本文主要讨论经乳突凿开保留外耳道后壁,开放后鼓室处理胆脂瘤作鼓室成形的优点及有关问题。乳突术式包括开放式、封闭式和乳突填充三种,在处理耳胆脂瘤时采用开放或封闭式乳突手术方面存在着争论,作者倾向于保留外耳道壁完整的封闭式手术。这种手术有三个目的:①清除胆脂瘤,②保持或恢复功能,③尽可能保持或恢复解剖形态。本文分析了1965～1974年间所作1024例胆脂瘤手术,其中88.1%采用保存耳道壁
This article mainly discusses the advantages and related issues of transposition of the posterior wall of the external auditory canal after the mastoidids have been excavated to open the posterior wall of the cholesteatoma. There are three types of mastoid surgery, open, closed, and mastoid filling. There are controversies regarding the use of open or closed mastoid surgery in the treatment of ear cholesteatoma. The authors tend to preserve the complete closed surgery of the external auditory canal wall. This surgery has three purposes: ① clear cholesteatoma, ② maintain or restore function, ③ as much as possible to maintain or restore anatomical morphology. This article analyzes 1024 cases of cholesteatoma surgery between 1965 and 1974, of which 88.1% were preserved ear canal wall
