To determine the locations of congenital cholesteatomas and to elucidate the relationship between ossicular anomalies and congenital cholesteatomas, cholesteatomas from our patients and those reported in the Japanese literature were investigated. We analyzed 40 ears with congenital cholesteatomas (38 patients) experienced by us during the past 9 years. Our criteria of congenital cholesteatoma were as follows: 1. The tympanic membrane manifests neither retraction, perforation, nor granulation, 2. There is no continuity between the tympanic membrane and the matrix of a cholesteatoma. Twenty patients with past histories of otitis media were included. Thirty-three patients (87%) were males and 2 had bilateral congenital cholesteatomas. The ages of the patients ranged from 2 to 46 years (mean: 10.7). A survey of the Japanese literature revealed 55 additional cases of congenital cholesteatoma reported by others.
为了确定先天性胆脂瘤的位置，并阐明听骨链异常与先天性胆脂瘤之间的关系，我们对本院患者以及日本文献报道中的先天性胆脂瘤进行了研究。我们分析了过去9年中我们所诊治的40例（38名患者）先天性胆脂瘤病例。我们诊断先天性胆脂瘤的标准如下：1. 鼓膜无内陷、穿孔或肉芽；2. 鼓膜与胆脂瘤基质无连续性。其中包括20例有中耳炎病史的患者。33例（87%）为男性，2例为双侧先天性胆脂瘤。患者年龄范围为2至46岁（平均10.7岁）。对日本文献的调查显示，其他人还报道了另外55例先天性胆脂瘤病例。
