OBJECTIVE: To evaluate hearing-impaired children and other users of hearing aids (HA) in order to investigate the existence of auditory neuropathy spectrum disorder (ANSD). MATERIALS AND METHODS: This prospective andanalytical study comprised 15 children (30 ears), aged between 10-12 years, with bilateral sensorineural hearing loss, whovisited a Hearing Rehabilitation Center, including a multidisciplinary team consisting of otolaryngologists, audiologists, psychologists, teachers, and social workers. These children underwent ear, nose, and throat (ENT) examination and audiological assessments, such as tynpanometry and assessment of acoustic reflexes, otoacoustic emissions (OAE), and auditory brainstem responses (ABR). RESULTS: Eight ears (26.7%) did not show ABR withcochlear microphonic (CM). Out of these 8 ears, 6 (75%) showed presence of OAE in isolated frequencies,whereas 2 (25%) did not show OAE at all tested frequencies. CONCLUSION: Based on the results of this study, 6 (40%) out of the 15 children tested showed characteristics related to ANSD.
