简要总结
A non-randomized, evaluator-blinded study was conducted to observe the changes in the face before and after facial rejuvenation using microfocused ultrasound. The efficacy of microfocused ultrasound in facial rejuvenation was evaluated using standardized photographs in conjunction with a dermatological testing system and to explore the effects of microfocused ultrasound on the function of the skin.
详细描述
Primary efficacy endpoints:Utilizing the 3D Life Viz mini system for standardized photo modeling enables the comparison and identification of enhancements in treatment outcomes. This research utilized standardized photo modeling to record the facial and mandibular conditions of patients, capturing images both before and after treatment (immediately post-operation and at 7, 30, 90, 180，270 and 360 days). The detection of improvements in treatment effects was then achieved through pairwise comparisons of the modeled data derived from these photographs;Secondary efficacy endpoints: Global Aesthetic Improvement Scale, patient satisfaction scores, Digital Visual Analog Scale
