带蒂皮瓣修复口底缺损失败原因分析

目的 对11例口底缺损后皮瓣修复坏死原因进行分析。方法 收集56例带蒂肌皮瓣修复口底缺损，11例口底恶性肿瘤切除后即刻进行带蒂皮瓣修复，并进行比较分析。结果 比较5种带蒂皮瓣修复法，其成功率的顺序是：额瓣、胸大肌肌皮瓣、斜方肌肌皮瓣、胸锁乳突肌肌皮瓣、舌骨下肌群皮瓣。结论 皮瓣坏死有供区供血系统及口底区解剖结构上的原因，也有术者手术的主观原因，对口底缺损带蒂皮瓣修复失败原因要进行综合分析。

Unsuccess Cause Analysis of Pedunculated Flaps Reconstructed the Defect of Floor of the Mouth

Objective To analyze the reason of necrosis for pedunculated skin flaps repaired after floor of the mouth defect repair.Methods 56 cases of pedunclated-flaps restoring the floor of the mouth from 1996 to 2001 were reviewed, and pedunclated-flap repair was performed after operation in 11 cases suffering from malignant tumors in the floor of the mouth, and 5 kinds of pedunculated flaps were compared.Results Five kinds of pedunculated flaps were used to reconstruct the floor of the mouth defects. Its successful sequence was as following: forehead flap, pectoralis major myocutaneous flap, sternocleidomastoid flaps,trapezius myocutaneous flaps, and subhyoid flap.Conclusions Causes of those flaps necrosis might relate to furnishing blood with supplied-flaps region and structure of anatomy in received-flaps region, also it is related to operater's skill.So the reason of repair failure of skin flaps with pedicle needs comprehensive analysis.
