Abstract

The ABR interaural latency difference (ILD) from 15 patients with brain stem lesions was compared to the ILDs from patients with VIIIth nerve tumors, cochlear pathology, and a normal control group. All patients in the study had to meet the criteria of bilaterally symmetrical hearing for pure-tone thresholds in order to offset the effect of hearing loss on the ILD. Although the ILDs for the brain stem lesion group were larger than for the cochlear or normal groups, they were significantly smaller than for the VIIIth nerve tumor group. It appears that the ILD is not as sensitive a measure for detecting brain stem involvement as VIIIth nerve tumors.

摘要

将15例脑干病变患者的听性脑干反应（ABR）双耳潜伏期差（ILD）与听神经瘤患者、耳蜗病变患者及正常对照组的ILD进行了比较。研究中的所有患者必须满足纯音阈值双侧对称的标准，以抵消听力损失对ILD的影响。尽管脑干病变组的ILD大于耳蜗组或正常组，但明显小于听神经瘤组。看来，ILD作为检测脑干受累情况的指标不如检测听神经瘤敏感。
