Summary
Distortion product otoacoustic emission (DPOAE) offers a practical hearing screening for NICU infants. This quick test shows high accuracy, making it a potential primary hearing assessment tool.
Area of Science:
- Neonatal audiology
- Otoacoustic emissions
- Auditory evoked potentials
Context:
- Neonatal intensive care units (NICUs) require efficient hearing screening for high-risk infants.
- Traditional auditory brain stem response (ABR) testing is time-consuming.
- Distortion product otoacoustic emission (DPOAE) offers a non-invasive alternative.
Purpose:
- To evaluate the efficacy of DPOAE as a hearing impairment screening tool in neonates under intensive care.
- To compare the performance of DPOAE with auditory brain stem response (ABR).
Summary:
- 64 neonates underwent both DPOAE and ABR testing.
- DPOAE demonstrated high practicality and speed.
- Recordable DPOAEs were obtained in 83.6% of NICU infants.
- DPOAE sensitivity and specificity were 92.4% and 92.2% respectively, compared to ABR.
- False positive rate was 7.8%, and false negative rate was 7.6%.
Impact:
- DPOAE's speed and accuracy suggest its utility as a primary hearing screening method for neonates.
- Further research with larger cohorts is needed to confirm DPOAE's sensitivity for long-term hearing impairment.
