A full-thickness skin graft (FTSG) is useful for covering small skin and soft tissue defects. In this paper, we suggest FTSG in consideration of the relaxed skin tension line (RSTL) concept for scar quality improvement since FTSG has disadvantages, including contour irregularities and mismatches of color and texture. We conducted a retrospective chart review of twenty-one patients with skin cancer on the face who underwent wide excision and FTSG by a single surgeon from October 2013 to July 2019. Twenty-one patients with skin cancer on the face were divided into RSTL-matched and RSTL-unmatched groups, and FTSG was performed. Each group was subjected to scar assessment three months after surgery. Observer assessment was performed by five independent observers using the observer component of the patient and observer scar assessment scale (POSAS) and Vancouver scar scale (VSS). Our results indicate that there were significant differences between the RSTL-matched and RSTL-unmatched groups in the VSS and POSAS components. In addition, the RSTL-matched group showed a natural appearance with surrounding tissue in the dynamic animation phase compared to the unmatched group. RSTL-matched FTSG can be an attractive option for face skin and soft tissue defect coverage. (An earlier version of this paper has been presented at the International Conference on PRS Korea 2020.)

根据周围松弛的皮肤张力线进行全层皮肤移植改善面部缺陷覆盖的疤痕质量：一项回顾性比较研究

全层皮肤移植 (FTSG) 可用于覆盖小的皮肤和软组织缺损。在本文中，我们建议 FTSG 考虑到用于改善疤痕质量的松弛皮肤张力线 (RSTL) 概念，因为 FTSG 有缺点，包括轮廓不规则和颜色和纹理不匹配。我们对 2013 年 10 月至 2019 年 7 月接受单一外科医生广泛切除和 FTSG 的 21 名面部皮肤癌患者进行了回顾性图表审查。将 21 名面部皮肤癌患者分为 RSTL 匹配和 RSTL 不匹配的组，并进行了 FTSG。每组在手术后三个月进行疤痕评估。观察者评估由五名独立观察者使用患者和观察者疤痕评估量表 (POSAS) 和温哥华疤痕量表 (VSS) 的观察者部分进行。我们的结果表明，在 VSS 和 POSAS 组件中，RSTL 匹配组和 RSTL 不匹配组之间存在显着差异。此外，与未匹配组相比，RSTL匹配组在动态动画阶段显示出与周围组织的自然外观。RSTL 匹配的 FTSG 可以成为面部皮肤和软组织缺损覆盖的有吸引力的选择。（本文的早期版本已在 2020 年 PRS 韩国国际会议上发表。）此外，与未匹配组相比，RSTL匹配组在动态动画阶段显示出与周围组织的自然外观。RSTL 匹配的 FTSG 可以成为面部皮肤和软组织缺损覆盖的有吸引力的选择。（本文的早期版本已在 2020 年 PRS 韩国国际会议上发表。）此外，与未匹配组相比，RSTL匹配组在动态动画阶段显示出与周围组织的自然外观。RSTL 匹配的 FTSG 可以成为面部皮肤和软组织缺损覆盖的有吸引力的选择。（本文的早期版本已在 2020 年 PRS 韩国国际会议上发表。）
