Different etiologies are associated with different audiologic features, and auditory steady-state responses might serve as an objective measure for estimating behavioral thresholds.Īuditory neuropathy is a challenging clinical disorder accounting for ~10% of cases of sensorineural hearing loss (SNHL) in children 1, 2, 3. In conclusion, comprehensive assessments can provide etiological clues in ~75% of the children with auditory neuropathy. In patients with different etiologies or pathological sites, moderate to strong correlations (Pearson’s r = 0.51–0.83) were observed between behavioral thresholds and auditory steady-state response thresholds. Patients with acquired auditory neuropathy presented hearing loss earlier (odds ratio, 10.2 95% confidence interval, 2.2–47.4), whereas patients with genetic auditory neuropathy had higher presence rate of distortion product otoacoustic emissions (odds ratio, 10.7 95% confidence interval, 1.3–85.4). The most common causes of acquired and genetic auditory neuropathy were prematurity and OTOF mutations, respectively. Etiologically, 48 (47.5%), 16 (15.8%), 11 (10.9%), and 26 (25.7%) children were categorized as having acquired, genetic, cochlear nerve deficiency-related, and indefinite auditory neuropathy, respectively. This study used an integrative patient-history, audiologic, genetic, and imaging-based approach to investigate the etiologies and audiologic features of 101 children with auditory neuropathy.

Due to diverse etiologies and clinical features, the management is often challenging. Auditory neuropathy is an important entity in childhood sensorineural hearing loss.
