A series of 58 patients with idiopathic facial paralysis were studied to determine if a concomitant cochlear or eight nerve auditory dysfunction could be identified with traditional audiologic tests. Results indicated that only those patients with a facial nerve lesion, proximal to the stapedius branch, experienced reduced tolerance for loud sounds, reduction of speech discrimination at high-intensity levels, and abnormal loudness growth. Such findings suggest that changes in auditory function, accompanying facial nerve paralysis, are a mechanical effect due to absence of stapedial action. Site of lesion tests in this sample failed to demonstrate eighth nerve dysfunction and, thus, does not support a theory of polyneuropathy that involves the auditory nerve.
对58例特发性面神经麻痹患者进行了一系列研究，以确定能否通过传统听力测试识别出同时存在的耳蜗或听神经听觉功能障碍。结果表明，只有那些面神经病变位于镫骨肌支近端的患者，对大声的耐受性降低，高强度水平下言语辨别力下降，以及响度增长异常。这些发现表明，面神经麻痹伴随的听觉功能变化是由于镫骨肌活动缺失导致的机械效应。该样本中的病变部位测试未能证实听神经功能障碍，因此不支持涉及听神经的多神经病理论。
