Auditory Steady-State Responses (ASSR) are being recognized as a promising technique in the assessment of hearing in children.
To investigate the agreement level between results obtained from ASSR and click-ABR in a group of children with sensorineural hearing loss, in order to study the clinical applicability of this technique to evaluate the hearing status in young children.
clinical prospective with a cross-sectional cohort.
15 children aged between two and 36 months and with diagnosis of sensorineural hearing loss. The correlation between the responses of the two tests was evaluated by intraclass correlation coefficient and McNemar test comparing the probability of responses in both tests.
The correlation coefficients were: 0.70; 0.64; 0.49; 0.69; 0.63 and 0.68 respectively for frequencies of 1, 2, 4, 1-2, 2-4 and 1-2-4kHz. In McNemar test p = 0.000, indicating that the probability of obtaining responses in both tests was not equal, but greater for the ASSR.
we found good agreement between the techniques among the four frequencies evaluated, suggesting that both tests may be complementary. However, the ASSR was able to obtain additional information in cases of severe and profound hearing losses, adding important data to the management of these children, providing greater accuracy to the audiological diagnosis.
听觉稳态反应（ASSR）在儿童听力评估中被认为是一种很有前途的技术。
研究一组感音神经性听力损失儿童的 ASSR 和短声听觉脑干反应（ABR）结果之间的一致性水平，以研究该技术在评估婴幼儿听力状况方面的临床适用性。
临床前瞻性、横断面队列研究。
15 名年龄在 2 至 36 个月之间、诊断为感音神经性听力损失的儿童。通过组内相关系数和 McNemar 检验评估两种测试的反应相关性，比较两种测试的反应概率。
四种频率（1、2、4、1-2、2-4 和 1-2-4kHz）的相关系数分别为 0.70、0.64、0.49、0.69、0.63 和 0.68。McNemar 检验 p=0.000，表明两种测试的反应概率不相等，但 ASSR 的反应概率更大。
我们发现评估的四个频率之间的技术有很好的一致性，表明两种测试可能是互补的。然而，在严重和极重度听力损失的情况下，ASSR 能够获得额外的信息，为这些儿童的管理提供了重要的数据，对听力学诊断的准确性有较大的提升。
