Abstract
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.Entities:
