The retrograde mastoidectomy technique with canal wall reconstruction is described as a primary treatment for modality for cholesteatoma. This synthesis of canal wall up (CWU) and canal wall down (CWD) techniques involves removal of a portion of the canal wall for exposure and extirpation of the cholesteatoma, followed by reestablishment of the canal wall and ossicular chain during reconstruction. This technique is possible as a single stage in over 90% of cases, including children, with recurrence rates similar to CWD surgery, but with anatomic preservation similar to CWU. Recurrent disease occurred in 16% of cases reviewed in a longer term (8 year) follow-up study. Tobacco use was associated with a higher long-term complication rate.
采用外耳道壁重建的逆行乳突切除术技术被描述为胆脂瘤的一种主要治疗方式。这种外耳道壁上提（CWU）和外耳道壁下翻（CWD）技术的综合运用包括切除部分外耳道壁以暴露和摘除胆脂瘤，随后在重建过程中重建外耳道壁和听骨链。在超过90%的病例中，包括儿童，该技术可以作为一期手术完成，其复发率与CWD手术相似，但解剖结构保留情况与CWU相似。在一项长期（8年）随访研究中，16%的病例出现了复发性疾病。吸烟与较高的长期并发症发生率相关。
