Aim: Crimean-Congo Hemorrhagic Fever (CCHF) is a tick-borne viral disease, and Sensorineural Hearing Loss (SNHL) arises from pathologies in the cochlea or retrocochlear pathways. Viral infections, including Crimean-Congo hemorrhagic fever are considered possible etiological factors for Sensorineural hearing loss, as endothelial damage in Crimean-Congo hemorrhagic fever may impair inner ear blood flow. This study aimed to differentiate between cochlear and retrocochlear hearing loss in patients with CrimeanCongo hemorrhagic fever and assess the reliability of Auditory Steady-State Response (ASSR) testing by comparing its results with pure-tone audiometry. Materials and Methods: The study included 30 Crimean-Congo hemorrhagic fever patients (Group CCHF) and 30 healthy controls (Group C). Hearing measurements were conducted using pure tone audiometry, otoacoustic emissions, tympanometry, and Auditory steady-state response before the patients’ discharge. Data were analyzed using SPSS 22.0. Results: The results showed no significant difference in audiometric thresholds between the right and left ears of Group CCHF at various frequencies. However, Auditory steadystate response results at 1000, 2000, and 4000 Hz in the right ear and at all tested frequencies in the left ear revealed significant differences between groups (p<0.05). Conclusion: While this study did not establish a clear link between Crimean-Congo hemorrhagic fever and Sensorineural hearing loss, it suggests the need for further research with larger samples and testing during both the active and recovery phases of CrimeanCongo hemorrhagic fever.
