Summary: | Introduction: The Auditory Neuropathy is described recently as a hearing loss characterized by the preservation of outer hair cells and absence of auditory brainstem responses. Objective: To present a case report of hearing aid fitting in a patient with Auditory Neuropathy. Case Report: S.A.P., male, 32 years old, sought the Otorhinolaryngology Service after five years of Guillain-Barré syndrome, complaining of progressive and bilateral tinnitus auditory loss in both ears. The audiological evaluation resulted in: severe sensorioneural hearing deficiency with bilateral irregular configuration; speech recognition rate of 0% and speech detection rate in 35dB in both ears; type A tympanometric curve and absent ipsilateral, bilateral and contralateral reflexes; absence of waves and presence of cochlear microphonics in both ears in the auditory evoked potential and present bilateral distortion product-evoked otoacoustic emissions. The speech perception test was performed with polysyllabic words and lip reading, and presented 44% of hit with hearing aid and 12% without it. Final Comments: Despite the differences in the process of hearing aid habilitation and rehabilitation, we conclude that sound amplification brought benefits to the patient with auditory neuropathy. |
