Seven primary tumours of the vestibule and inner ear are described, six schwannomas and one traumatic fibroma. Schwannomas in this situation may occur as sporadic tumours, or may be a feature of neurofibromatosis type 2 (NF-2). In the latter condition they may occur in isolation or in association with, but separate from, schwannomas arising in the internal meatus. Direct extension into the vestibule of an intrameatal vestibular schwannoma is well reported, but extension of an intravestibular tumour into the internal meatus is not described. Traumatic fibromas of the vestibule are rare and the trigger could be an attack of labyrinthitis. Intravestibular tumours, although rare, are likely to be diagnosed with increasing frequency with the widespread use of MR imaging.
本文描述了7例前庭和内耳原发性肿瘤，其中6例为神经鞘瘤，1例为创伤性纤维瘤。这种情况下的神经鞘瘤可能是散发性肿瘤，也可能是2型神经纤维瘤病（NF-2）的特征之一。在后一种情况下，它们可能单独出现，或与内耳道神经鞘瘤同时出现但相互独立。内耳道前庭神经鞘瘤直接延伸至前庭已有充分报道，但前庭内肿瘤延伸至内耳道的情况尚未见描述。前庭创伤性纤维瘤罕见，其诱因可能是迷路炎发作。前庭内肿瘤虽然罕见，但随着磁共振成像（MR）的广泛应用，其诊断频率可能会增加。
