摘要:

［目的］探讨未通过听力筛查新生儿听力诊断方法。［方法］ 用短音诱发脑干听觉诱发电位（click-auditory brainstem responses，click-ABR）和多频稳态听觉诱发电位（auditory steady-state responses，ASSR）及鼓室声导抗技术对听力筛查未通过新生儿进行听力学评估，均在出生6个月内明确诊断，并进行听力学跟踪随访至1~2岁。［结果］310例听力筛查未通过者于出生6个月内诊断为听力正常者260例，占未通过听力筛查的83.9%；click-ABR听力评估结果异常43例，占未通过听力筛查的13.9%；click-ABR听力评估结果正常，ASSR检测异常者7例，占未通过听力筛查的2.3%；鼓室声导抗测试异常10例，占未通过听力筛查的3.2%。［结论］对未通过听力筛查新生儿需进行click-ABR和ASSR及鼓室声导抗检测及动态随诊观察，从而给出准确的诊断。

Abstract:

［Objective］To investigate the hearing diagnostic method for newborns failing in the hearing screening. ［Methods］Click-auditory brainstem responses (Click-ABR), auditory steady-state responses (ASSR )and tympanometry were used to test newborns failing in the hearing screening from 40 days to 6 months, then we follow up them until 1~2 years old. ［Results］ Two hundred and sixty infants were diagnosed with normal hearing in 6 months old, the rate was 83.9% of 310 infants who failed hearing screening; 43 infants were diagnosed with abnormal hearing by Click-ABR test (13.9%); 7 infants were diagnosed with normal results by Click-ABR test while abnormal results by ASSR test(2.3%); 10 infants were diagnosed with abnormal results by tympanometric test (3.2%). ［Conclusion］In order to make an accurate diagnosis, protect infants from dysphasia, it is necessary for infants failing in the hearing screening to have tests of click-ABR, ASSR, tympanometry and be followed up until 1~2 years old.
