Background
Multiple penetration depths of high-intensity focused ultrasound (HIFU) treatment for facial rejuvenation have not been quantified.
Methods
We enrolled 12 participants (n=24) to undergo one session of HIFU rejuvenation between January 1, 2019, and January 10, 2020. We used a 2-, 4.5-, and 6-mm focal depth transducer on the upper and middle face. We evaluated efficacy on days 60 and 90 by using our specific assessment system.
Results
The average eyebrow peak and pupil–eyebrow peak angles significantly increased by 2° (p < 0.0005) and decreased by 1° (p < 0.0001), respectively, at day 90. The shortened eyebrow–iris length indicated that the forehead tissues had lifted and moved medially to the central face. Supraorbital tissues were also vertically elevated, marked by the eyebrow–orbital (p = 0.0016) and vertical palpebral fissure lengths (p = 0.0052), which both exhibited a 0.8-cm elevation. For the midface, the increased canthus–oral–nasal angle (p = 0.5881) and decreased tragus–oral length (p = 0.5881) indicated that laxity had been corrected through lifted oral commissure, though the data were not statistically significant. No serious side effects were observed.
Conclusion
HIFU treatment with multiple depths quantitatively improved both upper-facial rejuvenation and midface rejuvenation after a single session.

“…15 Angular and linear measurements of various facial landmarks are assessed by Morpheus 3D ® before treatment and during subsequent follow-ups at 2, 4, 12, and 24 weeks posttreatment. The facial and cephalometric measurements are done as described by Tsai et al (2021), with focus on the angular measurements of eyebrow peak, eyebrow tail, pupil-eyebrow peak, and the linear measurements of eyebrow-orbital, orbital-eyelid, eyebrowiris, tragus-oral, and lower facial contouring lengths (Figure 1). 17…”

Background
The aging face is characterized by skin laxity and volume loss. Attenuation of facial retaining ligaments significantly contributes to skin sagginess and soft tissue volume loss.
Aims
We designed a prospective cohort study to quantitatively assess the efficacy of hyaluronic acid (HA) with adjunct poly‐L‐lactic acid (PLLA) injections in strengthening the retaining ligaments.
Patients/Methods
A total of 12 Asian women were treated with HA injections to the orbital, zygomatic, buccal‐maxillary, and mandibular retaining ligaments with adjunct supraperiosteal and subdermal PLLA injections to the temporal region, midface, and lower face. Cephalometric measurements were done before treatment and 2, 4, 12, and 24 weeks post‐procedurally.
Results
Eyebrow peak and tail angles increased 20.0° ± 3.8° to 21.0° ± 3.8° (p < 0.05) and −2.9° ± 4.2° to −1.3° ± 3.3° (p < 0.001) at week 12. Eyebrow‐to‐orbital‐rim distance increased 1.9 ± 2.0 mm to 3.9 ± 1.5 mm (p < 0.001) at week 12. Eyebrow‐to‐upper‐eyelid distance increased 11.6 ± 3.0 mm to 12.7 ± 3.2 mm (p < 0.001) at week 24. Eyebrow‐peak‐to‐lateral‐limbus distance decreased 6.1 ± 3.1 mm to 5.3 ± 2.4 mm (p < 0.05) at week 4. Tragus‐oral‐commissure length and lower‐facial‐contouring length decreased 281 ± 11 mm to 275 ± 10 mm (p < 0.01) and 297 ± 14 to 292 ± 11 mm (p < 0.05) at week 12, respectively.
Conclusion
Hyaluronic acid injection for strengthening of facial retaining ligaments with adjunct PLLA is viable, safe, and effective in facial rejuvenation as supported by quantitative data.
“…The four angles, consisting of one mobile point and two static points in each, are the eyebrow-peak, eyebrow-tail, pupil-eyebrow peak, and canthus-oral-nasal angles. 1 , 2 The deviation values postprocedure for each range from −10 to +10 degrees. Four linear lengths are used to describe the aging of periocular region: eyebrow–orbital, orbital–upper eyelid, vertical palpebral fissure, and eyebrow–iris lengths, which change rather subtly with the range from −3 mm to +3 mm.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
