The frequent coexistence of tinnitus and temporomandibular joint and masticatory muscles disorder (TMD) has led to the assumption that there is a relationship between both conditions. The aim of this study was to evaluate the tinnitus prevalence in patients with TMD and the effects of its treatment on tinnitus. A total of 57 patients followed in a Stomatology - TMD consultation in 2021 and the first half of 2022 were included. The presence of tinnitus was questioned and the Tinnitus Handicap Index (THI) questionnaire was applied. 72% had 1 or more episodes of tinnitus. 89.5% were female and there were 2 peaks of incidence in the age group between 18-30 (21.1%) and 41-50 years (24.6%). In 85.4% of patients, tinnitus was intermittent and 41.5% had a reduced degree. An association was found between the side of tinnitus and TMD (p<0.001). 67% improved tinnitus after TMD therapy (p= 0.0135).
