Facial nerve tumors can present as masses in the internal auditory canal or cerebellopontine angle and may mimic an acoustic neuroma. These tumors can occur in any segment of the nerve from the brain stem to the neuromuscular junction. Prior to the advent of computed tomography and magnetic resonance imaging with gadolinium, facial nerve tumors were often difficult to diagnose. Even with these modalities it may be difficult to distinguish preoperatively between an acoustic neuroma and a facial schwannoma. Particular signs and symptoms associated with facial nerve tumors (in the spasms, and a facial tic. These symptoms, combined with modem radiologic studies, should allow for more accurate diagnosis, patient counseling, and treatment. This report presents a series of 32 facial nerve tumors diagnosed and treated at The Otology Group from 1975 to 1992. Of these lesions, 12 (38%) were thought to be acoustic neuromas. Eighteen tumors were correctly identified preoperatively as facial nerve tumors. Two facial nerve tumors were found incidentally.
面神经肿瘤可表现为内耳道或桥小脑角的肿块，可能类似听神经瘤。这些肿瘤可发生于从脑干到神经肌肉接头的神经的任何节段。在计算机断层扫描和钆增强磁共振成像出现之前，面神经肿瘤常常难以诊断。即使有这些检查手段，术前也可能难以区分听神经瘤和面神经鞘瘤。与面神经肿瘤相关的特定体征和症状（如痉挛和面部抽搐）。这些症状，结合现代放射学检查，应能实现更准确的诊断、患者咨询和治疗。本报告介绍了1975年至1992年在耳科组诊断和治疗的一系列32例面神经肿瘤。在这些病变中，12例（38%）被认为是听神经瘤。18例肿瘤术前被正确诊断为面神经肿瘤。2例面神经肿瘤为偶然发现。
