[摘要]目的：探究股前外侧穿支皮瓣游离移植修复四肢皮肤缺损的临床疗效。方法：选取2018年6月-2023年9月笔者医院收治的98例四肢皮肤缺损患者进行研究，患者皮肤软组织缺损面积为6.12 cm×9.34 cm～15.23 cm×32.74 cm，均行股前外侧穿支皮瓣游离移植修复，皮瓣切取面积为7.35 cm×10.34 cm～17.63 cm×34.49 cm。观察手术疗效、术后损伤部位功能、感觉恢复情况及术后并发症发生情况。结果：术后随访6个月，皮瓣全部成活，通过皮瓣供血优良度判断，术后优86例，良12例；DASH评分为18～24分，平均(21.46±1.27)分，下肢功能LEFS量表评分为36～52分，平均(43.97±5.57)分。79例患者感觉功能恢复至S3，其余恢复保护性感觉，两点辨别觉为5.3～8.2 mm。供区皮肤饱满红润，无感觉功能障碍。出现并发症共4例(4.08%)，其中，感染3例，经抗感染治疗后得到控制；皮瓣边缘坏死1例，经换药或皮瓣移植后愈合，未发生血管危象、感觉障碍等情况。结论：股前外侧穿支皮瓣游离移植修复四肢皮肤缺损疗效显著，能够改善缺损部位的外观和功能，恢复损伤肢体感觉，并发症少，是一种较为理想的选择。
