目的探讨噪声性听力损伤的听觉脑干反应(ABR)特点,为职业性噪声聋的诊断提供依据。方法对76例职业接噪工人和19例非接噪工人分别进行中耳分析、耳声发射、ABR检查,结果用SPSS 13.0软件统计分析其相关性。结果 1对照组各波引出率均高于噪声组,对照组Ⅰ~Ⅴ波引出率分别为68.4%~100%,噪声组Ⅰ~Ⅴ波引出率分别为49.3%~86.8%,两组差异均有统计学意义;2噪声组Ⅴ波潜伏期为5.61 ms,对照组Ⅴ波潜伏期为5.42 ms,两组差异有统计学意义;3噪声组不同中、内耳情况Ⅰ、Ⅱ、Ⅲ、Ⅴ波引出率存在差异,差异有统计学意义;4噪声组不同中、内耳情况各波潜伏期及潜伏间期差异无统计学意义。结论 1噪声可引起ABRⅠ~Ⅴ波的单一缺失或联合缺失;2噪声引起潜伏期的延长以Ⅴ波最早出现;3接噪工人中、内耳是否正常对ABR各波引出率有影响,中、内耳越正常,引出率越高,反之越低;4接噪工人中、内耳是否正常对ABR各波的潜伏期及潜伏间期影响不大。 Objective To investigate the characteristics of auditory brainstem response (ABR) in noise-induced hearing impairment and provide the basis for the diagnosis of occupational noise-induced hearing loss. Methods Totally 76 cases of occupational noise workers and 19 cases of non-noise workers were subjected to middle ear analysis, otoacoustic emission and ABR examination respectively. The results were statistically analyzed by SPSS 13.0 software. Results In the control group, the lead-out rate of each wave was higher than that of the noise group. The lead rates of Ⅰ-Ⅴ wave in the control group were 68.4% -100%, and the lead rates of Ⅰ-Ⅴ wave in the noise group were 49.3% -86.8% There was a statistically significant difference between the two groups; the noise wave group Ⅴ wave latency was 5.61 ms, the control group Ⅴ wave latency was 5.42 ms, the difference between the two groups was statistically significant; 3 noise group in the inner ear situation Ⅰ, Ⅱ, Ⅲ, Ⅴ wave lead-out rate There was a significant difference between the two groups in the noise group. There was no significant difference in latency and latency of each wave in the inner ear. Conclusion 1 Noise can cause a single deletion or combined deletion of ABRⅠ-Ⅴ waves; 2-noise causes the extension of latency to occur first Ⅴ wave; 3 of the noise-exposed workers, whether the inner ear is normal or not affects the ABR wave extraction rate, Normal, the higher the lead rate, and vice versa lower; 4 workers exposed to noise, the inner ear is normal ABR wave latency and latency is not affected.
