A battery of subjective and electrophysiologic auditory and vestibular tests were administered to 22 patients with neurologically confirmed brain-stem lesions to investigate the interrelationships between the test results. Acoustic-reflex and simultaneous midplane binaural loudness-balance abnormalities were related to N2 and N3 abnormalities on the brain-stem evoked-response measures. Unilateral abnormalities in low-redundancy speech tests, prolonged auditory reaction times, and reduced loudness growth on the alternate binaural loudness-balance test were related to ipsilateral N4 abnormalities or contralateral N5 abnormalities on the brain-stem evoked-response measures.
对22例经神经学确诊为脑干病变的患者进行了一系列主观及电生理听觉和前庭测试，以研究测试结果之间的相互关系。听觉反射和同时出现的中平面双耳响度平衡异常与脑干诱发反应测量中的N2和N3异常有关。低冗余言语测试中的单侧异常、听觉反应时间延长以及交替双耳响度平衡测试中响度增长降低与脑干诱发反应测量中的同侧N4异常或对侧N5异常有关。
