| 摘 要: 研究职业性噪声聋患者的听觉稳态反应(ASSR) 阈值及纯音测试(PTA) 听阈的关系, 为提高诊断职业性噪声聋的准确性以及鉴别伪聋提供科学依据｡方法 选取117 例诊断为职业性噪声聋的患者, 分别对其进行ASSR 与PTA 两种检查, 测试不同频率的阈值｡结果 PTA 与ASSR 阈值之差在0. 5 kHz､1 kHz､2 kHz､4 kHz 的中位数依次为6､1､-2､4 dB HL, 差异有统计学意义(P<0. 01); ASSR 与PTA 阈值在0. 5 kHz､1 kHz､2 kHz､4 kHz相关系数依次为0. 46､0. 75､0. 82､0. 83, 可以认为二者有较好的直线相关关系(P<0. 05)｡结论 听觉稳态反应阈与纯音听阈有良好的相关性, 且阈值比较接近, 可以作为职业性噪声聋患者客观听力评估的方法之一｡ |

| Abstract: To study the correlations between thresholds of auditory steady⁃state responses (ASSR) and pure
tone audiometry ( PTA) in patients with occupational noise⁃induced hearing loss, thereby provide a scientific basis for improving the accuracy of the diagnosis of occupational noise⁃induced deafness and the identification of pseudo deaf Methods One hundred and seventeen patients diagnosed as occupational noise⁃induced hearing loss were selected and two examinations of ASSR and PTA were carried out, respectively, then, the thresholds at different frequencies were obtained.The PTA and ASSR thresholds for each frequency were obtained Results The results showed that the median values of the differences between PTA and ASSR thresholds were 6 dB HL､1 dB HL､-2 dB HL and 4 dB HL at 0. 5 kHz､1 kHz､2 kHz and 4 kHz, respectively,the differences were obviously statistically significant (P<0. 01). The correlation coefficient of the thresholds from two tests at 0.5､1､2 and 4 kHz were 0.46､0.75､0.82 and 0.83, respectively, which showed good linear correlation relationship (P<0. 05). Conclusion The results suggested that the ASSR thresholds were well⁃correlated with that of PTA, ASSR could be used as one of the objective methods for hearing evaluation. |
