Abstract
Background: The aim of the study was to do universal hearing screening of all newborns using otoacoustic emission (OAE), to know the incidence and risk factors of hearing loss in neonates.Methods: This was a prospective observational study done in a tertiary care hospital in Mangalore city in Karnataka. 950 neonates were screened with distortion product otoacoustic emission (DPOAE) during the study period of one year from 2017 to 2018. A repeat test was done at one and a half months of age if the first test failed. Auditory brain stem evoked response (ABER) was performed at 3 months of age if both the tests failed. Babies with hearing loss were referred to ENT specialist for further management. Comparison of the variables was done by student's t test and Chi-square test. P-value <0.05 was considered statistically significant.Results: Out of the 950 newborns screened with DPOAE test, 204 (21.4 %) babies had abnormal screen either in single or both ears. 7 out of 204 (3.43%) babies had abnormal OAE on repeat testing at one and half months. 2 out of 7 babies (0.96 %) had significant hearing loss ABER was performed at 3 months of age.Conclusions: Early identification by screening of hearing loss prevents a significant public health concern. Early recognition and intervention prior to 6 months have a significant positive impact on development.
