Abstract

Using clicks with varying interstimulus intervals and coherent tone-bursts, early components of the auditory evoked potential (brain stem responses) were studied in four patients with confirmed acoustic neuroma. Abnormalities in responses appeared with shorter interstimulus intervals and with tone-bursts delivered monaurally to the involved ear; bilateral alterations occurred in one patient with brain stem displacement. The results indicate that BSR can provide a stable, independent, noninvasive measure of auditory nerve function useful in the early detection of acoustic neuroma. The results contribute to the understanding of the so-called human FFR.

摘要

利用具有不同刺激间隔的点击声和相干短纯音，对4例确诊为听神经瘤的患者的听觉诱发电位（脑干反应）的早期成分进行了研究。当刺激间隔较短以及单耳向患耳传递短纯音时，反应出现异常；1例伴有脑干移位的患者出现双侧改变。结果表明，脑干反应能够提供一种稳定、独立、无创的听神经功能测量方法，有助于听神经瘤的早期检测。这些结果有助于对所谓的人类频率跟随反应的理解。
