Sensorineural Hearing Loss in Selective Immunglobulin A Deficiency.

Objective: To assess hearing functions in pediatric patients with selective immunoglobulin A (IgA) deficiency (SIGAD).

Methods: Pure-tone audiometry, acoustic impedance, otoacoustic emission, and brainstem audiometric measurements were taken during a non-infectious period in 28 patients with SIGAD and 28 healthy children with normal otoscopic examination. The results of the hearing tests were compared between the two groups.
