Abstract:	Objective The aim of this study was to investigate cochlear involvement in child patients with Crimean-Congo hemorrhagic fever (CCHF) disease. Methods Twenty-eight CCHF disease patients (56 ears) and 26 sex- and age-matched healthy control subjects (52 ears) were included in the study. Pure-tone audiometry at frequencies 0.25, 0.5, 1, 2, 4, and 6 kHz, immittance measures including tympanometry and acoustic reflex testing, and transient evoked otoacoustic emission (TEOAE) testing were performed in the patients and controls. Results The proportion with a result of ‘fail’ for the TEOAE test in the CCHF patients was not statistically significant from the control group (p > 0.05). Conclusions CCHF disease does not impair cochlear function in children. The clinical course of CCHF among children seems to be milder than in adults.
