Comparison of One-Year auditory rehabilitation outcomes by etiology in pediatric patients with bilateral severe hearing loss (70-90 dB): enlarged vestibular aqueduct vs. Other causes.

ABSTRACT:

Purpose

This study aimed to compare short-term language outcomes following hearing aid rehabilitation in pediatric patients with severe bilateral hearing loss (70-90 dB), with a particular focus on differences according to etiology. We hypothesized that children with enlarged vestibular aqueduct (EVA) exhibit more favorable speech development compared to those with other genetic or structural causes of hearing loss, and explored the potential presence of a "hidden" air-bone gap associated with EVA.

Methods

We retrospectively reviewed 36 children under five years of age diagnosed with bilateral severe sensorineural hearing loss and ascertained before age two at Seoul National University Bundang Hospital. Patients were classified into EVA (n = 16) and non-EVA (n = 20) groups b
