Objective

We aimed to evaluate whether electrophysiological auditory thresholds (EATs) before 3 month of age, as assessed by the auditory brainstem responses (ABR) test and the auditory steady state responses (ASSR) test, can predict hearing outcome at 3 years of age among children born with congenital cytomegalovirus (cCMV) infection.

Study design

Audiological assessment was performed before 3 months of age, and every 6 months thereafter until 3 years of age, in a population of 63 children (126 ears). EATs before 3 months of age and at 3 years of age were compared.

Result

No ear with an EAT of ≤30 dBHL (i.e. normal hearing) before 3 months of age showed worsening EATs at 3 years of age.

Conclusion

An EAT of ≤30 dBHL obtained by ABR and ASSR tests before 3 months of age is predictive of a normal hearing at 3 years of age in children born with cCMV.

先天性巨细胞病毒感染和听力学随访：3 个月前的电生理听觉阈值作为 3 岁听力结果的预测指标。

客观的

我们旨在评估通过听觉脑干反应 (ABR) 测试和听觉稳态反应 (ASSR) 测试评估的 3 个月前的电生理听觉阈值 (EAT) 是否可以预测 3 岁儿童的听力结果出生时患有先天性巨细胞病毒 (cCMV) 感染。

学习规划

在 63 名儿童（126 只耳朵）中，在 3 个月大之前进行听力评估，之后每 6 个月进行一次，直到 3 岁。比较 3 个月前和 3 岁时的 EAT。

结果

3 个月前 EAT ≤ 30 dBHL（即正常听力）的耳朵没有在 3 岁时出现恶化的 EAT。

结论

在 3 个月前通过 ABR 和 ASSR 测试获得的 EAT ≤30 dBHL 预示着 cCMV 出生的儿童在 3 岁时听力正常。
