To investigate the surgical treatment of cholesteatoma of the middle ear. A retrospective analysis of patients from June 2013 to July 2016 diagnosed as cholesteatoma. 137 ears were divided into A group (retaining part of the external auditory canal posterior wall with epitympanoplasty in soft wall reconstruction for 75 ears) and B group (canal wall down mastoidotympanoplasty for 62 ears). the extent and damage of cholesteatoma were observed, comparing the time of dry ear and epithelial postoperative, the incidence of complications such as dizziness and hearing changes. compared with B group, the postoperative dry ear time, epithelial time and hearing improvement in the A group were obviously improved, and the incidence of vertigo after operation was decreased, and the anatomical and physiological functions of the external auditory canal were protected. The technique of retaining part of the external auditory canal posterior wall with epitympanoplasty in soft wall reconstruction is conductive to the removal of lesions and normal anatomical and physiological protection to external auditory canal, can prevent the forming of the abstraction pocket effectively and the recurrence of cholesteatoma, has clinical and practical value.
探讨中耳胆脂瘤的外科治疗方法。回顾性分析2013年6月至2016年7月诊断为胆脂瘤的患者。137耳分为A组（保留部分外耳道后壁并进行上鼓室成形术软壁重建75耳）和B组（开放式乳突鼓室成形术62耳）。观察胆脂瘤的范围及损害情况，比较术后干耳时间、上皮化时间，以及头晕、听力变化等并发症的发生率。与B组相比，A组术后干耳时间、上皮化时间及听力改善情况明显好转，术后眩晕发生率降低，外耳道的解剖及生理功能得到保护。保留部分外耳道后壁并进行上鼓室成形术软壁重建技术有利于病变清除及对外耳道正常解剖生理的保护，能有效防止术腔上皮袋形成及胆脂瘤复发，具有临床实用价值。
