测定正常人20例ABR的正常值。测试350例患者的ABR,其中听阈测定244例,用于客观测定婴幼儿及不合作成人的听阈,鉴別语言障碍的原因,器质性聋抑功能性聋。诊断中枢病变28例,对桥小脑角肿瘤,脑干肿瘤、多发性硬化有定位诊断意义。鉴別耳蜗抑蜗后病变78例。双耳Ⅴ波潜伏期差,尤其是双耳Ⅰ～Ⅴ波间期差是诊断的重要参数,应提高Ⅰ波检出率,同时记录耳蜗电图,有助于诊断率的提高。
Normal 20 cases of normal ABR determination. The ABR was measured in 350 patients, of which 244 were used for the determination of hearing threshold, which were used to objectively measure the threshold of hearing loss in infants and non-adults, identify the causes of language disturbance, and deafness and deafness. Diagnosis of central lesions in 28 cases, the cerebellopontine angle of the tumor, brain stem tumors, multiple sclerosis positioning diagnostic significance. 78 cases of cochlear and post-nodal lesions were identified. The latency of Ⅴ wave in both ears is poor, especially the interphase Ⅰ ~ Ⅴ wave interval is an important parameter in diagnosis. The detection rate of Ⅰ wave should be increased and the electrocochleogram should be recorded at the same time, which helps to improve the diagnosis rate.
