Prevalência de zumbido e efeito do tratamento em pacientes com distúrbio da articulação temporomandibular

Abstract

Introduction: Temporomandibular Disorders (TMD), also known as craniomandibular disorders are diseases that affect the temporomandibular joint (TMJ). The relationship between TMD and the origin of tinnitus in these patients is not yet clearly defined. Many hypotheses have emerged to explain the correlation between auditory symptoms and temporomandibular changes. Aims: To evaluate the prevalence of tinnitus and analyze the influence of the proper treatment of TMD in tinnitus in selected patients. Methods: The material of this study consisted of patients diagnosed with TMD accompanied by an expert in the area between the years 2011 to 2013 (2 years). Patients were analyzed in relation to age, gender, presence or absence of tinnitus, as well as intensity and characterization of the same, besides improves or not after treatment. Results: The prevalence of tinnitus in the sample studied was 34.6%. Among patients who reported tinnitus, 15 were women and three were men and the age range was 18-71 years with an average of 47.3 years. After treatment, we noted a significant improvement of tinnitus in most patients, and 4 of them were in complete remission of tinnitus. Discussion: The results of this study show a prevalence of tinnitus lower than that found in the literature and demonstrate the improvement of tinnitus with proper treatment, as reported in other studies. Conclusion: We found a prevalence rate of 34.6% of tinnitus in patients with TMD. It was observed that these patients showed improvement of such symptoms, either partial or complete after treatment.
