Idiopathic facial nerve paralysis is believed by some to represent one aspect of a polyneuropathy. Conventional audiologic tests have not demonstrated involvement of the auditory portion of the eighth cranial nerve in this disorder. A case history is given of a patient with this disorder and an associated abnormal auditory brain stem response (ABR). Our study involved onetime evaluations of 17 patients with idiopathic facial nerve paralysis of varying durations. Each examination included clinical presentation and history, an audiogram, acoustic reflex, and ABR. Another patient had abnormal acoustic reflex test results ("unibox" pattern) suggestive of a brain stem lesion. On reexamination concurrent recovery of the paralysis and acoustic reflex was demonstrated. No auditory system disturbances secondary to the paralysis were detectable by ABR in this survey. The concurrent recovery of the "unibox" acoustic reflex and the facial paralysis suggests the association of a brain stem lesion with idiopathic facial nerve paralysis in this case.
一些人认为特发性面神经麻痹是多神经病的一个表现方面。传统听力学测试未显示该疾病累及第八颅神经的听觉部分。本文给出了一名患有该疾病且伴有异常听觉脑干反应（ABR）患者的病例史。我们的研究对17例病程各异的特发性面神经麻痹患者进行了一次性评估。每次检查包括临床表现和病史、听力图、声反射和ABR。另一名患者的声反射测试结果异常（“单盒”模式），提示脑干病变。再次检查时，证实麻痹和声反射同时恢复。在本次调查中，ABR未检测到继发于麻痹的听觉系统干扰。“单盒”声反射与面神经麻痹同时恢复，提示该病例中脑干病变与特发性面神经麻痹有关。
