Abstract
BACKGROUND
Hearing is a special sense needed for proper speech, language, mental development and academic performance. The objectives of our study were to screen neonates at rural area with otoacoustic emission device for detecting hearing impairment and develop a comprehensive rehabilitation model for hearing impaired children in rural areas. Hearing loss initial signs are subtle and therefore for early detection routine neonatal hearing screening is the most effective tool. At first otoacoustic emissions are done, failing which neonates undergo BERA as final screening method to identify hearing impairment as a confirmatory test. In a country like India where neonatal hearing tests are not a part of the routine screening program, the chances of missing early detection and possible rehabilitation are large. In this context, the current project envisages to develop a practical and pragmatic screening model for detecting early neonatal hearing impairment using otoacoustic emission technique in a rural sector reaching every door step possible.
METHODS
From the government health records collected for a duration of one and half years, all babies delivered in PHC were included for the screening. The babies were screened every Thursday (Immunisation day) with OAE devices by an audiologist at the PHC. The total number of infants screened were 1737. The first screening test done was otoacoustic emission, failing which patient was referred for BERA as a confirmatory test.
RESULTS
The total number of babies screened by OAE in our study was 1737. Out of the total infants screened, 1st OAE referrals were 327 babies. All the 327 infants were screened by OAE for the 2nd time, out of which 10 infants were referred for the 2nd consecutive time. 317 infants were passed on 2nd OAE screening. All the 10 infants who were referred for the 2nd time were subjected to BERA at Ramaiah medical Hospital. Out of these 10 infants, BERA showed severe to profound bilateral hearing loss in 7 infants (Confirmed Hearing loss). Other 3 infants had normal BERA reading hence normal hearing. The statistics showed that the overall rate of hearing loss prevalence was 4.03 per thousand.
CONCLUSIONS
In order to diagnose hearing loss in neonates, it is critical to identify hearing loss at birth and provide a screening test for it. OAE screening of neonates should be done at the earliest to detect hearing impairment so that hearing and speech rehabilitation can be started at the earliest. It should be done at each & every health care centre on a large-scale basis to cover all the babies.
