摘　　要：目的:探讨瞬目反射(BR)及脑干听觉诱发电位(BAEP)在听神经瘤(acoustic neuroma)检测中的诊断价值。方法:对78例确诊为听神经瘤患者分别进行BR和BAEP检测。结果:78例听神经瘤患者患侧BR异常76例,异常率为97%,患侧BAEP异常77例,异常率为99%。在19例小型肿瘤组(瘤直径<2cm)BR异常率为84%,BAEP异常率为95%。在59例中大型肿瘤组(2~4cm以上)中,患侧BAEP各波或Ⅲ、Ⅴ波消失44例,在此44例中,BR表现为传出型损害12例,传入型损害10例,混合型损害22例。结论:BR与BAEP对听神经瘤的诊断有很高的敏感性,二者联合检测更易于早期发现听神经瘤的亚临床病灶,有助于听神经瘤的早期诊断。Objective:To explore the value of blink reflex(BR)and brainstem auditory evoked potential(BAEP)in the diagnosis of acoustic neuroma(AN).Methods:Forty normal persons and 78 AN patients were examined with BR and BAEP respectively.Results:In 78 patients with AN the abnormality rate of BR was 97% and the abnormality rate of BAEP was 99% respectively,in which the abnormality rate of BR was 84% and the abnormality rate of BAEP was 95% respectively in 19 cases with small neuromas;in 59 cases with medum and large n...
