The prevalence of hearing loss in children with congenital diaphragmatic hernia: A longitudinal population-based study.

Background: The true prevalence of hearing loss among children with congenital diaphragmatic hernia (CDH) is unknown, with some studies reporting rates up to 60%.

Purpose: The purpose of this study was to determine the prevalence of hearing loss among children with CDH and compare it to age-matched controls.

Methods: We used population-based datasets to compare the number of hearing loss diagnoses in children younger than 10 years-of-age born between 1992 and 2009 with CDH to date-of-birth matched controls without CDH.
