摘　　要：目的评价干反应对前庭性眩晕的诊断价值.方法对32例前庭性眩晕病人进行听脑干反应检查.结果听脑干反应异常的有20例,异常率为62.5%.其中Ⅰ波波形异常或消失者有5例、Ⅲ波波形异常或消失者有4例、Ⅴ波波形异常或消失者有1例,Ⅰ波PL延长4例,Ⅲ波PL延长4例,Ⅴ波IPL延长12例,I～ⅢIPL延长1例,Ⅲ～VIPL延长4例,I～VIPL延长1例,双侧I～V波的IPL差值大于0.4ms者4例.I～Ⅲ/ⅢVIPL的比值<1者4例.结论ABR检查对鉴别周围性眩晕和中枢性眩晕有一定的参考价值.Objective To explore the diagnostic value of ABR in the diagnosis of vestibular system vertigo. Methods ABRs were determined in 32 patients with vestibular system vertigo. Results ABRs were abnormal in 20 patients, the abnormality rate was 62.5%. Wave I was abnormal or disappeared in 5 cases. Wave Ⅲ was abnormal or disappeared in 4 cases. Wave V was abnormal or disappeared in 1 case. PL of Wave Ⅰ prolonged in 4 cases. PL of Wave Ⅲ prolonged in 4 cases. PL of Wave Ⅴ prolonged in 12 cases. IPL of waves Ⅰ Ⅲ prolonged in 1 case, IPL of waves Ⅲ - Ⅴ prolonged in 4 cases, IPL of waves Ⅰ - Ⅴ prolonged in 1 case. ILD of bilateral wave Ⅰ - Ⅴ was more than 0. 4 ms in 4 cases. Ⅰ-Ⅲ / Ⅲ - Ⅴ IPL 〈 1 in 4 cases. Conclusion ABR may be of important value in differentiating vestibular peripheral and central vertigo.
