Middle ear effusion and newborn hearing screening

Area of Science:

• Pediatric Audiology
• Otolaryngology
• Neonatal Screening

Background:

• Middle ear effusion (MEE) is a common cause of failed newborn hearing screening.
• MEE can lead to conductive hearing loss, requiring extended follow-up.
• Understanding the long-term outcome of congenital MEE is crucial for effective management.

Purpose of the Study:

• To investigate the resolution rate and long-term fate of middle ear effusion in newborns who failed initial hearing screening.
• To assess the persistence of conductive hearing loss attributed to congenital MEE at a 1-year follow-up.

Main Methods:

• Retrospective analysis of medical records for newborns born between 2012-2013.
• Data extraction included Universal Newborn Hearing Screening (UNHS) results and follow-up audiological evaluations.
• Focus on infants diagnosed with conductive hearing loss due to MEE.

Main Results:

• 1.5% of 9527 newborns failed UNHS; 46 were diagnosed with MEE-related conductive hearing loss.
• Spontaneous MEE clearance occurred in 26% of cases.
• 57% had persistent effusion requiring further management, including ventilation tubes (22%) or continued monitoring (35%). 17% were lost to follow-up.

Conclusions:

• Congenital middle ear effusion causing UNHS failure and conductive hearing loss demonstrates significant persistence.
• Resolution rates for congenital MEE are lower compared to non-congenital MEE.
• Prolonged follow-up is essential for infants with congenital MEE.
