颏神经血管蒂V-Y岛状推进瓣功能性修复下唇部分缺损

Mental neurovascuinr V-Y island advancement flap in functional reconstruction of partial lower lip defect

目的探讨下唇部分缺损的功能修复方法。方法对7例下唇癌患者做手术切除，形成的唇全厚缺损（缺损长度为下唇1／3至2／3）用颏神经血管束为蒂的颏部V-Y岛状推进瓣修复。结果颏神经血管蒂V-Y岛状推进瓣全部成活，术后3个月至1年随访，无肿瘤复发，唇外观良好，修复的下唇肌功能和感觉正常。结论颏神经血管蒂V-Y岛状推进瓣是下唇部分缺损功能性修复的理想方法。

Objective To investigate the functional reconstruction technique for partial lower lip defects.Methods 7 patients with lower lip cancer （3 cases of basal cell carcinoma, 2 cases squamous ceil carcinoma and 2 cases papillary carcinoma） underwent excision. The full-thickness lower lip defects were one-third to two-third of the total lower lip length. All the defects were reconstructed with V-Y island advancement flaps based on the mental neurovascular bundle. Results There was no flap loss. No recurrence was observed during the follow-up period of 3 months to one year. Both the aesthetic appearance, muscle function and sensation of the reconstructed lower lip were satisfactory. Conclusions Mental neurovascular V-Y island advancement flap is an ideal method for functional repair of patial lower lip defect.
