Outcome of newborn hearing screening a prospective study
Keywords:Otoacoustic emissions, Hearing loss, Screening of newborn for hearing
Background: Hearing is a very important part of newborn language as well as speech development, hearing loss varies degrees i.e. from hearing impairment to complete hearing loss. It has an effect on person’s physical, social, mental, educational, and economic well-being.
Methods: The current study's objective was to use OAE to test newborns for hearing in the department of otorhinolaryngology and study was carried out over a period of 2 years (September 2020 to September 2022) in 2000 neonates born at Rajindra hospital Patiala by DPOAE (distortion product OAE) test. The association between maternal, neonatal, sociodemographic factors and hearing impairment in neonates were evaluated.
Results: In our study 257 out of 2000 newborns had ‘Refer’ result on OAE. There was a male preponderance (1061 males and 939 females) with 7% males having ‘Refer’ results as compared to 5.85% of females.153 out of 2000 neonates with ‘Refer’ result belonged to the lower class and 9.9% newborns with ‘Refer’ result was from rural area. Perinatal illnesses like Severe anemia (1.17%), Hypertension (0.78%) also have an impact on neonatal hearing impairment. In neonatal risk factors prematurity caused hearing impairment in 7.85% of neonates, low Apgar score at birth and 1 min (8.55% and 8.35%), low birth weight (8.75%), and more than 24-hour NICU admission (3.7%)
Conclusions: The screening of neonates with Otoacoustic emissions is required for early detection of neonatal hearing loss as OAE is an easy,reasonably priced and dependable procedure for infant testing on a wide scale.
