Although much has been written about the central nervous system infectious complications of otitis media, little has been written about intracranial extension of cholesteatoma in chronic otitis media. The records of 13 patients from the House Ear Clinic with chronic otitis media and cholesteatoma extending into the middle fossa and/or the posterior fossa are reviewed. Preoperatively, symptoms included hearing loss (100%), dizziness (61%), facial weakness (46%), and headache (31%). All 13 patients had previously undergone at least one mastoidectomy procedure for removal of cholesteatoma. The neurotologic approaches used included the middle fossa, translabyrinthine, and transcochlear operations. Eradication of cholesteatoma was accomplished with one neurotologic procedure, in 11 of 13 patients with two neurotologic procedures in one patient, and without surgery in one patient. Audiologic findings and facial nerve results are discussed.
尽管关于中耳炎的中枢神经系统感染并发症已有诸多著述，但关于慢性中耳炎胆脂瘤颅内扩展的论述却很少。回顾了豪斯耳科诊所13例慢性中耳炎合并胆脂瘤扩展至中颅窝和/或后颅窝患者的病历。术前症状包括听力丧失（100%）、头晕（61%）、面部无力（46%）和头痛（31%）。所有13例患者此前均至少接受过一次乳突切除术以清除胆脂瘤。所采用的神经耳科手术方法包括中颅窝手术、经迷路手术和经耳蜗手术。13例患者中有11例通过一次神经耳科手术实现了胆脂瘤的根除，1例患者通过两次神经耳科手术根除，1例患者未进行手术。文中讨论了听力学检查结果及面神经情况。
