前臂桡侧-掌长肌腱复合瓣在唇颊部缺损修复中的应用

目的：探讨前臂桡侧-掌长肌腱复合瓣在唇颊部缺损修复中的应用价值，并对临床手术经验进行初步总结。方法：应用前臂桡侧-掌长肌腱复合瓣对5例唇颊部缺损患者进行手术修复，掌长肌腱与残余口轮匝肌可共同维持唇颊部形态和功能，对折的前臂皮瓣则可同时修复皮肤与黏膜缺损。术后定期随访，最短随访时间20个月。结果：5例游离复合瓣移植后均获得成活，成活率100％，在术后6个月，复合瓣外观形态较好；术后10-12个月，患者能很好地进行开闭口、咀嚼等运动。结论：前臂桡侧-掌长肌腱复合瓣修复唇颊部缺损，形态和功能均令人满意。

Lip and cheek reconstruction with composite radial forearm-palmaris longus tendon flap

PURPOSE:To investigate the value of functional reconstruction of the lip and cheek with composite radial forearm-palmaris longus tendon flap.METHODS:Composite radial forearm-palmaris longus tendon flap was used in 5 cases,the flap was folded for repair of oral mucosa and external skin,palmaris longus tendon and the remaining orbicularis muscles were sutured so that oral contour and function could be achieved.All the patients were followed up for at least 20 months.RESULTS:All 5 composite flaps survived well postoperatively.6 months after reconstruction,the patients had good oral and facial contour;10-12 months after surgery,the dynamic function of mouth opening and closing as well as mastication was recovered to normal.CONLUSION:Composite radial forearm-palmaris longus tendon flap is reliable and thus recommended for functional reconstruction of the lip and cheek.
