Infants admitted to neonatal intensive care units have a higher incidence of significant congenital hearing loss. We classified audiologic diagnoses and follow-up in infants who had been admitted to our neonatal intensive care unit.
We included all infants admitted to the neonatal intensive care unit at Sophia Children's Hospital between 2004 and 2009 who had been referred for auditory brainstem response measurement after failing neonatal hearing screening with automated auditory brainstem response. We retrospectively analyzed the results of auditory brainstem response measurement.
Between 2004 and 2009 3316 infants admitted to our neonatal intensive care unit had neonatal hearing screening. 103 infants failed neonatal hearing screening: 46 girls and 57 boys. After first auditory brainstem response measurement we found 18% had normal hearing or a minimal hearing loss. The remainder had a type of hearing loss, distributed as follows: 15% conductive, 32% symmetric sensorineural, 14% asymmetric sensorineural, and 21% absent auditory brainstem responses. Repeated auditory brainstem response measurement showed a shift in hearing outcome. The main difference was an improvement from symmetric sensorineural hearing loss to normal hearing. However, in a small percentage of children, the hearing deteriorated.
As many as 58% of infants in this high-risk population who failed the neonatal hearing screening were diagnosed with sensorineural hearing loss or absent auditory brainstem responses. An initial overestimation of sensorineural hearing loss of about 10% was seen at first auditory brainstem response measurement. This may be partially explained by a conductive component that has resolved. Finally, in a small percentage of children the hearing deteriorated.
入住新生儿重症监护病房的婴儿发生严重先天性听力损失的几率更高。我们对入住我院新生儿重症监护病房的婴儿的听力诊断及随访情况进行了分类。
我们纳入了2004年至2009年间入住索菲亚儿童医院新生儿重症监护病房、在新生儿听力筛查中自动听性脑干反应筛查失败后被转诊进行听性脑干反应测量的所有婴儿。我们回顾性分析了听性脑干反应测量的结果。
2004年至2009年间，3316名入住我院新生儿重症监护病房的婴儿接受了新生儿听力筛查。103名婴儿新生儿听力筛查失败，其中46名女孩，57名男孩。首次听性脑干反应测量后，我们发现18%的婴儿听力正常或有轻微听力损失。其余婴儿存在某种类型的听力损失，分布如下：15%为传导性，32%为对称性感音神经性，14%为非对称性感音神经性，21%为听性脑干反应消失。重复听性脑干反应测量显示听力结果有所变化。主要差异是从对称性感音神经性听力损失改善为听力正常。然而，一小部分儿童的听力恶化了。
在这个高危人群中，多达58%的新生儿听力筛查失败的婴儿被诊断为感音神经性听力损失或听性脑干反应消失。在首次听性脑干反应测量时，发现感音神经性听力损失最初被高估了约10%。这可能部分是由已解决的传导性成分所致。最后，一小部分儿童的听力恶化了。
