Brain stem electric response audiometry and middle ear effusion.

Area of Science:

• Pediatric Audiology
• Otolaryngology
• Neuroscience

Background:

• Difficult-to-test children often present diagnostic challenges for hearing assessment.
• Middle ear effusion (MEE) is a common condition affecting hearing in children.
• Sensorineural hearing loss (SNHL) can be exacerbated by coexisting middle ear pathologies.

Purpose of the Study:

• To evaluate the prevalence of middle ear effusion in difficult-to-test children using brain stem electric response audiometry (BSER).
• To assess the impact of middle ear effusion on hearing aid amplification needs in this population.
• To emphasize the significance of early identification and management of middle ear pathology in children with SNHL.

Main Methods:

• Brain stem electric response audiometry (BSER) was conducted on 41 children under 8 years old.
• Pneumatic otomicroscopy was performed on all ears before BSER threshold determination.
• Prevalence of MEE and its association with hearing aid use were analyzed.

Main Results:

• Middle ear effusion was detected in 24 (29.3%) of the examined ears.
• Among children requiring hearing aids, 7 out of 14 (42.9%) had fluid in their ears.
• A significant proportion of difficult-to-test children had concurrent middle ear pathology.

Conclusions:

• Middle ear effusion is highly prevalent in difficult-to-test children and can impact audiological assessments.
• Early recognition and treatment of middle ear pathology are essential for effective management of SNHL in children.
• Routine otomicroscopy by otologists is recommended for comprehensive pediatric hearing evaluations.
