利用残余耳垂修复累及耳廓的外耳道鳞状细胞癌术区缺损

Use of residual earlobe to repair auricular defect of external auditory canal squamous cell carcinoma

目的探讨累及耳廓的外耳道癌术区较大皮肤缺损的修复方法。方法分离残余耳垂前后皮肤使之成一扇形皮瓣,向前覆盖耳廓及颞部手术缺损区。结果残余耳垂扇形皮瓣成活良好,外耳道通畅,听力良好,手术创面修复满意,11例患者随访1年均无复发和转移。结论应用残余耳垂皮肤组织形成扇形皮瓣,修复累及耳廓的外耳道癌术区较大皮肤缺损效果好,具有临床推广价值。

OBJECTIVE To study the repair of large area skin defect in auricular meatus carcinoma. METHODS The front and back skin tissue of remnant earlobe was separated to form a fan-shaped flap. This flap was pulled forward to cover the auricular and tempora coloboma area of operation. RESULTS The fan-shaped flap of remnant earlobe survived well with satisfying external auditory canal patency and hearing results, the repair of coloboma area defect was satisfying. There was no recurrence and metastasis after one year follow- up in 11 cases. CONCLUSION Using the remnant earlobe fan-shaped flap to repair large area skin defect in auricular meatus carcinoma operation is satisfying and worthy of clinical recommendation.
