Summary
Transient evoked otoacoustic emissions (TEOAE) and distortion product otoacoustic emissions (DPOAE) show promise for newborn hearing screening. Specific criteria, r ≥ 0.60 for TEOAE and P5 for DPOAE, offer effective pass/fail guidelines.
Area of Science:
- Audiology
- Neonatal Care
- Diagnostic Tools
Background:
- Newborn hearing screening is crucial for early identification of hearing loss.
- Otoacoustic emissions (OAE) offer an objective measure of cochlear function.
- Establishing reliable OAE screening criteria is essential for widespread adoption.
Purpose of the Study:
- To validate transient evoked otoacoustic emissions (TEOAE) and distortion product otoacoustic emissions (DPOAE) for newborn hearing screening.
- To determine effective pass/fail criteria for OAE screening in neonates.
Main Methods:
- 108 newborns (216 ears) underwent screening using TEOAE and DPOAE.
- OAE results were compared against auditory brainstem response (ABR) test outcomes.
- Celesta 503 Cochlear Emission Analyzer was used for OAE measurements.
Main Results:
- TEOAE screening with r ≥ 0.60 achieved 100% co-positivity and 93.8% co-negativity with ABR.
- DPOAE screening using P5 criteria yielded 100% co-positivity and 94.3% co-negativity with ABR.
- The combination of TEOAE (r ≥ 0.60) and DPOAE (P5) demonstrated strong correlation (r = 0.6583).
Conclusions:
- r ≥ 0.60 and P5 are feasible pass criteria for TEOAE and DPOAE, respectively, in newborn hearing screening.
- Otoacoustic emissions (OAE) serve as an objective, rapid, and effective tool for universal newborn hearing screening.
