Objective To evaluate the clinical efficacy of different SMAS (superficial muscle aponeurosis) suspension points in minimally invasive facial lift surgery. Methods A total of 80 patients undergoing minimally invasive facial lift surgery at our hospital from May 2024 to August 2025 were divided into an observation group (40 cases) and a control group (40 cases) based on suspension point selection. The observation group received a multi-target precision suspension technique (temporal region + anterior inferior zygomatic arch + mid-mandibular border), while the control group underwent traditional single-target suspension (temporal region only). Preoperative and postoperative (6 months) facial aesthetics, skin function, patient satisfaction, and complication rates were compared using statistical analysis. Results At 6 months post-surgery, the observation group demonstrated significantly better outcomes in facial laxity improvement rate, nasolabial fold depth reduction, and mandibular border definition score (P<0.05). The observation group also showed higher skin elasticity coefficient (P<0.05). Although the complication rate in the observation group was lower, the difference was not statistically significant (P>0.05). Conclusion The multi-target precision suspension technique in minimally invasive SMAS lift surgery provides comprehensive improvement in facial laxity, enhances skin function and aesthetics, and demonstrates good safety. This approach is worthy of clinical promotion and application.
