INTRODUCTION: COVID-19 may have many nonspecific symptoms, such as hearing loss, tinnitus and dizziness. This study aims to investigate the effects of SARS-CoV-2 on the hearing thresholds of patients with COVID-19.
METHODS: A total of 20 patients aged 20-55 years who were diagnosed with COVID-19 were included in this study. The relationship between the pure-tone thresholds of patients before and after COVID-19 was evaluated.
RESULTS: There was no statistically significant difference between bone conduction pure-tone thresholds in all frequencies before and after COVID-19.
CONCLUSION: SARS-CoV-2 has no effects on the hearing thresholds in patients with non-hospitalized mild COVID-19 disease. Further studies are needed to investigate the possible effects of SARS-CoV-2 on the auditory system.
