Otoneurological assessment and quality of life of individuals with complaints of dizziness and temporomandibular disorders: a case-control study
Abstract Objectives: To evaluate the impact of temporomandibular disorders on the quality of life of patients with dizziness. Methods: An observational, case-control study evaluated 60 individuals with dizziness (20 cases and 40 controls), who were matched for gender and age. The individuals underwent to anamnesis, overall physical and otoneurological examination, tonal and vocal audiometry and impedanciometry, video head impulse test and the dizziness handicap inventory questionnaire. Results: The otoscopy was normal for all patients. There was an association between the presence of temporomandibular disorders and aural fullness (p<0.01) and otalgia (p<0.01). Audiometry was normal in 90% of the patients in the case group, with a significant association between temporomandibular disorders and normal audiometry (p<0.01). The video head impulse test findings were normal in 66% of the patients in the case group and 45% of the control group, and there was no association between having temporomandibular disorders and vestibular alterations at the video head impulse test (p = 0.12). There were significant differences in total dizziness handicap inventory and in the functional and emotional domains (p<0.01), with higher scores in the control group. Conclusion: Aural fullness and otalgia symptoms are associated with temporomandibular disorders in patients with dizziness, and there is an association between normal complementary audiological tests and temporomandibular disorders. Vestibular alterations are not associated with temporomandibular disorders. However, patients with dizziness and without temporomandibular disorders showed greater quality of life impairment. Level of evidence: 3. Original case-control study.
