Results: Bilateral affectation was commoner among those that have hearing impairment n = 366(65.2%) 91.2% while n = 54(8.8%) was found to have normal hearing. Majority of the ears had profound degree of hearing loss n= 313 (25.4%) with the highest number of it found in the right ear 27.0% however, there is no statistical significance between the side of the ear affected and the degree of hearing loss.
