Introduction
Since aesthetic medical treatments providing natural results are becoming increasingly popular, we developed an innovative hyaluronic acid infiltration technique for midface rejuvenation.
Methods
In this prospective study, only patients with a negative or neutral lower eyelid vector were included.
Treatment consisted in injecting three hyaluronic acid boluses at the cutaneous projections of the levator labii superioris, zygomatic major and minor muscles insertions. All patients were administered before treatment the FACE-Q questionnaire, whereas after treatment, they were administered the FACE-Q questionnaire and the Global Aesthetic Improvement Scale (GAIS). All treatments were documented with standardized photographs. A plastic surgeon from another Institution reviewed the photos and scored the treatments according to the GAIS scale.
Results
We included 567 patients (101 males and 466 females) who met the inclusion criteria. The mean age was 41 years, and mean follow-up time was four months. The FACE-Q scores after treatment were significantly higher (p < 0.001) in every domain investigated. The GAIS scores demonstrated significant improvement posttreatment in 89.8% of patients. An average of 1.5 ml of hyaluronic acid (VYC-20) was used for each zygomatic region. No major complications were reported; only 27 patients reported bruising, which resolved spontaneously. In all patients, there was an inversion of the lower eyelid vector, which had transitioned from neutral or negative to positive.
Conclusion
Lifting the insertions of three selected muscles with hyaluronic acid allows a midface upward repositioning. This technique provides a reproducible and safe approach for midface rejuvenation through tissue repositioning rather than augmenting facial volume.
