Abstract

Purpose: Tinnitus and temporomandibular disorders have already been associated in the literature, but despite many studies, it is still an intriguing discussion point. This study aimed to evaluate the prevalence of hearing loss among somatosensory tinnitus patients with temporomandibular disorders and to assess the influence of tinnitus on patients' quality of life. Method: An otolaryngologist examined 585 patients in order to detect and evaluate the presence of tinnitus. Subjects were evaluated using the Portuguese version of the Research Diagnostic Criteria for Temporomandibular Disorders. An analysis of the somatic component of tinnitus was performed. Tinnitus was rated according to its onset (at least 6 months) and intensity with a visual analog scale. The sample was composed of 100 patients with somatosensory tinnitus divided into two groups: Group 1 (with temporomandibular disorder, n = 85) and Group 2 (without temporomandibular disorder, n = 15). The audiological evaluation was composed of puretone audiometry, high-frequency audiometry, tympanometry, and transient-evoked otoacoustic emissions. The impact of tinnitus on quality of life was assessed by the Tinnitus Handicap Inventory adapted and validated to Portuguese language. Results: Pure-tone audiometry did not differ with statistical significance between groups (p = .29), neither did the highfrequency audiometry results (p = .74). Tinnitus Handicap Inventory scores also did not show any differences between Groups 1 and 2 (p = .67). Conclusions: Subjects with somatosensory tinnitus, who also have temporomandibular disorders, do not seem to have hearing impairment. Also, they do not have a higher quality of life handicap when compared to those without tinnitus and temporomandibular disorder. (AU)
