Objective: Celiac disease ( CD) is a gluten-triggered immune enteropathy caused by a genetic predisposition. Recent papers suggest that CD is increasingly recognized by extraintestinal findings. The aim of this study was to investigate the effect of CD on hearing pathway including the olivocochlear efferent system in children. Methods: Forty-one pediatric CD patients and 31 controls were included in the study. Both groups were evaluated with audiometry, tympanometry, transiently evoked otoacoustic emission (TEOAE), distortion product otoacoustic emission (DPOAE), and contralateral suppression of the TEOAE. Results: The threshold at 250 Hz of the patients with CD was significantly higher (p < 0.05 in CD compared to control group, p < 0.0001). The signal to noise ratio (SNR) amplitudes in DPOAE testing and the SNR amplitudes with and without contralateral acoustic stimulus in TEOAE testing were significantly lower at 1,000 Hz in the CD compared to the control group. There was no significant difference between the CD and the control group regarding contralateral suppression amplitudes. Conclusion: CD seems to have an important impact on the auditory system, and results in an elevation of the thresholds at 250 Hz on audiometry and a decrease in the amplitudes of DPOAE and linear TEOAE at 1,000 Hz in children.
