Abstract	ObjectiveCOVID-19 is an infectious disease caused by the new coronavirus that starts similar to an upper respiratory tract infection and causes death by causing pneumonia and vasculopathy. Many viral infections are known to cause hearing loss. In this study, pure-tone audiometry (PTA) thresholds and Transient Evoked Otoacoustic Emissions (TEOAE) results were compared across patients with COVID-19 disease and COVID-19 pneumonia, and control group patients.MethodsThe study included 240 patients in the age range of 18–50 years. The patients were divided into three groups of 80 patients as the control (no disease), COVID-19 (nonpneumonia), Covid-19 (pneumonia) groups. PTA and TEOAE tests were performed on the control group patients and the results were recorded. PTA and TEOAE tests were performed in the COVID-19 groups in the first and third months after the infection ended. Each test was performed twice; the results were recorded, and the mean of the two results was calculated.ResultsPTA results and TEOAE amplitudes in the first and third months were not significantly different between the COVID-19 non-pneumonia group and the control group (p > 0.05), between the COVID-19 pneumonia group and the control group (p > 0.05), and between the COVID-19 non-pneumonia group and the COVID-19 pneumonia group (p > 0.05).ConclusionsDespite minimal impairment and minimal amplitude decreases in patients, who recovered from COVID-19, such changes were found to become restored in the third month. Furthermore, no significant changes were observed to indicate COVID-19- associated hearing loss.
