Use of Micro-focused Ultrasound for Skin Tightening of Mid and Lower Face.

Abstract

Background:The changes in the mid face and lower face are among the most prominent features of the aging process. Intense focused ultrasound, known as the Ulthera System (Ulthera Inc., Mesa, AZ, USA), was designed to correct this process. It employs micro-focused ultrasound to cause discrete focal heating of the dermis and stimulates neocollagenesis and elastin remodeling.Methods:This study enrolled 50 adult patients of Indian ethnicity who opted for correction of mid face and lower face sagging by Ulthera. The subjects were treated using Ulthera 3.0 mm probes which targets deep dermis and 4.5 mm, which targets the superficial muscular aponeurotic system. All patients were evaluated for allergic reactions and side effects like scarring and nerve/muscle dysfunction. Investigators Global Aesthetic Improvement Scales Scores and Patients Global Aesthetic Improvement Scales Scores were used for analysis at 30 days, 60 days, 3 months, 6 months, and 1 year. Photographs were taken for detailed facial evaluation. Patients were asked to fill a self-assessment questionnaire.Results:At the end of 6 months, improvements in mid face and lower face were reported in 93% patients by blinded reviewers and 85% patients found the results to be satisfactory. The same results were maintained at the end of 1 year.Conclusion:Our study showed that substantial results can be achieved in overall aesthetic improvement of sagging of mid face and lower face with this modality using intense focused ultrasound which utilizes delivering of treatment at a single focal depth.
