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.<\/jats:p><jats:p>The prevalence of new tinnitus ranged from 0.2 to 96.2%, whereas the prevalence of preexisting tinnitus varied from 8 to 76.2%.
