The prevalence of auditory neuropathy/dyssynchrony (AN/AD) is not exactly known. We retrospectively analysed the prevalence of this condition among 135 infants who failed a neonatal screening. Hearing screening was performed by automated auditory brainstem responses (AABR). Unilateral presence of click-evoked oto-acoustic emissions with absent auditory brainstem responses was found in 4 infants. Magnetic resonance imaging of the posterior fossa showed an aplasia/hypoplasia of the ipsilateral cochlear nerve in these 4 cases. The prevalence of AN/AD was 19% in infants with confirmed hearing loss. Our findings underscore the role of AABR in neonatal hearing screening.
听觉神经病/失同步（AN/AD）的患病率尚不完全清楚。我们回顾性分析了135例新生儿听力筛查未通过的婴儿中这种疾病的患病率。听力筛查采用自动听性脑干反应（AABR）进行。4例婴儿出现单侧咔嗒声诱发耳声发射而听性脑干反应缺失。这4例患者的后颅窝磁共振成像显示同侧耳蜗神经发育不全/发育不良。确诊听力损失的婴儿中AN/AD的患病率为19%。我们的研究结果强调了AABR在新生儿听力筛查中的作用。
