职业性噪声聋患者听觉诱发电位的初步研究

摘要

Objective To study the correlation between auditor}1 evoked potential (AEP) and occupational noise deaf. Methods 45 cases of patients with occupational noise deaf (24 case with mild deafness, 21 cases with moderate deafness) and 25 individuals with normal healing (control group) were detected by pure tone audiometry (PTA), auditory sieady-siate evoked responses (ASSR), bralnstem auditor)" evoked potentials (BAEP) and 40 Hz auditory event-related potentials (40 Hz AEP) test. The tests results of the two groups were compared. Results There were significant difference in PTA, ASSR, BAEP and 40 Hz AEP test results between the control group and mild, moderate deafness group (P ＜ 0.05); PTA was positively correlated with AEP reacting values (r - 0.722, 0.670, 0.835). Conclusion ASSR, BAEP, 40 Hz AEP tests can provide objective and impartial basis for the diagnosis of occupational noise deaf.%目的 探讨听觉诱发电位与噪声性聋易感性的关系.方法 使用纯音测听(PTA)、多频稳态诱发电位(ASSR)、脑干诱发电位(BAEP)、40 Hz听觉诱发电位(40 Hz AEP)检测45例职业性噪声聋患者(轻度聋24例,中度聋21例)和25例听力正常者(对照组),对PTA结果与ASSR、BAEP、40 Hz AEP反应阈检测结果进行对比研究.结果 对照组PTA、ASSR、BAEP、40 Hz AEP值与轻度和中度噪声聋比较,差异均有统计学意义(均P<0.05),FTA阈值与各听觉诱发电位反应值均存在正相关关系(r=0.722、0.670、0.835).结论 ASSR、BAEP、40 Hz AEP检测能为职业性听力损伤的诊断提供客观、公正的依据.
