近20年对大胆脂瘤究竟是采用开放或封闭、保留耳道壁抑或除去耳道壁术式始终未解决。保留耳道壁重建术包括计划性二期手术可免除术腔,其解剖情况对听力及术后护理有利,但术后并发症多;开放术式可估价胆脂瘤清除情况,远较听力及耳道自洁力的好处为重要。亦可临时部分或全部除去耳道壁,以后再重置或修复之,或以软组织缩小乳突腔。此法具有上述二者优点,但术后难侦查乳突腔及上鼓室残余病变。作者对三种方法作回顾性观察: 保留耳道壁、完整耳道壁鼓室成形术组:435耳,术后临床诊断复发胆脂瘤(缩进囊袋)为

Preservation of the ear canal wall reconstruction, including the planned phase two surgery can be exempt from surgery, the anatomy of hearing and postoperative care is beneficial, but postoperative complications; open surgery to evaluate the clearance of cholesteatoma, far more than hearing and The benefits of ear canal self-cleaning are important.
