A case of aural cholesteatoma extending into the middle cranial fossa is presented. The cholesteatoma appears to have recurred in an ear in which a radical mastoidectomy had been performed more than 40 years earlier. The patient complained only of a vague sensation of heat in the head and did not manifest distinct neurologic signs or symptoms. The cholesteatoma was removed through an extended endaural approach. Extension of aural cholesteatoma beyond the confines of the temporal bone appears to be quite unusual.
本文报道了一例胆脂瘤型中耳炎侵犯中颅窝的病例。该胆脂瘤似乎在40多年前已行根治性乳突切除术的耳内复发。患者仅主诉头部有模糊的热感，未表现出明显的神经体征或症状。通过扩大的耳道入路切除了胆脂瘤。胆脂瘤型中耳炎超出颞骨范围的情况似乎相当罕见。
