Hearing impairment and otitis media in a rural primary school in south India.
In order to determine the prevalence of hearing impairment and otitis media in rural primary school children, a pilot study of 284 children aged 6-10 years was performed. These children were screened by otoscopy, pure tone audiometry and tympanometry. The overall prevalence of otological abnormalities (excluding wax) was 21.5%. Hearing impairment was detected in 34 children (11.9%). Conductive hearing impairment was predominant (10.9%). Otitis media was diagnosed in 17.6% of children. While 91.2% of children with hearing impairment had associated middle ear disease, only 53.4% of those with middle ear disease were detected as have hearing impairment. The importance of including tympanometry as part of the screening protocol is highlighted.
