Abstract


Background: Childhood hearing impairment is a significant public health condition associated with long-term academic and communicative difficulties. Causes can be congenital or acquired. Nearly half of the known causes can be prevented by primary public health methods.

Methods: 1003 children, aged 6 to 17 years, from the schools in the Doiwala block district Dehradun were randomly selected and examined. Clinical otologic assessment and Pure tone audiometry screening were conducted on all participants.  

Results: The prevalence of hearing impairment was 19.6%. The hearing impairment in majority of cases was of a mild degree i.e., 26 to 40 dB (93.9%) of which majority of children (99.0%) had conductive loss. Wax was the commonest cause of hearing loss (79.2%). CSOM was found in 19.0% children.

Conclusions: The prevalence of hearing impairment in school going children in rural area district Dehradun was high.
