带股外侧皮神经的股前外侧皮瓣修复足背皮肤缺损

Repair of dorsal skin defects of the foot with nerved anterolateral thigh flap

目的探讨用带股外侧皮神经的股前外侧皮瓣修复足背皮肤缺损的效果。方法应用吻合血管的股前外侧皮瓣，同时用股外侧皮神经与腓浅神经吻合修复足背皮肤缺损38例。结果皮瓣全部存活。术后足背感觉2～4个月完全恢复，供区3～6个月逐渐恢复触、痛、温觉。38例随访4～18个月，平均9个月，皮瓣色泽、质地、外形功能均正常。结论带神经的股前外侧皮瓣，神经位置恒定，切取方便，术后皮瓣有感觉，耐磨，是修复足背大面积皮肤缺损的好方法。

Objective To discuss the use of anterolateral thigh flap for the repair of large defects of soft tissues in dorsum of the foot. Methods A total of 38 cases of dorsal skin defects of the foot was repaired with the anterolateral thigh flap containing the lateral femoral cutaneous nerves. Corresponding vessels and sensory nerves were anastomosed. Results The flaps survived in all the cases. The sensation in dorsum of the foot recovered completely within 2～4 months after operation and the touch, pain, and temperature sensation of the donor area recovered within 3～6 months after operation. Follow-up observations in the 38 cases for 4～18 months （mean, 9 months） showed flaps with normal color, texture, and appearance. Conclusions It is recommended to repair large - scale defects in dorsum of the foot with nerved anterolateral thigh flap.
