足趾移植再造拇手指术后指腹外形改进方法的探讨

目的 探讨以第2、3足趾移植再造拇、手指术后指腹短粗外形的改进方法.方法 对33例、39指不同指别的第2、3足趾移植再造术后的指腹,采用一侧和双侧皮肤及皮下组织部分切除缩小指腹.或将术中切下的皮肤及皮下组织做成筋膜蒂皮瓣转移至中节指掌侧,以增粗中节指节的周径.同时对几种方法进行同顾性的总结和探讨. 结果 33例39指修整的指腹皮肤无坏死,转移皮瓣血供好,术后指腹外形明显平坦,中节指周径有较明显增粗,效果满意.1例中节指掌侧进行游离皮片移植拟减轻指腹屈曲和增加中节指周径的方法效果不明显. 结论 应用对第2、3足趾移植再造拇手指术后指腹侧方切除部分皮肤及皮下组织的方法能够明显改善足趾趾腹移植到手指后的外形,与手指指腹外形更加接近.手术方法简单,效果可靠,对再造指指腹感觉及血供无影响.

Revisional surgery for improving outward appearance of reconstructed digit in toe-to-hand transfer

Objective To present some revision surgery for correcting short and bulky outward appearance of reconstructed finger pulp in toe-to-hand transfer. Methods Since Sep. 1998 to Dec. 2006,in a series of 33 patients, 39 fingers had been reconstructed with 2nd toe. In order to change the shape of bulbous distal toe segment into a normal tapering fingertip, revisional operations had been designed, i.e. (1)Excision of bulky skin and excessive soft tissue from one or both sides of the finger pulp. (2)Transfer and inlaid the excised lateral soft tissue flap to the central constricting part of the finger pulp. (3)Full thickness skin graft to palmar central narrow part of toe pulp. 4. Rotational transfer of local lateral "L" shape flap. Results All the patients healed by first intention with no skin necrosis occurred. The bulbous rectangular shaped toe pulp were corrected and outward appearance were much improved in most cases. Though the outward appearance in one simple skin graft case was not satisfactory in correcting flexion deformity of distal segment and increased its circumference. Conclusion In toe-to-hand transfer, the distal segment of reconstructed finger often shown to have an bulbous toe pulp appearance, which may bring psychological burden to the patient and their relatives. Simple revisional surgery recommended here may yield favorable improvement.
