Objective: To report results of audiometric evaluations in high-risk congenital diaphragmatic hernia survivors and their exposure to audiological risk factors (mechanical ventilation, high frequency oscillation, aminoglycoside therapy and neuromuscular blocking agents). Design: All newborns with high-risk congenital diaphragmatic hernia born between January 2003 and June 2009 were treated consecutively at the Neonatal Intensive Care Unit, Pediatric Hospital, University of Padova. Thirty-two survived and 26 of them underwent formal audiological evaluation (tonal and speech audiometry, otoacoustic emission, and immitance measurements) and follow up. Results: Twenty-one children had normal hearing; 4 had conductive hearing loss, which was successfully treated; and 1 had severe sensorineural hearing loss and suffers from Turner syndrome. Conclusions: Our series revealed a lower prevalence of sensorineural hearing loss in high-risk congenital diaphragmatic hernia survivors than in other studies, suggesting that the association between hearing loss and congenital diaphragmatic hernia has yet to be accurately defined and fully elucidated.
