The auditory brain stem response and the blink reflex were studied in 35 handicapped children in order to evaluate brain stem function. The auditory brain stem response and the blink reflex were abnormal in 20 and 16 cases, respectively. Of these, 14 had both auditory brain stem response and blink reflex abnormalities. The prevalence of auditory brain stem response and blink reflex abnormalities was high in severely handicapped children with difficulty in chewing or swallowing. The blink reflex was abnormal in four of 32 sides with a normal auditory brain stem response and 15 of 23 sides with an abnormal auditory brain stem response threshold, which reflects hearing loss or brain stem dysfunction. We conclude that the combined application of these two noninvasive tests is useful not only to delineate the extent of brain stem lesions but also to determine whether or not patients with an abnormal auditory brain stem response threshold have brain stem dysfunction.
为评估脑干功能，对35名残疾儿童进行了听觉脑干反应和瞬目反射研究。听觉脑干反应异常的有20例，瞬目反射异常的有16例。其中，14例同时存在听觉脑干反应和瞬目反射异常。在咀嚼或吞咽困难的重度残疾儿童中，听觉脑干反应和瞬目反射异常的发生率较高。在听觉脑干反应正常的32侧中，有4侧瞬目反射异常；在听觉脑干反应阈值异常（提示听力损失或脑干功能障碍）的23侧中，有15侧瞬目反射异常。我们得出结论，这两项非侵入性检查联合应用不仅有助于明确脑干病变的范围，还能确定听觉脑干反应阈值异常的患者是否存在脑干功能障碍。
