We report a patient with a cavernous haemangioma of the internal auditory canal (IAC). A 47-year-old man presented with a left profound hearing loss and a left facial palsy that had progressed over 5 years. With a preoperative diagnosis of acoustic or facial nerve neurinoma, the tumour was removed totally by a translabyrinthine approach. Intraoperatively, the tumour appeared red; it compressed the facial and cochlear nerves, and adhered to the vestibular nerve. The tumour was diagnosed as a cavernous haemangioma upon histologic and immunohistochemical examination. No recurrence of tumour occurred, but hearing loss and left facial palsy persisted. Although cavernous haemangiomas of the IAC is found in small size less than 10 mm, they often cause severe hearing loss and facial palsy. Our patient had no improvement of facial palsy, but many reports describe recovery of facial nerve function.
我们报告一例患有内耳道海绵状血管瘤的患者。一名47岁男性，出现左侧严重听力损失和左侧面部麻痹，这种情况持续了5年。术前诊断为听神经瘤或面神经神经鞘瘤，通过经迷路入路将肿瘤完全切除。术中，肿瘤呈红色；它压迫面神经和耳蜗神经，并与前庭神经粘连。经组织学和免疫组化检查，肿瘤被诊断为海绵状血管瘤。肿瘤未复发，但听力损失和左侧面部麻痹仍然存在。虽然小于10毫米的小尺寸内耳道海绵状血管瘤也有发现，但它们常导致严重的听力损失和面部麻痹。我们的患者面部麻痹没有改善，但许多报告描述了面神经功能的恢复。
