[摘要]目的：探讨外弧形切口在皮肤软组织扩张术中的应用及对烧伤后瘢痕患儿皮肤扩张情况、美观满意度的影响。方法：选取2020年9月-2022年6月笔者医院收治的80例烧伤后瘢痕患儿作为研究对象，采用随机数字表法分为对照组(40例)和观察组(40例)。对照组采用传统术式直切口进行手术置入扩张器，观察组采用外弧形切口进行手术置入扩张器。比较两组围术期指标、皮肤扩张情况、瘢痕修复效果及患者美观满意度。结果：观察组术中出血量少于对照组，术后24 h疼痛评分低于对照组，创面愈合时间及皮肤血运恢复时间均短于对照组，瘢痕修复率高于对照组(均P<0.05)。观察组扩张完成时间短于对照组，即时回缩率低于对照组，皮肤扩张率高于对照组(均P<0.05)。皮瓣移植术后3个月，两组瘢痕血管分布、柔软度、厚度、色泽评分均降低，且观察组低于对照组(P<0.05)。随访1年后，观察组瘢痕修复总有效率为95.00%，高于对照组的77.50%(P<0.05)，观察组瘢痕修复美观满意度高于对照组(P<0.05)。结论：采用外弧形切口进行皮肤软组织扩张术在儿童烧伤后瘢痕整形中的修复效果优于传统术式直切口，可显著改善患儿皮肤扩张情况及瘢痕状态，值得临床推荐。

    Abstract： Objective" To explore the application of external curved incision in skin and soft tissue expansion surgery and its impact on the skin expansion and aesthetic satisfaction of children with scars after burns. Methods" 80 children with scars after burns admitted to the author's Hospital from September 2020 to June 2022 were selected as the research subjects. They were divided into the control group (40 cases) and the observation group (40 cases) by random number table method. The control group underwent traditional straight incision for surgical implantation of expanders ......
