Insights
Early detection of hearing loss in high-risk infants is crucial. This study found 5% of infants had delayed sound localization, highlighting the need for pediatric hearing and speech follow-up.
Area of Science:
- Pediatrics
- Audiology
- Developmental Neuroscience
Background:
- Infants at high risk for deafness require early auditory and neurodevelopmental monitoring.
- Assessing auditory development, specifically sound localization, is key in early intervention.
Purpose of the Study:
- To detect moderate to profound hearing loss in high-risk infants.
- To track auditory and neuropsychomotor development during the first two years of life.
- To compare infant auditory responses with existing American literature.
Main Methods:
- Utilized the Hear Kit (Downs, 1984) for sound source localization assessment.
- Monitored neuropsychomotor development in infants up to two years of age.
- All infants underwent cerebral ultrasound assessment.
Main Results:
- One infant was identified with suspected hearing loss.
- Nine infants exhibited delays in neuropsychomotor development.
- Transversal analysis revealed distinct auditory response patterns compared to American literature.
Conclusions:
- A significant 5% of infants demonstrated delayed sound localization abilities.
- Emphasizes the importance and recommendation of medical speech and hearing follow-up for high-risk infants.
- Early intervention is vital for optimal outcomes in high-risk infants.

PURPOSES AND METHODS: The aims of this study were: to detect moderate to profound hearing loss in high risk infants for deafness, to follow up their auditory development (localization of the sound source- Hear Kit - Downs, 1984); and their neuropsychomotor development during the two first years of life. All subjects were submitted to cerebral ultra sound assessment.
Results:
An infant with a suspected hearing loss was identified and nine infants presented neuropsychomotor development delay. In a transversal analysis of the hearing assessment data it was verified that infants in this study presented different response than the referred in the American literature.
Conclusions:
It was concluded that 5% of the infants were delayed in localizing the sound source. Medical peech and hearing follow up during the two first years of life of high risk infants for deafness is important and advisable.
