19 patients had surgery for progressive [17] and/or symptomatic [2] posterior attic retraction pockets involving the facial recess. Exposition of the suprapyramidal region was obtained after endaural incision by thinning the posterior wall of the ear canal and removing the posterior-superior portion of the tympanic sulcus. This technique is less complicated than intact canal wall tympanoplasty with mastoidectomy. Yet gives similar functional results. After a mean follow-up of 20.3 months, we have observed no residual cholesteatoma and no recurrent retraction pockets. Unlike posterior tympanoplasty, this technique makes it possible to meticulously remove the osteitic bone invariably found in the facial recess when there is infection of the retraction pocket.
19例患者因累及面神经隐窝的进行性[17例]和/或有症状的[2例]后上鼓室回缩袋接受手术。经耳内切口，通过削薄外耳道后壁并切除鼓沟后上部分，显露锥上区域。该技术比完整外耳道壁鼓室成形术加乳突切除术的操作更简单。但功能效果相似。平均随访20.3个月后，我们未观察到残余胆脂瘤和复发性回缩袋。与后鼓室成形术不同，当回缩袋发生感染时，该技术能够细致地清除面神经隐窝中始终存在的骨质炎性病变。
