摘要:目的 总结改良胸大肌肌皮瓣修复头颈肿瘤手术组织缺损的临床疗效。方法　回顾性地总结我科2004年6月1日～2008年6月31日间，15例应用改良胸大肌肌皮瓣修复头颈肿瘤手术巨大组织缺损，其中12例经锁骨下隧道转移。手术均为Ⅰ期修复，皮瓣面积为5cm×6cm～10cm×15cm。结果 肌皮瓣全部成活，2例发生咽瘘， 1例肌皮瓣远端部分坏死，均经换药后愈合。结论　胸大肌肌皮瓣具有丰富的血液供应，优良的组织量，修复操作简单，应用广泛，特别适用于头颈部肿瘤扩大切除术后巨大组织缺损的修复，我们通过保留上1/3-1/2胸大肌及锁骨下隧道转移改良，充分发挥了胸大肌肌皮瓣的优越性。

Abstract Objective：Summary the clinical efficacy on repair of tissue defects in head and neck tumors with modified pectoralis major myocutaneous flap. Method：A retrospective summary of 15 cases of application of modified pectoralis major muscle flap for head and neck tumors large tissue defect in our department between June 1, 2006 to January 31, 2010.(12 cases transfer via subclavicular pedicle ).All the operation wereⅠ-stage repair size of flaps ranged from 5cm×6cm to 10cm×15cm. Result：Muscle flaps all survived in 12 cases, 2 cases of pharyngocutaneous fistula occurred. 1 cases of distal part of the muscle flap necrosis cases were healed by changing dressing. Conclusion：Pectoralis major muscle rich blood supply, excellent organizational capacity, simple operating so that it can be applied in many cases，especially for repair of tissu
