A blunt filler cannula and a sharp needle reach the same planes by different routes, and the handheld I pick to watch both tips under the skin is the Suresult L20Pro at $3,720: 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’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’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.
Reikwijdte van de beoordeling: I am an independent device reviewer with deep ultrasound knowledge, and for this ranking I rated needle and cannula tracking tools, top linear frequency, image depth, Doppler modes, filler and vessel software, records and five-year cost for the Suresult L20Pro, L24Pro, L14Pro, L20, L24 and L14, the GE Vscan Air SL, the Clarius L20 HD3 and its L15 HD3 sibling, the Butterfly iQ3 and the Philips Lumify L12-4, measured against the published force, placement and tip-visibility studies on filler cannulas and needles, reading the Suresult product pages on October 30, 2026 and the rival stores, manuals and PubMed records on October 29 and 30, 2026.
Quick answer: filler cannula or needle, and which handheld shows the tip?
Use a blunt filler cannula of 25G or wider to lay volume along long tracks through fat and between fasciae, in the cheek, temple, tear trough, jawline and across the forehead, and a needle for small, exact depots on bone, at the chin point and in shallow dermal work. At 22G and 25G a cannula needs more force than a needle of the same gauge to enter an artery, and the gap closes at 27G (Pavicic 2019); to keep occlusion risk down, the best-practice papers for the upper face and midface set 25G as the narrowest cannula (Sigrist 2024; Vasconcelos-Berg 2024). Cannula injections carried 77.1% lower adjusted odds of vascular occlusion in Alam’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.
The Suresult L20Pro ($3,720) is the handheld I rank first for filler cannula and needle work, at 89.3/100. 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 $4,719.
The Clarius L20 HD3 is second at 69.8, an 8–20 MHz linear to 4 cm whose Needle Enhance, PW Doppler and Vessel Depth AI come with the Clarius Essentials membership.
Five handhelds compared for filler cannula and needle guidance
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.

Is a filler cannula safer than a needle?
At 22G and 25G, yes: a blunt tip needs more force to enter an artery than a sharp one, and the margin shrinks as the cannula narrows. Pavicic’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’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’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 vascular occlusion guide.
| Gauge | Needle | Cannula | Onderzoek |
|---|---|---|---|
| 22G | 1.08 ± 0.25 N | 1.50 ± 0.31 N | Pavicic 2019, 294 penetrations of facial and superficial temporal arteries |
| 25G | 0.69 ± 0.24 N | 1.04 ± 0.36 N | Pavicic 2019 |
| 27G | 0.70 ± 0.29 N | 0.78 ± 0.35 N, no significant difference (p = 0.558) | Pavicic 2019 |
| 22 to 30G, three cannula brands | Less force at every gauge | More force at every gauge; arterial entry took numerous attempts | Siperstein 2023 |
The hand cannot tell an artery from tissue at the tip. In Tansatit’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’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 0.72–0.81, 0.43–0.54 and 0.23–0.32 kg, less force the finer the cannula. Siperstein ties the outcome to each cannula’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).

| Bhojani-Lynch 2025 | 25G preferred; 27G not recommended, for the false sense of security it gives | Expert overview, infraorbital hollows |
| Pavicic 2019 | A 27G cannula is no safer than a 27G needle | 294 arterial penetrations |
| Hong 2024 | 21–23G for deep work near muscle, 25–27G for superficial planes; some facial vessels are wide enough to admit a 23G cannula | Review of vascular complications |
| Bae 2024 | Most frontal-branch segments of the superficial temporal artery measure below 1 mm inside, against 1.27 mm across an 18G cannula | Temple vessel measurements |
| Ugradar 2019 | Microcannulas finer than 22G entered the facial artery with a low amount of force | 20 hemifaces |
The consensus papers favor the cannula region by region. Signorini’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’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’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’s 2026 review of the temple, nose, lips and jawline weighs the cannula’s lower occlusion risk against the needle’s value for precise placement; and Lee’s 2026 review matches the device to the region, the indication and the operator’s skill, with ultrasound to confirm the plane. In Nikolis’s 2024 Safety Task Force of 16 experts from nine countries, 93% used cannulas for some injections and 43% used ultrasound.
Filler cannula vs needle in trials: bruising, pain and placement
Head-to-head trials favor the cannula on bruising and pain in most areas, and the infraorbital hollow is where the results split. In split-face nasolabial fold trials, the cannula side bruised less, 20.0% against 54.0% in Beer 2023, with less pain, edema, redness and hematoma in Hexsel 2012, and in Jones’s 2021 cheek trial pain scored 2.3 with the cannula against 3.1 with the needle. Under the eyes, Biesman’s 2024 trial logged more treatment-related events on the cannula arm, 20.9% against 4.9%, while Fabi’s 2021 trial counted more responders with a 27G cannula than with a 32G needle, 92.9% against 71.1%.
| Onderzoek | Area, design and size | With a needle | With a cannula |
|---|---|---|---|
| Hexsel 2012 | Nasolabial folds; double-blind split-face trial; 25 patients | More pain, edema, redness and hematoma | Less of each (p = .03, < .001, .01 and < .001) |
| Beer 2023 | Nasolabial folds; split-face trial; 50 patients; 27G ½” needle against 25G 2″ cannula | Bruising on 27 of 50 sides (54.0%) | Bruising on 10 of 50 sides (20.0%), p = 0.0004 |

| Spada 2023 | Tear troughs; split face; 10 adults; 31G needle against 25G cannula, scanned at 14 MHz | Tighter, more uniform deposit | Slightly less bruising; product more superficial |
Cadaver placement studies add the precision side. In ten foreheads imaged by fluoroscopy, CT and MRI, needle product changed plane in 60% of injections and cannula product in none (P = 0.003); the cannula spread 25.6 mm across against 13.5 mm for the needle and showed more backflow along its track, 90.2% against 33.3% (Pavicic 2017). On the forehead bone, Faria’s 2025 specimens received a 22G 50 mm cannula and a 27G 13 mm needle held at 45° bevel down, and both put the filler on the periosteum in every case, while the same needle at 90° spread it across several layers; in Pavicic’s 126 needle injections across the forehead, scalp, zygomatic arch and mandibular angle of seven donors, a 90° angle raised the odds of superficial spread tenfold against 10° bevel down (OR 10.0). Bone contact holds the tip for the cannula more than for the needle: in van Loghem’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. Surek’s 2016 study of the deep pyriform space, where the angular artery runs in the roof, describes on-bone injection there as free of vascular concern.
Filler cannula or needle by facial area: gauge, entry and plane
Area by area, the published techniques give the cannula the long tracks through fat and between fasciae and keep the needle for bone-level depots and short, exact deposits. The 2025 Delphi consensus sets which areas to map before the injection and where to guide the injection itself; the table under it gives the entry, plane, tool and gauge each area’s sources describe, with the vessel depths the probe has to reach on that track.
| Recommendation | Facial areas |
|---|---|
| Map before injecting: mandatory | Forehead, glabella, temple, nose and pyriform fossa |
| Map before injecting: recommended | Lips, lower eyelids, zygomatic arch, chin and pre-auricular region |
| Guide the filler injection with ultrasound: recommended | Forehead, glabella, temple, pre-auricular region, mandible, chin, nose, zygomatic arch, lower eyelid and pyriform fossa |

The nose splits the sources by layer. Lee’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’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’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.
What ultrasound shows at the filler cannula or needle tip
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 1–2 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).
| Factor | What the screen shows | Numbers | Bron |

On the Suresult L20Pro, L24Pro and L14Pro, Needle Enhance highlights the needle in the image, and the in-plane and out-of-plane puncture guides, with grid overlay and flip, give real-time direction while the shaft is held in the scan plane; the L20 and L24 carry the same set, and the L14 the guides alone. Read at 24 MHz and 20 mm on a Suresult L24, the same 18/24 MHz band as the L24Pro, the two clips below show what the screen gives: a needle shaft held in-plane as one bright line from the entry to the tip, and a needle line entering a bolus of hyaluronic acid that spreads as a dark, anechoic pool around the tip.
A gel pad keeps the coupling steady through an in-plane pass. The Suresult aesthetic ultrasound gel pads are sterile Ø35 × 4 mm hydrogel discs: the probe sits on the pad, not on the skin, a needle goes straight through the hydrogel, and the second hand stays free to stretch the skin or inject. Centered under the 25 mm footprint, a pad leaves about 5 mm spare at each end of the probe for an in-plane entry, and the 4 mm stand-off takes 4 mm of the display depth, so the L20Pro’s 40 mm preset still shows about 36 mm of tissue. A pack of 50 costs $140, and the sterile setup for scanning during the pass is in the sterile coupling section of the guided filler injections guide.
Where the filler lands: ultrasound-checked cannula and needle passes
Scanned after the pass, cannula product stays in the plane it was aimed at in most published series: a 22G cannula put filler in the intended deep midfacial compartment in all 188 midfaces of 94 volunteers (Schelke 2023, 188 midfaces), a 25G cannula placed it deep to the orbicularis oculi in all 246 tear troughs (Bernardini 2025), and across 100 injections the plane held in about 90% at day 0, 14 and 30 (Calomeni 2023). Where the two tools went head to head, the plane decided more than the instrument: across 440 guided areas, angle, cannula or needle and gauge left the spread of HA unchanged, and product stayed superficial or deep to the SMAS where it was placed (Schelke 2026).
| Onderzoek | Area and size | Tool and imaging | Where the filler went |
|---|---|---|---|
| Schelke 2023, 188 midfaces | Midface deep fat; 94 volunteers | 22G cannula, ultrasound-assisted | The intended deep compartment in 100%, with no adverse events |
| Bernardini 2025 | Tear troughs; 246 sides in 123 patients | 25G 50 mm cannula from a lateral entry; 20–23 MHz | Deep to the orbicularis oculi and below the tear trough ligament on every side, 0.26 mL per side on average |
| Calomeni 2023 | Several facial areas; 100 injections in 8 patients | Cannula, with real-time ultrasound to day 30 | The plane held in about 90% at day 0, 14 and 30; deposit area 22.51, 15.97 and 12.9 mm² |
| Faria 2025 | Forehead; 4 specimens, 5 injectors | 22G 50 mm cannula; 27G 13 mm needle at 45° and at 90° | On the periosteum in every cannula pass and every 45° needle pass; spread across layers at 90° |
| Bravo 2021 | Zygoma, chin and temple; 1 patient, split face | 22G 5 cm cannula against a 27G needle; 8–18 MHz lineair | On bone with both tools at the zygoma and chin; above bone with the cannula in the temple |
| Ahn 2024 | Forehead and temple; 3 cadaver hemifaces and 2 volunteers | 18G or 21G cannula from a single entry; 18 MHz | Supraperiosteal in the forehead and on the deep temporal fascia in the temple, on target in all |
| Surek 2021 | Temple; 20 cadaver hemifaces | Ultrasound-guided injection into the intermediate temporal fat pad | On target in 18 of 20 (90%); the temporalis in 2 of 20 |
| Schelke 2026 | Face; 440 areas in 107 women | 27G needle and 25G cannula; 18 or 20 MHz | Spread held to its plane, superficial or deep to the SMAS; angle, tool and gauge left the flow unchanged |
Five details decide whether a cannula reaches the plane it is aimed at. 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.
How to run a guided filler cannula pass, step by step
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’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’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 workflows section of the ultrasound-guided filler injections guide; the steps below apply it to a cannula.
- Map the track. 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.
- Choose the plane against the map. 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.
- Open the entry. 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).
- Advance in-plane. 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. A 25 mm field shows the leading half of a 50 mm cannula, so slide the probe along the track as the tip advances.
The nasolabial fold scanned while injecting: the probe held in-plane along the cannula, and on color Doppler at 18 MHz the cannula in the subcutaneous fat with its tip (*) outside the vessels and the facial artery just deep to it. Figure 10 from Vasconcelos-Berg R, Desyatnikova S, Bonavia P, et al. Diagnostics (Basel) 2024;14(22):2544. doi:10.3390/diagnostics14222544. CC BY 4.0. - Deposit in small retrograde aliquots. Inject on withdrawal in aliquots under 0.1 mL (Goodman 2020); in the temple, Ko’s 2026 study pairs a low-resistance track opened by hydrodissection with low-pressure, retrograde micro-aliquots.
- Bring back a lost tip. If the tip leaves the screen, slide or rotate the probe in small moves until the shaft shows again; where the plane itself is hard to see, as between the temporal fasciae, a small test aliquot confirms it as a dark pool between two bright fascial lines (Desyatnikova 2022).
The temple on color Doppler at 20 MHz: the cannula tip (*) in the interfascial plane between the superficial temporal fascia and the superficial layer of the deep temporal fascia. Figure 3 from Sigrist R, Desyatnikova S, Chammas MC, et al. Diagnostics (Basel) 2024;14(16):1718. doi:10.3390/diagnostics14161718. CC BY 4.0. - Check out-of-plane near a vessel. Turn the probe 90° where the track nears a mapped vessel: the shaft becomes a dot, and the scan confirms the tip sits outside the lumen, with 1–2 mm between cannula and vessel before injecting (Sigrist 2024). Aspiration pulls the tip 1.1–5.3 mm back and injection pushes it 0.6–4.1 mm forward (Lin 2022), so the check follows the tip after each change of pressure.
- Rescan and save. After the last pass, image the deposit in B-mode, confirm flow on the mapped vessels in Color Doppler, and save the loop to the client’s record, the final step of Rocha’s method (Rocha 2022).
Doppler settings for the vessels on a cannula track
The arteries a cannula track crosses run slowly and close to the surface: the supratrochlear, supraorbital and angular arteries measure 0.6 to 1.0 mm inside, with peak systolic velocities of 9.2 to 24.9 cm/s (Shen 2023, 74 hemifaces). A velocity scale near 3 cm/s, with PRF and wall filter brought down to suit it, fills those vessels with color (Sigrist 2026); scan across each vessel, steer the color box along it (Sigrist 2024), and keep plenty of gel under a light hand.
| Setting | Starting point | Bron | On the Suresult app |
|---|---|---|---|
| Velocity scale | Over ons 3 cm/s, so slow facial flow fills the color box | Sigrist 2026 | Set through PRF on the color screen |
| PRF and wall filter | Brought down with the scale, since a high wall filter removes slow flow | Sigrist 2026 | PRF and WF controls; the frame below reads PRF 1.0 K and WF 3 |
| Color box | Steered along the vessel, with the probe across it | Sigrist 2024 | Steer control; 12° on the frame below |
| Koppeling | Abundant gel and minimal pressure, so shallow vessels stay open | Sigrist 2026 | The Ø35 × 4 mm gel pad carries the probe on hydrogel |
| Modi | Color to map, Power for the slowest flow, PW to confirm an arterial waveform | Delphi 2025; WFUMB 2025 | Color, Power and PW Doppler on every L-series probe |
| Frequentie | 15 MHz or more, and 18 to 24 MHz on shallow tracks | Delphi 2025; WFUMB 2025; Sigrist 2024 | 20 MHz on the L20Pro, 24 MHz on the L24Pro |
| Registratie | Stills and a loop of the map before the entry | Delphi 2025 | Cine to 1.000 frames; DICOM export |
Power Doppler picks up slower flow than color (WFUMB 2025), PW Doppler tells an artery from a vein by its waveform, and probe compression separates the two as well (Lee 2023). The full Doppler setup for guided filler, mode by mode, is in the Doppler setup section of the guided filler injections guide. On the Pro probes, a track setting saves as one of 3 customizable user sets.
The rescan after the last cannula pass
After the last pass, rescan the whole track. 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’s 100 injections. Color Doppler then confirms flow on every vessel mapped before the entry, the last step of Rocha’s method. Saved with the map, the loop becomes the baseline for the next visit, and FaceAtlas AI keeps it in the client’s file for a one-click comparison; old product found at a later visit is read in the filler identification section of the dissolving guide.
What frequency shows a filler cannula and the vessels around it
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; the bone plane under the cheek calls for the deeper presets.
| Area and plane | Depth to reach | Frequency in the studies | Suresult setting that frames it |
|---|---|---|---|
| Forehead and glabella, supraperiosteal | Supratrochlear and supraorbital arteries 3.34 and 3.54 mm from the skin | 18 and 20 MHz | L20Pro at 20 MHz on the 10 or 20 mm preset; L24Pro at 24 MHz on 10 or 15 mm |
| Temple, subdermal and interfascial | Frontal branch of the superficial temporal artery 2.7 mm from the skin | 14 to 24 MHz | L20Pro at 20 MHz on 10 or 20 mm; L24Pro at 24 MHz on 10 or 15 mm |
| Tear trough, deep to the orbicularis | Angular vein 3.8–4.6 mm above the orbital rim, on a 15 mm display depth | 20 to 23 MHz | L24Pro at 24 MHz on the 15 mm preset; L20Pro at 20 MHz on 20 mm |
| Deep pyriform space, on bone | Arteria angularis 3.6 mm from the skin, with bone 9.11 mm down | 20 MHz | L20Pro at 20 MHz on 20 mm |
| Cheek and zygoma, deep fat and supraperiosteal | The bone plane over the zygoma and maxilla, under the deep fat compartments | 18 MHz | L20Pro at 16 MHz on 30 or 40 mm |
| Nasolabiale plooi | Arteria facialis 7.95 mm deep at the cheilion and 8.04 mm at the ala, pooled | 18 MHz | L20Pro at 20 MHz on 20 mm |
| Nose, on bone and cartilage | Subcutis 2.02 mm thick at the rhinion and 5.21 mm at the sellion | 18 to 20 MHz | L24Pro at 24 MHz on 10 mm; L20Pro at 20 MHz on 10 mm |
| Jawline and prejowl, subcutaneous | Arteria facialis 6.27 mm deep at the mandibular border, pooled | 18 MHz; 11 MHz in a 10-patient series | L20Pro at 20 MHz on 20 mm |
On a Suresult probe the cannula areas split by band. The L20Pro covers the whole list at 16/20 MHz: 20 MHz on the 10 and 20 mm presets for the forehead, temple, nose, fold and jawline tracks, and 16 MHz on the 30 and 40 mm presets for the bone plane under the cheek. The L24Pro adds 24 MHz on 10 to 25 mm presets for the tear trough and the temple subdermis, and the L14Pro at 10/14 MHz reaches 80 mm for body work beside the face. The frequency window by depth en de L14, L20 and L24 chooser for aesthetics set the bands side by side.

Hoe ik de scores bepaalde
I scored each maker’s card out of 100 on seven weighted criteria, declared on October 29, 2026, before a single rival was scored: tip visibility 20, superficial detail 20, depth reach 10, Doppler 20, filler software 10, records 5 and five-year cost 15. 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.
- 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.
- Superficial detail (20): the top linear frequency, scored 20 × (MHz − 10) ÷ 14 and held between 0 and 20: 20 at 24 MHz, 14.29 at 20 MHz and 2.86 at 12 MHz.
- Depth reach (10): 10 × (maximum image depth in mm − 20) ÷ 20, held between 0 and 10, so 40 mm or more scores the full 10 and 25 mm scores 2.5.
- 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.
- 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 3 maanden of FaceAtlas AI on the Pro probes count as included, and so does a rival tool sold with no tier named.
- Records (5): 2 for 60 seconds 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.
- Five-year cost (15): 15 × the lowest five-year total among the scored models ÷ this model’s total. Suresult totals add the FaceAtlas AI lifetime license to the price listed on October 30, 2026; Clarius totals add Essentials bought once, Butterfly totals five years of Advanced, and the Philips total is the PartsSource price. The Suresult L14 with the lifetime license, at $3,138, is the reference.

Family members sit inside their maker’s card: Suresult L24Pro 86.6, L20 86.1, L24 83.1, L14Pro 81.3 and L14 70.7; Clarius L15 HD3 62.6. 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.
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. The Philips Lumify L12-4 stays fifth in each of them. Every rival figure was read from the maker’s US pages or the PartsSource listing on October 29 and 30, 2026, and every Suresult figure from its product pages.
Filler cannula and needle questions
Is a filler cannula safer than a needle?
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.
Can a filler cannula enter an artery?
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.
Which facial areas carry the most filler risk, and where is a filler cannula preferred?
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.
What gauge filler cannula should you use?
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 21–23G for deep work near muscle and 25–27G 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.
What needle size opens the entry for a filler cannula?
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’s 2023 series punctured the skin with a 25G needle at 45°.
Which filler cannula size suits the cheeks?
A 22G or 25G cannula into the deep cheek fat. Schelke’s 2023 ultrasound-assisted series placed product with a 22G cannula in the intended deep midface compartment in all 188 midfaces; Galadari’s 2022 technique takes a 25G 38 mm cannula through a 23G introducer opened to bone at 90°; and Jones’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’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.
Which filler cannula suits the tear trough?
A 25G cannula about 50 mm long, from a lateral entry. Bernardini’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’s 2025 overview prefers 25G and advises against 27G for the false sense of security it gives; and Wilde’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.
Is a filler cannula better for cheek filler?
For bruising and pain, the trial data favor it. 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. 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.
Does a filler cannula hurt less than a needle?
In the folds and cheeks, yes: the cannula side hurt less in Hexsel’s 2012 split-face nasolabial fold trial of 25 participants (P = 0.03), pain scored 2.3 against 3.1 in Jones’s 2021 split-face cheek trial of 60 subjects, and Fulton’s 95 patients scored their pain at 3 with a cannula against 6 with a needle, with the same aesthetic improvement.
What is the difference between a filler cannula and a needle?
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’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.
What is a blunt microcannula?
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’s test, 18G and 22G microcannulas never entered the facial artery, and finer ones went in with a low amount of force.
Which facial areas take a filler cannula, and which take a needle?
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. The area table gives the entry, plane and gauge for each.
Can you see a filler cannula on ultrasound?
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.
Should you scan before a filler cannula pass, or while injecting?
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.
How do you run an ultrasound-guided filler cannula pass in the tear trough?
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.
What MHz probe shows a filler cannula and the facial arteries?
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.
What is the best handheld ultrasound for filler cannula work?
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 $4,719 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.
How do you use a filler cannula, step by step?
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.
Do you need a sterile probe for a filler cannula pass?
Yes, for scanning during the pass: guided injection runs with sterile coupling between probe and skin, set out in the sterile coupling section of the guided filler injections guide, while the map before the entry runs on gel over intact skin. For the pass itself, Suresult’s aesthetic ultrasound gel pads are sterile Ø35 × 4 mm hydrogel discs: the probe rests on the pad and the needle goes straight through it, at $140 for 50.

Choose the probe around your cannula list
For every cannula area on one probe, from the temple branch at 2.7 mm to the bone plane under the cheek, I recommend the L20Pro at $3,720. For the tear trough and the temple subdermis at 24 MHz, I choose the L24Pro at $4,185. Practices that image the body as well take the L14Pro at $3,441, whose presets reach 80 mm. Orders ship within 24 hours; each Pro arrives with a 30-day worry-free trial and a 2-year warranty that extends to 3 or 5 years; and the checkout price already includes customs and duties: No Hidden Fees.
