Efficacy of Microfocused Ultrasound Treatment on Malar Mounds in Brazilian Patients: A Prospective Study at the Professor Rubem David Azulay Dermatology Institute

Abstract This study evaluates the efficacy and safety of the use of Micro focused Ultrasound on the Atria(R) LMG(R) platform as a treatment for Malar Mound. In addition, a specific protocol was developed to improve patients' aesthetic complaints. Introduction Malar Mound is the accumulation of edema, sagging or permanent fat in the prezygomatic region. Micro focused Ultrasound is a new and safe technology that, through heat, generates neocollagenesis, causing rejuvenation of the treated area. Objective To determine the level of effectiveness of using Micro focused and Macro focused Ultrasound on the ATRIA(R) LMG(R) platform in patients with Malar Mound. Methodology An experimental, prospective, single-center study was carried out at the Prof. Rubem Azulay Dermatology Institute between September 2024 and February 2025. The sample consisted of 13 people who underwent 5 sessions of Micro focused ultrasound every 2 weeks. High-frequency dermatological ultrasound was used to measure the soft tissues involved, and each patient completed questionnaires on satisfaction and adverse effects, as well as a photographic record before and after treatment. Results The result was a significant improvement in the Malar Mound in most of the patients. In the superficial musculoaponeurotic system of the medial and lateral malar region, on both the right and left sides, the results were statistically significant with a significance level of 5% (p<0.05). The satisfaction rate was acceptable, with 53.8% of the participants indicating that they were very satisfied. Only 3 patients reported edema, erythema or other side effects after the sessions. Conclusions Micro focused ultrasound proved to be effective and safe in the treatment of Malar Mound, with a high degree of patient satisfaction. A specific protocol was applied to treat the aesthetic complaint, the same one developed by the research participants. Side effects were mild and transient, reinforcing the viability of the non-surgical therapeutic alternative.
