Although the thread-lifting technique for sagging faces has become more common and popular, medical literature evaluating its effects is scarce. Studies on its long-term prognosis are particularly uncommon.
One hundred individuals who had previously undergone insoluble thread-lifting were retrospectively investigated. Photos in frontal and oblique views from the first and last visits were evaluated by six female individuals by guessing the patients' ages. The mean guessed age was defined as the apparent age, and the difference between the real and apparent ages was defined as the youth value. The difference between the youth values before and after the thread-lift was defined as the rejuvenation effect and analyzed in relation to the time since the operation, the number of threads used and the number of thread-lift operations performed.
The rejuvenation effect decreased over the first year after the operation, but showed an increasing trend thereafter. The rejuvenation effect increased with the number of threads used and the number of thread-lift operations performed.
The insoluble thread-lifting technique appears to be associated with both early and late effects. The rejuvenation effect appeared to decrease during the first year, but increased thereafter. A multicenter trial is necessary to confirm these findings.
尽管用于面部松弛的埋线提升技术已变得更为常见和流行，但评估其效果的医学文献却很匮乏。关于其长期预后的研究尤其少见。
对100名先前接受过不可溶线埋线提升的个体进行回顾性研究。由6名女性通过猜测患者年龄来评估首次和末次就诊时的正面及斜位照片。平均猜测年龄被定义为表观年龄，实际年龄与表观年龄的差值被定义为年轻值。埋线提升前后年轻值的差值被定义为回春效果，并针对术后时间、使用的线数及进行的埋线提升手术次数进行分析。
回春效果在术后第一年下降，但此后呈上升趋势。回春效果随使用的线数及进行的埋线提升手术次数增加而增加。
不可溶线埋线提升技术似乎与早期和晚期效果均有关联。回春效果在第一年似乎下降，但此后增加。需要进行多中心试验来证实这些发现。
