Radical surgery for congenital cholesteatoma leaves the patient, usually a child, with an ear that requires care for life. At the Otologic Medical Group, the intact canal wall technique has been used for many patients with cholesteatoma. To determine results of this management in the treatment of congenital cholesteatoma, we reviewed records of all patients treated between 1974 and 1985. Forty-two ears were studied in 41 patients. A closed middle-ear space was achieved in all cases, and an intact canal wall was maintained in 41 (98%). Follow-up averaged 4.3 years. Of the 41 cases with serviceable hearing before surgery, 28 (68%) had postoperative hearing within 10 dB of the best preoperative bone conduction threshold. Thirty-eight of the 41 achieved a final hearing result within 20 dB of the best bone conduction threshold.
先天性胆脂瘤根治性手术会使患者（通常是儿童）的耳朵需要终生护理。在耳科医疗集团，完整外耳道壁技术已应用于许多胆脂瘤患者。为了确定这种治疗方法在先天性胆脂瘤治疗中的效果，我们回顾了1974年至1985年间所有接受治疗患者的记录。对41例患者的42只耳朵进行了研究。所有病例均实现了中耳腔封闭，41只耳朵（98%）保持了完整的外耳道壁。平均随访4.3年。在术前听力尚可的41例病例中，28例（68%）术后听力与术前最佳骨导阈值相差在10 dB以内。41例中有38例最终听力结果与最佳骨导阈值相差在20 dB以内。
