Abstract：
W-plasty is a very popular scar excisional revision technique. The core of the technique is to break up the scar margins into small triangular components, so as to cause light scattering and make the scar less noticeable. However, due to skin tension, facial incision scars tend to spread. Applying W-plasty alone cannot achieve the ideal repair effect of facial scars. In this study, we proposed a scar revision technique combined W-plasty with continuous tension-reduction (CTR) technique to improve the appearance of facial scars. Sixty patients with facial scar were comprised in this retrospective study. Scars were assessed independently using the scar scale before and at 12-month follow-up. Clinical results showed a significant difference in scar appearance between different groups at 12-month follow-up. Vancouver scar scale (VSS), visual analogue scale (VAS) scores, and patient satisfaction were significant better in W-plasty and CTR than other groups at 12-month follow-up. No severe complications were reported. The application of the tension offloading device provides an environment where the tension is continuously reduced, which could greatly decrease tension on the surgical incision. Combined with W-plasty, this technique could significantly improve the scar\'s aesthetic appearance.
摘要：
W成形术是一种非常流行的疤痕切除翻修技术。该技术的核心是将疤痕边缘分解成小的三角形组件，从而引起光散射，使疤痕不那么明显。然而,由于皮肤紧张，面部切口疤痕容易扩散。单纯应用W型修补术不能达到理想的面部瘢痕修复效果。在这项研究中,我们提出了一种将W-成形术与连续张力降低（CTR）技术相结合的疤痕翻修技术，以改善面部疤痕的外观。这项回顾性研究包括60例面部瘢痕患者。在12个月随访前和随访时，使用瘢痕量表独立评估瘢痕。临床结果表明，在12个月的随访中，不同组之间的瘢痕外观存在显着差异。温哥华疤痕量表（VSS），视觉模拟量表（VAS）评分，在12个月的随访中，W成形术和CTR的患者满意度明显优于其他组。无严重并发症报告。张力卸载装置的应用提供了张力不断降低的环境，这可以大大降低手术切口的张力。结合W-成形术，这种技术可以显著改善疤痕的美观。
