Osteomas as well as exostoses of the internal auditory canal are rare, benign, usually slow-growing lesions. The most common localizations of these temporal bone lesions are the mastoid cortex and the external auditory canal. A rare case is reported of bilateral osseous stenosis of the internal auditory canal, in the absence of clinical (auditory, vestibular and facial nerve) symptoms. In the absence of auditory, vestibular and/or facial nerve symptoms, long-term follow-up should be assessed; surgical intervention may be warranted only if symptoms are present.
骨瘤和外耳道骨瘤是罕见的良性、生长缓慢的病变。这些颞骨病变最常见的部位是乳突皮质和外耳道。报道了一例罕见的双侧内听道骨性狭窄病例，无临床（听觉、前庭和面神经）症状。在无听觉、前庭和/或面神经症状的情况下，应评估长期随访；只有出现症状时才需要手术干预。
