| Abstract | |
The aim of this study was to determinate the prevalence of signs and symptoms of TMD and otologic symptoms in tinnitus patients. The association between the severity of TMD and tinnitus and the influence of tinnitus in patient´s quality of life and the level of depression were also addressed. Audiologic evaluation in tinnitus patients was performed in order to verify the association of hearing loss and TMD. Two hundred patients participated on this study, divided into two groups by an experimented Otolaryngologist. The experimental group was comprised of 100 tinnitus patients and control group was comprised of 100 individuals without tinnitus. All subjects were evaluated using RDC/TMD in order to determinate the presence of TMD. The severity of the TMD was determinated by using a self-reported anamnestic questionnaire. The influence of tinnitus in quality of life was determinated by the Tinnitus Handicap Inventory (THI). Depression level was determinate by the SCL-90 from RDC/TMD axis II. Audiologic evaluation was performed in 48 tinnitus patients with and without TMD. Chi-square, Mann-Whitney and Spearman tests were used in statistical analysis, with a 5% significance level. The prevalence of signs and symptoms of TMD in tinnitus patients was 85% and statistical association was found (p0.001). Stuffy sensations were found in 61% of patients (p0.001), dizziness in 52% of patients (p0.001), otalgia in 27% of patients (p0.001), hypoacusis and hyperacusis in 62% and 27% of patients (p0.001), respectively. The severity of TMD was positively associated with tinnitus (p0.001). The mean THI value for TMD was 33.38 while for non-TMD patients was 34.93, with no statistical difference (p=0.67) between them. Depression levels for tinnitus patients were statistically higher than non-tinnitus patients (p0.001). The prevalence of hearing loss in tinnitus patients was 4.17% and among TMD patients was 2.63%. It was concluded that tinnitus is associated with TMD, as well as with higher depression levels. On the other hand, hearing loss was not associated with TMD. (AU) | |
