Comprehensive otologic and audiological evaluations are very much essential for etiological assessment of hearing impaired children and management efficacy. Methods: A cross-sectional study was carried out with the aim to evaluate the etiological factors, degree of hearing loss, type of hearing loss, and results of aided audiogram among the below 12 years deaf children. The study included 100 deaf children below 12 years with history of deafness and non-development of speech. Result: The etiology of deaf Children was diverse. Infection was the predominating etiological factor (38%). The infections were: measles (31.5%), pneumonia (26.2%), typhoid (21.5%), maternal rubella (5.2%), varicella (5.2%), mumps (5.2%) and meningitis (5.2%). 48% of deaf child had a parental suspicion of deafness below the one year of age. 35% had a positive family history and 32% had history of consanguinal marriage. The deaf children were managed with hearing device, among them 89% with hearing aid and 11% with cochlear implant 42.7% of child used hearing aid in both ears. The results of aided audiogram reflected that, the gain after using hearing aid within 31-60 dB were 80%. 10% in right ear, 71.10% in left year and 70.00% in both ears, so average gain after using hearing aid was 74% within 31- 60 dB.
