Abstract：
BACKGROUND: Thread-lifting (TL) is a minimally-invasive technique for facial rejuvenation, whereas liposuction is commonly used for facial contouring. This retrospective cohort study aims to introduce and evaluate a novel technique that combines liposuction and thread-lifting for mid-lower facial rejuvenation.
METHODS: Consecutive patients who underwent TL for mid-lower facial rejuvenation from May 2016 to May 2021 were divided into thread-lifting group (TL group) or thread-lifting plus liposuction group (TLL group) according to whether liposuction was performed adjunctively. The co-primary outcomes were the changes between the preoperative and 6-month postoperative Wrinkle Severity Rating Scale (WSRS) and Facial Aging Evaluation Scale (FAES).
RESULTS: A total of 185 patients (184 females) with an average age of 34.5±5.5 years were included. There were no significant differences in patients\' age, number of threads, and preoperative WSRS and FAES between the two groups. The TLL group (n = 128) had significantly lower postoperative WSRS (1.5±0.6 vs. 1.8±0.8, p<0.001) and FAES (2.5±1.4 vs. 3.8±2.1, p<0.001) than the TL group (n = 57). The decrease in WSRS (0.8±0.6 vs. 0.2±0.7, p<0.001) and FAES (2.7±1.3 vs. 1.6±1.6, p<0.001) were greater in the TLL group. Only 3.8% patients experienced slight side effects and totally recovered.
CONCLUSIONS: The combination of TL and liposuction is an effective and safe technique for simultaneous contour improvement and facial rejuvenation in middle-aged East Asian females.

摘要：
背景：提线（TL）是一种用于面部年轻化的微创技术，而吸脂术通常用于面部轮廓。这项回顾性队列研究旨在介绍和评估一种新颖的技术，该技术结合了吸脂术和提线术以实现中下面部年轻化。
方法：2016年5月至2021年5月连续行下颌骨修复术的患者，根据是否辅助吸脂术分为提线组（TL组）或提线加吸脂组（TLL组）。共同主要结果为术前和术后6个月皱纹严重程度评定量表（WSRS）和面部老化评估量表（FAES）之间的变化。
结果：共纳入185例患者（184例女性），平均年龄34.5±5.5岁。患者年龄无显著差异，线程数,术前WSRS和FAES.TLL组（n=128）术后WSRS明显降低（1.5±0.6vs.1.8±0.8，p<0.001）和FAES（2.5±1.4vs.3.8±2.1,p<0.001)比TL组(n=57)。WSRS的减少(0.8±0.6vs.0.2±0.7，p<0.001）和FAES（2.7±1.3vs.TLL组的1.6±1.6，p<0.001）更大。只有3.8％的患者出现轻微的副作用并完全康复。
结论：TL和吸脂术的结合是一种有效且安全的技术，可同时改善中年东亚女性的轮廓和面部年轻化。
