To evaluate the canal wall up (CWU) technique combined with mastoid obliteration used in cholesteatoma surgery from the aspects of safety and function.
Retrospective chart review. Information was extracted from a medical database and complementary data from patient files and audiograms were collected and recorded retrospectively.
A tertiary-stage hospital and a secondary-stage hospital. Surgeons of various levels of experience.
Data from a consecutive group of 230 primary operations for cholesteatoma surgery using CWU with obliteration employing the combined approach tympanoplasty (CAT) technique, from January 1994 to December 2009 were analyzed.
In 90% of the ears, the anatomy was normalized with an intact ear drum. The frequency of residual cholesteatoma was 1% and the frequency of recurrent cholesteatoma 8%. Hearing was improved one year postoperatively and remained improved three years postoperatively. No patient suffered a total hearing loss.
CWU procedure comprising CAT with obliteration of the mastoid is a safe surgical method with a low frequency of residual and recurrent disease and a good hearing preservation.
从安全性和功能方面评估胆脂瘤手术中使用的上鼓室开放（CWU）技术联合乳突根治术。
回顾性病历审查。从医学数据库中提取信息，并回顾性收集和记录来自患者病历及听力图的补充数据。
一家三级医院和一家二级医院。不同经验水平的外科医生。
分析了1994年1月至2009年12月期间连续230例采用CWU联合乳突根治术及联合进路鼓室成形术（CAT）技术进行的胆脂瘤一期手术的数据。
90%的耳内解剖结构恢复正常，鼓膜完整。残余胆脂瘤的发生率为1%，复发性胆脂瘤的发生率为8%。术后一年听力有所改善，术后三年仍保持改善。无患者出现全聋。
包括采用CAT联合乳突根治术的CWU手术是一种安全的手术方法，残余和复发性疾病发生率低，听力保留良好。
