Summary
A two-stage hearing screening model using otoacoustic emissions (OAE) and auditory brainstem response (ABR) effectively identifies newborn hearing loss. This method helps determine the prevalence of congenital hearing impairment in infants.
Area of Science:
- Neonatal audiology
- Hearing screening technologies
- Congenital hearing loss
Context:
- Newborn hearing screening is crucial for early detection of hearing loss.
- Existing screening methods require validation for optimal efficacy.
- Understanding the prevalence of hearing impairment is essential for public health initiatives.
Purpose:
- To evaluate a two-stage hearing screening model for newborns.
- To determine the prevalence of congenital hearing loss in the studied population.
- To assess the combined efficacy of otoacoustic emissions (OAE) and auditory brainstem response (ABR) tests.
Summary:
- A two-stage screening process involving otoacoustic emissions (OAE) and auditory brainstem response (ABR) was implemented for 3,075 newborns.
- The initial OAE screening passed 90.4% of infants; a second OAE test and ABR were used for those who failed.
- Six out of 25 infants who failed the ABR test were diagnosed with hearing impairment, indicating a prevalence consistent with literature.
Impact:
- The proposed OAE and ABR combined screening model is effective for identifying newborns with hearing loss.
- This study contributes to establishing optimal protocols for universal newborn hearing screening.
- Findings support the implementation of robust screening programs to mitigate the effects of congenital hearing loss.
