摘要
目的:探讨应用趾腓侧皮瓣修饰性再造拇指指腹缺损的手术方法及操作技巧。方法:2009年1月至2014年1月,对22例22指拇指指腹缺损的患者,应用同侧趾腓侧皮瓣游离移植修饰性再造拇指指腹缺损,其中采用趾-指动脉和趾-指静脉吻合18例,跖背动脉-桡动脉深支和跖背静脉-手背静脉吻合4例,神经修复均为指-趾神经吻合,供区皮肤缺损采用同侧腹股沟全厚皮片游离移植。结果:术后22例趾腓侧皮瓣游离移植均获成功,伤口一期愈合,无皮瓣坏死。随访6~12个月(平均7.6个月),皮瓣外形逼真,罗纹清晰,出汗、感觉恢复良好,两点分辨觉3.0~6.0 mm,平均4.2 mm。供区植皮完全成活,足部外形及功能无明显影响。结论:趾腓侧皮瓣是修饰性再造拇指指腹缺损的首选皮瓣,再造拇指指腹外形及功能接近正常。
Objective:To investigate the validity and the outcome of a new surgery method that utilizes lateral great toe flap to decoratively reconstruct the thumb pulp loss.Methods:From Jan.2009 to Jan. 2014 , 22 cases with unilateral thumb pulp defect were included, for whom, lateral great toe flap was de-ployed to reconstruct the thumb.Blood circulation was re-established by the anastomosis of the digital vessels of toes and fingers in 18 cases, the other 4 cases were conducted by a dorsal metatarsal artery and vein anastomosed to the deep branch of the radial artery and the dorsal metacarpal vein respectively; as for the nerve repair, toe-to-finger digital nerve anastomosis was performed.The donor sites were covered by full-thickness inguinal skin grafts.Results:All the 22 flaps survived without complications.With 6 to 12 months follow-up, the surviving fingers all presented aesthetically pleasant appearance with vivid loops and whorls.Normal functions like sweating were restored as well, and the two-point-discrimination ranged 3.0 to 6.0 mm (4.2 mm in average).The skin grafts to the donor sites healed uneventfully, the appearance and functions of the feet were unaffected.Conclusion: Lateral toe flap should be the first-line choice for reconstructing thumb defect, as it conveniently restores both functions and outlook.
