Using transient evoked otoacoustic emissions for neonatal hearing screening

Area of Science:

• Audiology and Hearing Science
• Neonatal Health and Screening
• Public Health Interventions

Background:

• Early identification of hearing loss in newborns is crucial for timely intervention and improved developmental outcomes.
• Existing screening methods may face challenges in terms of cost-effectiveness and widespread implementation.
• The need for a reliable and efficient screening tool for universal newborn hearing programs is well-established.

Purpose of the Study:

• To assess the feasibility of a valid and cost-effective method for newborn hearing screening.
• To evaluate the efficacy of universal early identification programs for hearing loss.
• To determine the potential of transient evoked otoacoustic emissions (TEOAEs) as a primary screening tool.

Main Methods:

• Implementation of a hospital-based early identification program utilizing transient evoked otoacoustic emissions (TEOAEs).
• Screening of a large cohort of newborn infants (1850 in the first sample, 1451 in the second).
• Analysis of hearing loss identification rates and trends within the screened populations.

Main Results:

• Sensorineural hearing loss was identified in 11 out of 1850 infants in the initial sample.
• A second sample of 1451 infants demonstrated comparable trends in hearing loss detection.
• TEOAE screening proved effective in identifying hearing impairments within the studied newborn populations.

Conclusions:

• Transient evoked otoacoustic emissions (TEOAEs) demonstrate significant potential as a reliable newborn hearing screening tool.
• A carefully designed, hospital-based early identification program using TEOAEs is feasible and effective.
• Universal screening programs utilizing TEOAEs can facilitate early detection and intervention for infant hearing loss.
