The purpose of this study was to investigate the effectiveness of the combined treatment of acupotomy subcision and Nanofat grafting in depressed scars.
A single-center retrospective analysis was performed on 32 patients with moderate to severe depressed facial scars treated between November 2020 and April 2023. The treatment involved acupotomy subcutaneous scrape, followed by Nanofat injection. Clinical assessments included measurement of scar concavity using a 3D camera, the Patient Observer Scar Assessment Scale (POSAS), and a skin analysis system to evaluate collagen and elastin levels.
The study found a significant reduction in scar concavity from a mean of -0.90 ± 0.44 mm pre-treatment to -0.10 ± 0.18mm six months post-treatment. POSAS scores showed substantial improvements in scar esthetics at 6 months post-operation. There was also a significant increase in skin elasticity and a decrease in skin collagen levels following treatment.
The combined application of acupotomy subcision and Nanofat grafting was effective in reducing the depression of depressed scars, leading to significant improvements in scar appearance and patient satisfaction. This approach offers a minimally invasive and effective treatment option for patients with depressed scars.

本研究旨在探讨针刀松解术联合纳米脂肪移植治疗凹陷性瘢痕的有效性。
对2020年11月至2023年4月期间治疗的32例中重度面部凹陷性瘢痕患者进行单中心回顾性分析。治疗包括针刀皮下刮除，然后进行纳米脂肪注射。临床评估包括使用3D相机测量瘢痕凹陷度、患者观察者瘢痕评估量表（POSAS）以及评估胶原蛋白和弹性蛋白水平的皮肤分析系统。
研究发现瘢痕凹陷度从治疗前的平均-0.90±0.44毫米显著降低至治疗后6个月的-0.10±0.18毫米。POSAS评分显示术后6个月瘢痕美观度有显著改善。治疗后皮肤弹性也显著增加，皮肤胶原蛋白水平降低。
针刀松解术联合纳米脂肪移植在减轻凹陷性瘢痕凹陷方面有效，可显著改善瘢痕外观和患者满意度。该方法为凹陷性瘢痕患者提供了一种微创且有效的治疗选择。
