[The application of otoacoustic emissions in paediatric hearing screening]
Insights
Otoacoustic emissions (OAE) offer a fast and reliable hearing screening for infants. This method proved highly sensitive and specific compared to auditory brainstem response (ABR), making it ideal for pediatric audiology.
Area of Science:
- Pediatric Audiology
- Neonatal Hearing Screening
Background:
- Infant hearing loss impacts development.
- Early detection is crucial for intervention.
- Screening methods require high accuracy and efficiency.
Purpose of the Study:
- To evaluate otoacoustic emissions (OAE) as a primary hearing screening tool for high-risk infants.
- To compare the efficacy of OAE with auditory brainstem response (ABR).
Main Methods:
- Auditory screening of 132 high-risk infants.
- Utilized both otoacoustic emissions (OAE) and auditory brainstem response (ABR).
- Calculated sensitivity, specificity, and test duration for OAE versus ABR.
Main Results:
- OAE passing rate: 88.3% (233/264 ears).
- ABR passing rate: 92% (243/264 ears).
- OAE sensitivity: 90.5%; Specificity: 95%.
- Mean test time: 3 min for OAE vs. 30 min for ABR.
Conclusions:
- Otoacoustic emissions (OAE) demonstrate high sensitivity and reliability for infant hearing screening.
- OAE is a significantly faster screening method than ABR.
- OAE is a recommended, convenient tool for pediatric hearing assessment.
Abstract:
We conducted auditory test of 132 high risk infants by using both otoacoustic emissions (OAE) and auditory brainstem response (ABR) screening. The result showed that the passing rate was 88.3% (233/264 ears) for OAE and 92% (243/264 ears) for ABR. The sensitivity and specificity of OAE in comparison to ABR were 90.5% (19/21 ears) and 95% (230/243 ears) respectively. The mean test time was 3 min for OAE and 30 min for ABR. We therefore conclude that OAE is a highly sensitive, reliable and convenient method to be used for paediatric hearing screening.
