Sachin Jain

Background: Auditory neuropathy/dys-synchrony (AN/AD) is a hearing disorder characterized by an absent or atypical auditory brainstem response. The present study was conducted to evaluate cases of Auditory neuropathy/dys-synchrony with hearing loss. Materials & Methods: The present study was conducted on 218 patients diagnosed with hearing loss age ranged 1- 14 years of both genders. All patients were subjected to hearing screening tests (tympanometry, TEOAE, DPOAE, AABR). The prevalence of AN/AD was assessed. Results: Out of 218 patients, 8 (3.67%) had AN/ AD. Acoustic reflex was present in 8, high Bilirubin was present in 7, blood exchange after birth was seen in 6 and neonatal intensive care was required in 6. The difference was significant (P<0.05). Conclusion: Authors found that cochlear-sensitive auditory test (OAE) and the auditory brain stem response (ABR) is necessary for the early diagnosis of AN/AD. Key words: Auditory neuropathy, cochlear-sensitive auditory test, hearing
