Abstract
OBJECTIVE: This study aimed to compare the peripheral-to-central auditory systems of people with coronavirus disease 2019 to a well-matched control group and examine the long-term effects of coronavirus disease 2019 on the auditory system. METHOD: Participants who were outpatients of coronavirus disease 2019 (n = 30) were compared with a well-matched control group (n = 30). Behavioural and electrophysiological tests were performed, and tests were repeated at six months in the coronavirus disease 2019 group. RESULTS: Statistically significant differences were observed in the right ear at 10 kHz (p = 0.007) and 12.5 kHz (p = 0.028), and in the left ear at 10 kHz (p = 0.040) and 12.5 kHz (p = 0.040) between groups. The groups had no difference regarding the other audiological test results (p > 0.05). CONCLUSION: Extended high-frequency thresholds were affected in the coronavirus disease 2019 patients. No other findings indicated that the peripheral-to-central auditory system was affected. The effect on extended high-frequency thresholds appeared permanent, but no clinically significant new, late-onset auditory system effects were observed.
