Introduction: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has brought up reports of an increase in new cases of tinnitus and changes in chronic and/or preexisting episodes. Nevertheless, there is no established data on the characteristics of tinnitus and its correlation with coronavirus disease 2019 (COVID-19).
Objective: To analyze the characteristics of tinnitus in subjects affected by COVID-19 while detailing the correlation between these two factors.
Data synthesis: We found 327 articles, 37 of which were selected: 11 cross-sectional studies, 4 case-control studies, 3 cohort studies, and 19 observational studies. The sum of the samples totaled 399,524 patients included in the present review. The prevalence of new tinnitus varied from 0.2% to 96.2%. Most articles provided incomplete information or were missing information. Systemic arterial hypertension was the most common underlying disease. Finally, we found a predominance of hearing loss and olfactory and taste disorders, followed by fever and cough.
Conclusion: The prevalence of new tinnitus ranged from 0.2 to 96.2%, whereas the prevalence of preexisting tinnitus varied from 8 to 76.2%. It was not possible to satisfactorily assess the characteristics of tinnitus. Therefore, a direct correlation between tinnitus and COVID-19 could not be determined, as this symptom may be influenced by other factors.
