PurposeThe incidence of sensorineural hearing loss (SNHL;>20 dB loss) in CDH survivors is debated. We evaluated long-term audiological outcomes at a single tertiary care center with ECMO capability and an established neonatal follow-up program.MethodsWith REB approval, records of CDH survivors from 2000 to 2010 were retrospectively analyzed. Demographic, postnatal, and audiometric information was gathered. All underwent auditory brainstem response (ABR) or otoacoustic emissions screening before discharge and complete audiological surveillance. Thirty-three patients were evaluated to age 4+ years with others continuing follow-up.ResultsForty-three patient records were reviewed with 1 excluded (transferred to another institution). Median GA and BW were 39 weeks (35-41) and 3.1 kg (2-4), respectively. Median ventilation days were 10 (2-189) with 34 infants ventilated 5+ days. Sixteen (36%) received HFOV, 21 (49%) iNO, and 5 (12%) ECMO. The median time to CDH repair was 3 days (1-23), and 11 (26%) required patch repair. Nine infants (21%) received diuretics and oxygen after discharge. Audiological surveillance identified only one patient with SNHL (received HFO, iNO, and patch repair).ConclusionNeonatal screening identifies CDH survivors at risk for hearing difficulties but must be followed with comprehensive testing until school age. The incidence of SNHL may be less than previously reported in this population.Copyright © 2013 Elsevier Inc. All rights reserved.
