因为面神经和位听神经相毗邻,故压迫面神经的血管有可能影响位听神经,产生听觉前庭机能的异常。已有报告,在半面痉挛患者,患侧镫骨肌反射、听觉脑干反应的Ⅲ、Ⅴ波潜伏期较健侧异常。位听神经神经血管压迫的临床特点是搏动性耳鸣和眩晕发作。对27例听力正常的半面痉挛患者,研究其左右两侧的听觉脑干反应,包括各波的绝对潜
Because the facial nerve and the bit adjacent to the auditory nerve, so oppressing the facial nerve blood vessels may affect the position of the auditory nerve, resulting in abnormal auditory auditory function. It has been reported in patients with hemifacial spasm, ipsilateral stapedius reflex, auditory brainstem response Ⅲ, Ⅴ wave latency than the contralateral abnormal. A clinical auditory nerve neurovascular compression is characterized by pulsatile tinnitus and vertigo attacks. 27 cases of normal hearing half hemifacial spasm, the study on both sides of the auditory brainstem response, including the absolute potential of the wave
