Various etiologies are attributed to the development of subjective tinnitus, but their inter-relationship with the presence of temporomandibular disorders and depression is still poorly understood. To assess the presence of depressive symptoms in individuals with TMD and subjective tinnitus, assessing the impact on their quality of life. This is a cross-sectional observational descriptive study. We evaluated 44 patients in a public University. For TMD diagnosis as well as assessment of depressive symptoms, the RDC/TMD questionnaire was used. Otolaryngological assessment was conducted by means of pure tone, speech, and immitance audiometry. The "Tinnitus Handicap Inventory" questionnaire was also administered. 84% of the individuals with tinnitus had myofascial pain, with the masseter muscle being the most prevalent area of pain, and 16% exclusively had painful and/or degenerative TMJ changes. Among the patients with myofascial pain, 86,5% had depressive symptoms, while among those without myofascial pain, only 42,8% presented these symptoms. Eleven (11) patients (25%) reported slight impact of tinnitus on quality of life, 15 (34%) mild impact, 7 (16%) moderate, 7 (16%) severe, and 4 (9%) catastrophic impact. There was a positive association between the presence of myofascial pain and depressive symptoms (p=0,02), as the intensity of tinnitus increases and the severity of depressive symptoms (p<0,01).
