Resumen

Objectives: 1.Categorize the inducement of facial overfilled syndrome（FOS). 2.Introduce a new treatment method of FOS. 3.Evaluate the clinical outcomes and safety of the study device and surgical procedure. Introduction: In Asia, facial overfilled syndrome (FOS) can arise from iatrogenic causes involving the excessive use of filling materials, as well as physiological causes such as adipose tissue hypertrophy type, age-related type, and lacuna type. This study aimed to demonstrate the safety and effectiveness of plasma radiofrequency-assisted microsuction (PRFAMS) for improving the appearance of FOS induced by various causes. Materials / method: PRFAMS was performed on 84 anatomical regions of 37 female patients (including 12 with physiological causes, 6 with hyaluronic acid causes, and 19 with fat causes), aged between 20 and 50 years (mean, 35.9 years), who had FOS. Demographic and surgical data were collected retrospectively. Preoperative and postoperative photographs were taken, and satisfaction interviews were conducted at least six months after surgery. Results: All patients underwent the operation successfully under local or intravenous anesthesia. Only four anatomic regions showed noticeable asymmetry post-surgery requiring a secondary operation. Additionally, five patients with longer edema periods demonstrated substantial improvement after more than five weeks. No cases of skin necrosis, thermal injury or other serious complications related to the study device or procedure were reported. Ultimately, all patients expressed satisfaction with their outcomes. Conclusion: The PRFAMS technique is a safe and effective method for treating FOS induced by various causes,while minimizing complications and ensuring high patient satisfaction.
