Summary
Newborn hearing screening is crucial. A two-step approach using Transient Evoked Otoacoustic Emissions (TEOAE) and Brainstem Evoked Response Audiometry (BERA) is recommended for effective infant hearing assessment.
Area of Science:
- Neonatal care
- Audiology
- Public health
Background:
- Newborn screening examinations are essential.
- General hearing screening for newborns is not yet widely implemented globally.
Purpose of the Study:
- To evaluate the effectiveness of different hearing screening methods in newborns.
- To compare the costs of one-step versus two-step newborn hearing screening protocols.
Main Methods:
- 100 newborns (200 ears) were screened on their third day of life.
- Transient Evoked Otoacoustic Emissions (TEOAE) using ECHOSCREEN and ILO-88 were employed.
- Brainstem Evoked Response Audiometry (BERA) using ALGO PORTABLE or EVOFLASH was conducted on 100 ears as a comparative method.
Main Results:
- 4.5% of ears screened with ECHOSCREEN showed abnormalities due to earwax.
- No abnormalities were detected with the ALGO-system.
- The EVOFLASH system identified seven ears (4 children) with abnormalities.
- Cost analysis indicated that two-step screenings (TEOAE and BERA) are cost-effective.
Conclusions:
- A two-step screening approach combining TEOAE and BERA devices is recommended for newborn hearing assessment.
- This combined method offers a reliable and potentially cost-effective strategy for early detection of hearing impairment in infants.
