UEMOTO, Luciana et al. Impact of supportive therapy for otological changes in patients with temporomandibular joint disorders. Rev. dor [online]. 2012, vol.13, n.3, pp.208-212. ISSN 1806-0013.

BACKGROUND AND OBJECTIVES: Otological symptoms complaints may be associated to temporomandibular joint disorders (TMJD). Occlusal splint is an alternative to treat TMJD because it provides ideal occlusion to patients, acting on painful symptoms. Considering the conservative and reversible characteristics of supportive therapy with occlusal splints, this study aimed at evaluating its impact on the frequency of otological changes in TMJD patients. METHOD: An intervention study was carried out with 35 patients with TMJD-associated otological symptoms. TMJD patients were considered those with at least three signs and three symptoms of morbidity, being one of them earache, tinnitus, sensation of hypoacusis, ear fullness or dizziness. Patients were submitted to clinical evaluation, orientations and fabrication of maxillary occlusal splint in thermoplastic acrylic resin. Splint adjustments and symptoms evaluation were performed fortnightly. Fisher Exact test was used for statistical analysis of the prevalence of signs and symptoms before (BE) and after (AF) therapy with significance level of 5% (p < 0.05). RESULTS: Nineteen patients have finished the treatment. There has been decrease in the prevalence of otological signs and symptoms: tinnitus (BE = 14; AF = 6; p = 0.009), earache (BE = 13; AF = 4; p = 0.003), ear fullness (BE =12; AF = 4; p = 0.006), dizziness (BE = 11; AF = 4; p = 0.009) and hypoacusis (BE = 10; AF = 2; p = 0.001). CONCLUSION: Occlusal splint is a conservative and reversible therapy able to improve TMJD-related otological symptoms.
