Auditory neuropathy is a disorder characterized by sensorineural hearing loss and absence of auditory evoked brainstem with otoacústicas emissions present, finding a loss of hearing in the presence of cochlear function, being the anomaly suggestive of impaired neural synchrony. Auditory Neuropathy has low incidence in children with normal hearing functions and a variable incidence in children with severe hearing loss, the actual management of neuropathy is aimed at the rehabilitation hearing, using amplification systems (hearing aids or cochlear implants).We performed a cross-sectional study aimed to compare the response in children with auditory neuropathy and sensorineural hearing-impaired children in terms of functional gain amplification systems. Were taken 4 children with confirmed diagnosis of the disease and compared with a control group of 16 children with sensorineural hearing loss of other etiologies, we compared the value of functional gain with hearing aids and cochlear implants, which was obtained from audiometric test. The global functional gain with both types of amplification does not show significant differences compared the two groups, comparing the group of patients with auditory neuropathy were no significant differences between hearing aid and implant for mid and high frequencies. We can conclude that the hearing aid in patients with auditory neuropathy is the amplification system that offers better functional gain values, even better than cochlear implant.
