对胆脂瘤的手术方法经历了这样的发展过程:从预防并发症到改善听力;从除去外耳道后壁的开放式手术到保存后壁的鼓室成形术式。这类手术有着各种名称,一般常简称为CAT(Combined approach tympanoplasty)。CAT术式之优点为术后几能保持正常形态,但术后也可发生显著变化,其中尤以因受此种变化的影响而复发胆脂瘤的问题,目前正引起国外的重视和研究。作者报告1962年以来15年间经手术治疗的1044侧中
The surgical approach to cholesteatoma has undergone such a progression from preventing complications to improving hearing; from open surgery that removes the posterior wall of the external auditory canal to tympanoplasty that preserves the posterior wall. This type of surgery has a variety of names, often abbreviated as CAT (Combined approach tympanoplasty). The advantages of CAT surgery are that it can maintain its normal shape after operation, but it may also change significantly after operation. Especially the problem of recurrent cholesteatoma due to such changes is now arousing more attention and research abroad. The authors report 1044 sides surgically treated during the 15 years since 1962
