Universal Neonatal Hearing Screening - a Necessity and not a Choice
Journal Title: Bengal Journal of Otolaryngology and Head Neck Surgery - Year 2015, Vol 23, Issue 1
Abstract
INTRODUCTIONCongenital deafness in a child is often missed. Several distraction tests have evolved over time to diagnose congenital deafness. These are of limited value in the era of Evoked response audiometry. Evoked responses, such as Oto-acoustic emission (OAE) and Brainstem Evoked Response Audiometry (BERA) have played a significant role in early diagnosis of congenital hearing impairment. The study was conducted to compare the result of neonatal hearing screening in high risk and non high risk neonates.MATERIALS AND METHODSA study was conducted over a time period of three months at a tertiary care institute to screen all live neonates for congenital hearing impairment using OAE and BERA.RESULT1182 neonates were screened for hearing impairment. 336 were in High risk group and rest in Non high risk group. Nine neonates turned out to have abnormal BERA result (absence of wave V). Six of them were high risk babies and rest 3 were non high risk.DISCUSSION33.33% of congenital deaf population detected by UNHS belong to the Non High Risk group. Studies across the world suggest at least 50% chance of missing out a congenital deaf child if Universal Neonatal Hearing Screening is not practiced. CONCLUSIONIn order to ensure that early detection and effective intervention are made on all newborns with hearing impairment, UNHS should be performed. Three stage UNHS protocol using TEOAEs and BERA showed that the implementation of UNHS for congenital childhood hearing loss among all newborns in India feasible and effective.
