To evaluate the hypothesis of central nervous system involvement in Bell's palsy, the auditory brain-stem responses (ABR) of 32 patients were studied. In 14 (43.7%) of these patients ABR abnormalities were found. In each case the ABR deviation suggested prolonged brain-stem conduction time, independent of the side or severity of the paralysis. Site of lesion tests in this sample failed to demonstrate eighth nerve dysfunction and, thus, does not support a theory of a polyneuropathy that involves the auditory nerve.
为评估贝尔麻痹患者中枢神经系统受累的假说，对32例患者的听觉脑干反应（ABR）进行了研究。其中14例（43.7%）患者存在ABR异常。在每种情况下，ABR偏差提示脑干传导时间延长，与面瘫的侧别或严重程度无关。该样本中的病变部位测试未能证实第八神经功能障碍，因此不支持涉及听神经的多发性神经病理论。
