单蒂旋转拇指背侧逆行岛状皮瓣修复指端缺损

Dorsal thumb rotated single pedical reverse island flap repaired thumb tip defect

目的 探讨应用单蒂旋转拇指背侧逆行岛状皮瓣修复指端缺损的手术方法及临床疗效.方法 回顾性分析应用拇指背侧单蒂旋转逆行岛状皮瓣修复指端缺损49例患者的临床资料,其中桡背侧岛状皮瓣37例,尺背侧岛状皮瓣12例.结果 手术时间40~60 min,平均45 min.49例皮瓣均成活.2例术后1~2 d皮瓣颜色发紫、出现水泡,部分拆线后好转,水泡表皮形成干痂皮,去除痂皮后皮瓣血运良好,皮肤颜色正常.49例经3~24个月随访,皮瓣色泽、质地及皮肤弹性良好,外形满意,吻合神经皮瓣两点辨别觉6~9 mm,未吻合神经皮瓣两点辨别觉8~10 mm,拇指功能、外观恢复满意,恢复捏持功能.皮瓣供区功能及外观无影响.结论 单蒂旋转拇指背侧逆行岛状皮瓣,不损伤主要神经及动脉,血管蒂长,旋转弧度大,成活率高,手术操作简单易行,易于推广,疗效满意,是修复拇指指端缺损的理想方法之一.

Objective To evaluate the outcomes of thumb reconstruction with dorsal thumb rotated single pedicel reverse island flap.Methods 49 thumb-tip defects cases with dorsal thumb rotated single pedicel reverse island flap were analyzed retrospectively.37 dorsal thumb reverse island flap were performed,and 12 ulnar-dorsal reverse island flaps were performed.Results The operation time was 40-60 minutes.The mean time was 45 minutes.All 49 cases survived completely.The color of the flaps was purple,and blisters in the surface of the flaps after 1-2 days in 2 cases.After took out stitches partly,the blisters were dried and crusted,the color of the flaps with better blood circulation was normal.The follow-up period was 3-24 months,all thumbs had satisfactory appearances and functions.The two-point discrimination was 6-9mm in flaps inosculated with nerve,that was 8-10 mm in flaps inosculated without nerve.The color,texture and elasticity of flaps were excellent,and the donor sites had not been defected.Conclusion Dorsal thumb rotated single pedicel reverse island flap is a reliable option to restore function as well as appearance,long vascular pedicle with skin strap,wide rotation angle,high rate of survival.It avoided damages to the well-known arteries and nerves.It is a relatively facile procedure that can be applied toward resurfacing thumb tip defects.
