Cholesteatomas, classified as acquired or congenital, are non-neoplastic, keratinizing squamous epithelial lesions that can affect many different areas of the temporal bone. We present a case of a six-month-old female with chronic otorrhea who was found to have a congenital cholesteatoma originating from the Eustachian tube. Chronic pressure from cholesteatoma expansion turned the Eustachian tube into a large cavity approximately double the size of the middle ear space. This case was unusual not only in the location of the cholesteatoma but also in respect to the unusual presentation of chronic middle ear infection due to Eustachian tube obstruction.
胆脂瘤分为后天性或先天性，是非肿瘤性、角化性鳞状上皮病变，可累及颞骨的许多不同部位。我们报告一例6个月大慢性耳漏的女性病例，该患者被发现患有起源于咽鼓管的先天性胆脂瘤。胆脂瘤扩张产生的慢性压力使咽鼓管变成了一个大约是中耳腔两倍大小的大腔。该病例不仅在胆脂瘤的位置上不寻常，而且在因咽鼓管阻塞导致的慢性中耳感染的不寻常表现方面也不寻常。
