battery and FaceAtlas AI for the first 3 months.<\/p>\n<p>Six reruns test the order: dropping the software credit (79.3 against 65.3 for the Clarius L20 HD3), dropping cost (79.3 against 63.8), dropping depth (79.3 against 59.8), scoring the Suresult card on the L24Pro (86.6) or on the L14Pro (81.3), and counting every rival needle tool and Doppler mode as included (89.3 against 77.8). Each keeps Suresult first and the Clarius L20 HD3 second. Under the combination least favorable to the L20Pro, with FaceAtlas AI at half credit, map credit only for a vessel map and every rival needle tool and Doppler mode counted as included, it still leads, 82.8 to 77.8. The middle places move in two runs: without cost, the GE Vscan Air SL and the Butterfly iQ3 tie at 38.9, and with rival needle tools and Doppler counted as included, the Butterfly iQ3 rises to third at 62.6.

Every rival figure was read from the maker&#8217;s US pages or the PartsSource listing on October 29 and 30, 2026, and every Suresult figure from its product pages.<\/p>\n<\/section>\n<section id=\"faq\">\n<h2>Filler cannula and needle questions<\/h2>\n<div class=\"sr-faq\">\n<details>\n<summary>Is a filler cannula safer than a needle?<\/summary>\n<p>At 22G and 25G, yes on the bench: a 22G cannula needed 1.50 N to enter a facial or superficial temporal artery against 1.08 N for a 22G needle, and 1.04 N against 0.69 N at 25G, while at 27G the two showed no significant difference, 0.78 vs 0.70 N (Pavicic 2019). Across 370 US dermatologists surveyed by Alam in 2021, cannula use carried 77.1% lower adjusted odds of vascular occlusion. The consensus papers set the line at 25G or larger, and a scan of the track shows where the artery runs before the entry; the signs and first steps after an occlusion are in the <a href=\"\/vascular-occlusion-filler\/\">vascular occlusion guide<\/a>.<\/p>\n<\/details>\n<details>\n<summary>Can a filler cannula enter an artery?<\/summary>\n<p>Yes, and the finer the cannula, the easier it goes in. In Ugradar&#8217;s 2019 study of 20 hemifaces, 18G and 22G microcannulas never entered the facial artery, while 23G, 25G and 27G cannulas did, at less force the finer they were. Siperstein&#8217;s 2023 bench test of three brands at 22 to 30G found every cannula needed more force than the matching needle, with arterial entry taking numerous attempts, and Tansatit&#8217;s 2017 dissections showed a 25G cannula perforating the frontal branch of the superficial temporal artery in specific situations, when it met the vessel at a right angle. A fibrous septum and an artery wall feel the same at the cannula tip, so the scan, not the hand, shows where the artery runs.<\/p>\n<\/details>\n<details>\n<summary>Which facial areas carry the most filler risk, and where is a filler cannula preferred?<\/summary>\n<p>The glabella, alar base, nose and temple: Signorini&#8217;s 2016 global panel names them as areas associated with higher risks of vascular complications and prefers blunt cannulas there. The 2025 Delphi panel lists the forehead, glabella, temple, nose and pyriform fossa as the areas where a vessel map before filler is mandatory, and the area table above gives the entry, plane and gauge for each.<\/p>\n<\/details>\n<details>\n<summary>What gauge filler cannula should you use?<\/summary>\n<p>25G or larger for most of the face. The upper-face and midface best-practice papers recommend blunt cannulas of 25G or larger for the forehead, glabella, temple and tear trough (Sigrist 2024; Vasconcelos-Berg 2024); Goodman&#8217;s 2020 consensus puts cannulas finer than 25G closer to needles in how they pierce vessels; and a 27G cannula enters an artery with about the force of a 27G needle (Pavicic 2019). Hong&#8217;s 2024 review uses 21\u201323G for deep work near muscle and 25\u201327G for superficial planes. In the published techniques, a 22G cannula runs the temple and the jawline, a 25G the tear trough and the marionette lines, and either size the cheek, forehead, nose and nasolabial fold.<\/p>\n<\/details>\n<details>\n<summary>What needle size opens the entry for a filler cannula?<\/summary>\n<p>In the published pairs, the entry needle matches the cannula or runs up to two sizes larger: a 23G introducer taken to bone for a 25G 38 mm cannula in the cheek (Galadari 2022), a 21G pilot for a 22G cannula in the temple and nose (Desyatnikova 2022; Bravo 2024), a 23G needle for a 23G temple cannula (Kim JS 2024), and a needle pilot for a 21G or 23G cannula in the midcheek groove (Hong 2026). For the tear trough tangents, Wilde&#8217;s 2023 series punctured the skin with a 25G needle at 45\u00b0.<\/p>\n<\/details>\n<details>\n<summary>Which filler cannula size suits the cheeks?<\/summary>\n<p>A 22G or 25G cannula into the deep cheek fat. Schelke&#8217;s 2023 ultrasound-assisted series placed product with a 22G cannula in the intended deep midface compartment in all 188 midfaces; Galadari&#8217;s 2022 technique takes a 25G 38 mm cannula through a 23G introducer opened to bone at 90\u00b0; and Jones&#8217;s 2021 trial used a 25G 1.5-inch cannula with an optional 25G 1-inch needle depot on bone at the zygomaticomalar junction. Surek&#8217;s 2015 ports sit 1.5 cm inferolateral to the lateral canthus and 1.5 cm inferolateral to the alar base, into the deep cheek fat, the prezygomatic space and the SOOF.<\/p>\n<\/details>\n<details>\n<summary>Which filler cannula suits the tear trough?<\/summary>\n<p>A 25G cannula about 50 mm long, from a lateral entry. Bernardini&#8217;s 2025 series ran a 25G 50 mm cannula from a lateral entry to a plane deep to the orbicularis oculi in all 246 tear troughs; Bhojani-Lynch&#8217;s 2025 overview prefers 25G and advises against 27G for the false sense of security it gives; and Wilde&#8217;s 2023 cannula series of 1,452 tear trough applications in 583 patients recorded bruising in 4.3% and swelling in 10%. The area table gives the entry point and the volume per eye.<\/p>\n<\/details>\n<details>\n<summary>Is a filler cannula better for cheek filler?<\/summary>\n<p>For bruising and pain, the trial data favor it. In Jones&#8217;s 2021 randomized split-face cheek trial of 60 subjects, pain scored 2.3 on the cannula side against 3.1 on the needle side, and bruising on that side alone ran 8.3% against 20.0%. Goodman&#8217;s 2020 consensus rates cannulas safer in the lateral and anterior cheek. The cheek techniques pair the two: the cannula through the deep fat compartments, and a needle for a depot on bone at the zygomaticomalar junction.<\/p>\n<\/details>\n<details>\n<summary>Does a filler cannula hurt less than a needle?<\/summary>\n<p>In the folds and cheeks, yes: the cannula side hurt less in Hexsel&#8217;s 2012 split-face nasolabial fold trial of 25 participants (P = 0.03), pain scored 2.3 against 3.1 in Jones&#8217;s 2021 split-face cheek trial of 60 subjects, and Fulton&#8217;s 95 patients scored their pain at 3 with a cannula against 6 with a needle, with the same aesthetic improvement.<\/p>\n<\/details>\n<details>\n<summary>What is the difference between a filler cannula and a needle?<\/summary>\n<p>A needle has a sharp bevel, with its opening about 1 mm from the tip (Kim JS 2024); a filler cannula has a blunt, closed tip with its opening on the side, set back from the tip (Sigrist 2024), and enters through a puncture made first with a needle. Filler needles in the cited protocols run about 13 mm, while cannulas run 30 to 70 mm, so one entry reaches a whole track. Hong and Yi&#8217;s 2026 review gives the needle fast, precise, shallow work and the cannula the areas with a dense vascular network, in return for an entry point and a longer procedure.<\/p>\n<\/details>\n<details>\n<summary>What is a blunt microcannula?<\/summary>\n<p>A blunt microcannula is a fine filler cannula with a rounded, closed tip and a side opening set back from it, passed through a needle puncture and threaded along one plane. The facial techniques cited here use sizes from 18G to 27G in lengths of 30 to 70 mm. Gauge decides its force advantage: in Ugradar&#8217;s test, 18G and 22G microcannulas never entered the facial artery, and finer ones went in with a low amount of force.<\/p>\n<\/details>\n<details>\n<summary>Which facial areas take a filler cannula, and which take a needle?<\/summary>\n<p>The cannula takes the long tracks through fat and between fasciae: the temple between the temporal fasciae, the tear trough deep to the orbicularis, the deep cheek fat, the perialar space, the nasolabial fold, the nasal dorsum, the marionette lines, the jawline and the subcutaneous chin. The needle takes bone-level depots and short, exact deposits: the deep temple on bone, the zygomaticomalar junction, the deep pyriform space, the nasal radix and tip, and the chin points on bone. Signorini&#8217;s 2016 panel preferred blunt cannulas in the glabella, alar base, nose and temple, and Goodman&#8217;s 2020 consensus rated them safer in the brow and the lateral and anterior cheek. The area table gives the entry, plane and gauge for each.<\/p>\n<\/details>\n<details>\n<summary>Can you see a filler cannula on ultrasound?<\/summary>\n<p>Yes. On a high-frequency linear probe held along the shaft, a cannula shows as a bright straight line with the tip at its leading end and stacked reverberation echoes beneath it; with the probe turned across it, the shaft becomes a bright dot. Fresh HA spreads as a dark pool around the tip. The image fades as the entry steepens, by 0.18 on the log-odds scale per degree across 1,500 cadaver clips (Dinges 2023), and the published face frames read the tip at 18, 20 and 24 MHz. On Suresult probes, Needle Enhance and the in-plane and out-of-plane guides keep the shaft and its path on screen.<\/p>\n<\/details>\n<details>\n<summary>Should you scan before a filler cannula pass, or while injecting?<\/summary>\n<p>Scan before every pass, and during it in the areas the consensus names. Teixeira&#8217;s map-first technique took 1 to 3 minutes per session in 503 patients and steered the cannula&#8217;s plane away from the mapped artery, against 5 to 20 minutes for real-time guidance. The 2025 Delphi panel makes the map before injecting mandatory for the forehead, glabella, temple, nose and pyriform fossa, and recommends guiding the injection itself there and in the pre-auricular region, mandible, chin, zygomatic arch and lower eyelid. Rocha&#8217;s three-step method adds a rescan of perfusion after the filling.<\/p>\n<\/details>\n<details>\n<summary>How do you run an ultrasound-guided filler cannula pass in the tear trough?<\/summary>\n<p>Map the vessels along the rim first: the angular vein runs inside the orbicularis 3.8 to 4.6 mm above the orbital rim (Calomeni 2022), so a cannula deep to the muscle passes beneath it. Bernardini&#8217;s 2025 technique set the display depth to 1.5 cm at 20 to 23 MHz, entered laterally with a 25G 50 mm cannula and placed product deep to the orbicularis oculi and below the tear trough ligament in 6 to 8 passes of 0.02 to 0.04 mL, 0.26 mL per side on average, across 246 sides. On a Suresult probe, the L24Pro&#8217;s 15 mm preset at 24 MHz frames that plane, as does the L20Pro&#8217;s 20 mm preset at 20 MHz.<\/p>\n<\/details>\n<details>\n<summary>What MHz probe shows a filler cannula and the facial arteries?<\/summary>\n<p>At least 15 MHz, the floor set by the 2025 Delphi panel and the WFUMB 2025 position paper, and 18 to 24 MHz on shallow tracks, where the published cannula-tip frames were read. At 20 MHz the image reaches about 10 mm, which holds the supratrochlear and supraorbital arteries at 3.34 and 3.54 mm and the frontal branch of the superficial temporal artery at 2.7 mm, while the bone plane under the cheek calls for a deeper preset. The Suresult L20Pro covers both at 16\/20 MHz on 10 to 40 mm presets, the L24Pro adds 24 MHz on 10 to 25 mm, and the <a href=\"\/high-frequency-ultrasound-machine\/\">high-frequency ultrasound guide<\/a> sets 20 against 24 MHz.<\/p>\n<\/details>\n<details>\n<summary>What is the best handheld ultrasound for filler cannula work?<\/summary>\n<p>The Suresult L20Pro, at 89.3\/100 under the protocol declared October 29, 2026, ahead of the Clarius L20 HD3 (69.8), the GE Vscan Air SL (48.3), the Butterfly iQ3 (47.6) and the Philips Lumify L12-4 (41.4). Needle Enhance and in-plane and out-of-plane guides come in its price, along with 16\/20 MHz on 10 to 40 mm presets, Color, Power and PW Doppler and 3 months of FaceAtlas AI, for a five-year total of {{SRX_TOTAL:P31250+S36383}} with the lifetime license, on sale until 11:59 PM PT, December 31, 2026. The Clarius L20 HD3 places second, with a live vessel-depth readout and Needle Enhance in its Essentials membership.<\/p>\n<\/details>\n<details>\n<summary>How do you use a filler cannula, step by step?<\/summary>\n<p>Map the track in B-mode and Color Doppler and mark each artery it crosses; choose the plane against the map; open the entry with a needle that matches the cannula or runs up to two sizes larger; advance in-plane with the whole shaft and tip on screen; deposit on withdrawal in aliquots under 0.1 mL; turn the probe across the shaft near a vessel to confirm the tip sits outside it; then rescan the deposit and the flow and save the loop. The eight steps, each with its source, are in the step-by-step section above.<\/p>\n<\/details>\n<details>\n<summary>Do you need a sterile probe for a filler cannula pass?<\/summary>\n<p>Yes, for scanning during the pass: guided injection runs with sterile coupling between probe and skin, set out in the <a href=\"\/ultrasound-guided-filler-injections\/#sterile-coupling\">sterile coupling section of the guided filler injections guide<\/a>, while the map before the entry runs on gel over intact skin. For the pass itself, Suresult&#8217;s <a href=\"\/shop\/accessories\/aesthetic-ultrasound-gel-pads\/\">aesthetic ultrasound gel pads<\/a> are sterile \u00d835 \u00d7 4 mm hydrogel discs: the probe rests on the pad and the needle goes straight through it, at {{SRX_PRICE:36977}} for 50.<\/p>\n<\/details>\n<\/div>\n<\/section>\n<section id=\"related\">\n<h2>Related guides<\/h2>\n<ul class=\"sr-can-related\">\n<li><a href=\"\/vascular-occlusion-filler\/\">Vascular occlusion after filler: the signs and the Doppler map<\/a><\/li>\n<li><a href=\"\/ultrasound-guided-filler-injections\/\">Ultrasound-guided filler injections: the full workflow<\/a><\/li>\n<li><a href=\"\/ultrasound-guided-filler-dissolving\/\">Filler dissolving under ultrasound guidance<\/a><\/li>\n<li><a href=\"\/lip-filler-technique-ultrasound\/\">Lip filler technique with ultrasound<\/a><\/li>\n<li><a href=\"\/best-aesthetic-ultrasound-machines-for-facial-fillers\/\">The best aesthetic ultrasound machines for facial fillers<\/a><\/li>\n<li><a href=\"\/aesthetic-ultrasound-cost\/\">What aesthetic ultrasound costs: probe, software and the five-year total<\/a><\/li>\n<li><a href=\"\/l20-vs-l24-aesthetic-ultrasound\/\">L14, L20 or L24 for aesthetic work<\/a><\/li>\n<li><a href=\"\/high-frequency-ultrasound-machine\/\">High-frequency ultrasound: 15, 20 or <span class=\"sr-nw\">24 MHz<\/span> for the face<\/a><\/li>\n<li><a href=\"\/best-portable-doppler-ultrasound\/\">Portable Doppler ultrasound handhelds, ranked<\/a><\/li>\n<li><a href=\"\/best-ultrasound-for-nerve-blocks\/#needle-visibility\">Needle visibility tools on handheld ultrasound<\/a><\/li>\n<li><a href=\"\/specialty\/handheld-ultrasound-for-aesthetics\/\">Suresult handhelds for aesthetic practice<\/a><\/li>\n<\/ul>\n<\/section>\n<section id=\"sources\">\n<h2>Sources<\/h2>\n<ol class=\"sr-sources\">\n<li id=\"source-1\"><a href=\"https:\/\/doi.org\/10.1001\/jamadermatol.2020.5102\" target=\"_blank\" rel=\"noopener noreferrer nofollow\">Alam M, Kakar R, Dover JS, et al.

\"Question\", \"name\": \"Is a filler cannula safer than a needle?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"At 22G and 25G, yes on the bench: a 22G cannula needed 1.50 N to enter a facial or superficial temporal artery against 1.08 N for a 22G needle, and 1.04 N against 0.69 N at 25G, while at 27G the two showed no significant difference, 0.78 vs 0.70 N (Pavicic 2019). Across 370 US dermatologists surveyed by Alam in 2021, cannula use carried 77.1% lower adjusted odds of vascular occlusion. The consensus papers set the line at 25G or larger, and a scan of the track shows where the artery runs before the entry; the signs and first steps after an occlusion are in the vascular occlusion guide.\"}}, {\"@type\": \"Question\", \"name\": \"Can a filler cannula enter an artery?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes, and the finer the cannula, the easier it goes in. In Ugradar's 2019 study of 20 hemifaces, 18G and 22G microcannulas never entered the facial artery, while 23G, 25G and 27G cannulas did, at less force the finer they were. Siperstein's 2023 bench test of three brands at 22 to 30G found every cannula needed more force than the matching needle, with arterial entry taking numerous attempts, and Tansatit's 2017 dissections showed a 25G cannula perforating the frontal branch of the superficial temporal artery in specific situations, when it met the vessel at a right angle. A fibrous septum and an artery wall feel the same at the cannula tip, so the scan, not the hand, shows where the artery runs.\"}}, {\"@type\": \"Question\", \"name\": \"Which facial areas carry the most filler risk, and where is a filler cannula preferred?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The glabella, alar base, nose and temple: Signorini's 2016 global panel names them as areas associated with higher risks of vascular complications and prefers blunt cannulas there. The 2025 Delphi panel lists the forehead, glabella, temple, nose and pyriform fossa as the areas where a vessel map before filler is mandatory, and the area table above gives the entry, plane and gauge for each.\"}}, {\"@type\": \"Question\", \"name\": \"What gauge filler cannula should you use?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"25G or larger for most of the face. The upper-face and midface best-practice papers recommend blunt cannulas of 25G or larger for the forehead, glabella, temple and tear trough (Sigrist 2024; Vasconcelos-Berg 2024); Goodman's 2020 consensus puts cannulas finer than 25G closer to needles in how they pierce vessels; and a 27G cannula enters an artery with about the force of a 27G needle (Pavicic 2019). Hong's 2024 review uses 21\u201323G for deep work near muscle and 25\u201327G for superficial planes.

In Jones's 2021 randomized split-face cheek trial of 60 subjects, pain scored 2.3 on the cannula side against 3.1 on the needle side, and bruising on that side alone ran 8.3% against 20.0%. Goodman's 2020 consensus rates cannulas safer in the lateral and anterior cheek.

Filler needles in the cited protocols run about 13 mm, while cannulas run 30 to 70 mm, so one entry reaches a whole track.

The facial techniques cited here use sizes from 18G to 27G in lengths of 30 to 70 mm. Gauge decides its force advantage: in Ugradar's test, 18G and 22G microcannulas never entered the facial artery, and finer ones went in with a low amount of force.\"}}, {\"@type\": \"Question\", \"name\": \"Which facial areas take a filler cannula, and which take a needle?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The cannula takes the long tracks through fat and between fasciae: the temple between the temporal fasciae, the tear trough deep to the orbicularis, the deep cheek fat, the perialar space, the nasolabial fold, the nasal dorsum, the marionette lines, the jawline and the subcutaneous chin. The needle takes bone-level depots and short, exact deposits: the deep temple on bone, the zygomaticomalar junction, the deep pyriform space, the nasal radix and tip, and the chin points on bone. Signorini's 2016 panel preferred blunt cannulas in the glabella, alar base, nose and temple, and Goodman's 2020 consensus rated them safer in the brow and the lateral and anterior cheek.

On a high-frequency linear probe held along the shaft, a cannula shows as a bright straight line with the tip at its leading end and stacked reverberation echoes beneath it; with the probe turned across it, the shaft becomes a bright dot. Fresh HA spreads as a dark pool around the tip. The image fades as the entry steepens, by 0.18 on the log-odds scale per degree across 1,500 cadaver clips (Dinges 2023), and the published face frames read the tip at 18, 20 and 24 MHz. On Suresult probes, Needle Enhance and the in-plane and out-of-plane guides keep the shaft and its path on screen.\"}}, {\"@type\": \"Question\", \"name\": \"Should you scan before a filler cannula pass, or while injecting?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Scan before every pass, and during it in the areas the consensus names. Teixeira's map-first technique took 1 to 3 minutes per session in 503 patients and steered the cannula's plane away from the mapped artery, against 5 to 20 minutes for real-time guidance. The 2025 Delphi panel makes the map before injecting mandatory for the forehead, glabella, temple, nose and pyriform fossa, and recommends guiding the injection itself there and in the pre-auricular region, mandible, chin, zygomatic arch and lower eyelid. Rocha's three-step method adds a rescan of perfusion after the filling.\"}}, {\"@type\": \"Question\", \"name\": \"How do you run an ultrasound-guided filler cannula pass in the tear trough?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Map the vessels along the rim first: the angular vein runs inside the orbicularis 3.8 to 4.6 mm above the orbital rim (Calomeni 2022), so a cannula deep to the muscle passes beneath it. Bernardini's 2025 technique set the display depth to 1.5 cm at 20 to 23 MHz, entered laterally with a 25G 50 mm cannula and placed product deep to the orbicularis oculi and below the tear trough ligament in 6 to 8 passes of 0.02 to 0.04 mL, 0.26 mL per side on average, across 246 sides. On a Suresult probe, the L24Pro's 15 mm preset at 24 MHz frames that plane, as does the L20Pro's 20 mm preset at 20 MHz.\"}}, {\"@type\": \"Question\", \"name\": \"What MHz probe shows a filler cannula and the facial arteries?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"At least 15 MHz, the floor set by the 2025 Delphi panel and the WFUMB 2025 position paper, and 18 to 24 MHz on shallow tracks, where the published cannula-tip frames were read. At 20 MHz the image reaches about 10 mm, which holds the supratrochlear and supraorbital arteries at 3.34 and 3.54 mm and the frontal branch of the superficial temporal artery at 2.7 mm, while the bone plane under the cheek calls for a deeper preset. The Suresult L20Pro covers both at 16\/20 MHz on 10 to 40 mm presets, the L24Pro adds 24 MHz on 10 to 25 mm, and the high-frequency ultrasound guide sets 20 against 24 MHz.\"}}, {\"@type\": \"Question\", \"name\": \"What is the best handheld ultrasound for filler cannula work?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The Suresult L20Pro, at 89.3\/100 under the protocol declared October 29, 2026, ahead of the Clarius L20 HD3 (69.8), the GE Vscan Air SL (48.3), the Butterfly iQ3 (47.6) and the Philips Lumify L12-4 (41.4).
