Abstract：
BACKGROUND: Face-lifting surgeries were once common among individuals over 60 years old due to skin laxity, but recent trends favor thread lifting in this age group. Understanding dynamic changes in facial anatomy during postural shifts is essential.
METHODS: Fresh cadaver studies have demonstrated the passage of threads through the superficial musculoaponeurotic system (SMAS) layer, confirming the efficacy of the technique. Proper insertion depth targeting SMAS repositioning, rather than superficial skin layers, is crucial.
RESULTS: The natural movement of tissues secured by thread (N-Cog and N-Fix, N-Finders Inc., Korea) insertion results in lifting effects. However, complications may arise if threads affect deeper facial muscles, leading to discomfort. Fibrous septa play a significant role in guiding thread placement, with different densities influencing thread maneuverability and tissue response during lifting.
CONCLUSIONS: Procedures targeting SMAS repositioning using threads aim to maintain the new position of relocated tissues. Understanding structural variations in facial regions informs thread selection and placement. Aligning threads with tissue movement and the intended SMAS layer positioning is vital to prevent complications. Balancing thread insertion depth and tissue traction is critical for successful outcomes. Modern thread lifting techniques prioritize SMAS repositioning, enhancing lifting effects while ensuring procedure safety and efficacy.

摘要：
背景：由于皮肤松弛，整容手术曾经在60岁以上的人群中很常见，但是最近的趋势更倾向于这个年龄段的线程提升。了解姿势转变过程中面部解剖结构的动态变化至关重要。
方法：新鲜的尸体研究表明，线穿过浅表肌肉和肌腱膜系统（SMAS）层，确认该技术的有效性。针对SMAS重新定位的适当插入深度，而不是皮肤表层，至关重要。
结果：由线（N-Cog和N-Fix，N-FindersInc.,韩国)插入导致提升效应。然而,如果螺纹影响面部深层肌肉，可能会出现并发症，导致不适。纤维状隔片在引导丝线放置中起着重要作用，在提升过程中，不同的密度会影响螺纹的可操作性和组织反应。
结论：针对使用螺纹的SMAS重新定位的程序旨在维持重新定位组织的新位置。了解面部区域的结构变化可通知线程选择和放置。使线与组织运动和预期的SMAS层定位对准对于防止并发症至关重要。平衡螺纹插入深度和组织牵引对于成功的结果至关重要。现代螺纹提升技术优先考虑SMAS重新定位，增强提升效果，同时确保程序的安全性和有效性。
