Insights
Early hearing screening in high-risk newborns identified a significant prevalence of hearing impairment. 15% of infants showed hearing loss, emphasizing the critical need for prompt audiological testing in infants.
Area of Science:
- Pediatrics
- Audiology
- Neonatal Care
Background:
- Hearing impairment affects a substantial portion of the population.
- Early intervention is crucial for proper infant development.
- High-risk newborns require targeted audiological surveillance.
Purpose of the Study:
- To determine the prevalence of hearing impairment in high-risk infants.
- To assess the effectiveness of early audiological testing protocols.
Main Methods:
- Evaluated 100 newborns using evoked otoacoustic emissions (OAE) and auditory behavior (BOA).
- Referred infants with altered results for impedance testing and medical evaluation.
- Utilized Brainstem Auditory Evoked Potential (BAEP) testing for referred infants.
Main Results:
- 85% of infants had hearing within normal limits.
- 15% of infants were diagnosed with hearing impairment.
- Of those with impairment, 7 had unilateral and 8 had bilateral hearing loss.
Conclusions:
- A high prevalence of hearing impairment was observed in this high-risk infant cohort.
- Early audiological testing is essential for timely diagnosis and intervention.
- Systematic screening programs are vital for identifying hearing loss in newborns.
Abstract:
Hearing impairment is prevalent in the general population, early intervention facilitates proper development. The aim of this study was to establish the prevalence of hearing impairment in high-risk infants born between 2013 and 2014. 100 newborns were evaluated using evoked otoacoustic emissions and distortion produce and auditory behavior. Tests were reported if the results were altered. If altered results persisted, the child was referred for impedance testing and when necessary for medical evaluation. Infants referred for BOA and OAE undergone Brainstem auditory evoked potential testing. Of 100 children, 85 children have hearing within normal limits. Hearing impairment was found in 15 out of which 7 had unilateral hearing loss and 8 had bilateral hearing loss. The high prevalence of hearing impairment in this population underlines the importance of early audiological testing.
