An Epidemiological Study of Hearing Loss in a Peripheral Tertiary Care Hospital.

Abstract

The estimated prevalence of adult onset hearing deafness in India is 7.6% and childhood onset hearing loss is 2%. But there are very few studies which highlight the prevalence of various types of hearing loss. So a retrospective, cross-sectional study in a peripheral tertiary care hospital was designed to analyze the different types of hearing loss among patients with complaints of hearing disabilities attending and assess the more prevalent type of hearing loss according to severity. Out of total study population of 14,365 patients, Male patients with Mild hearing loss have the maximum correlation coefficient followed by Moderate, Moderately severe, Profound and Severe hearing loss. In the case of female patients Mild Hearing loss has the maximum correlation coefficient. Result of this study may be helpful in planning and management of different programs related to hearing disability prevention. As most of the hearing loss is mild variety and it slowly progress to other form of severe hearing loss, early intervention is very helpful in reducing the severity thus disability.
