•SVV test evaluates the static otolith system and, cervical and ocular VEMPs, examines the dynamic.•SVV, with the bucket method, and cervical and ocular VEMPs, contribute to the assessment of vestibulopathies.•SVV and cervical and ocular VEMPs together, are advantageous to assess otolith disorders in Meniere’s disease. To evaluate otolith function by comparing the findings of the Subjective Visual Vertical, the cervical Vestibular Evoked Myogenic Potential and the ocular Vestibular Evoked Myogenic Potential tests in patients in the inter-crisis period of unilateral definite Meniere's disease. The sample consisted of an experimental group (n=22; 10 men and 12 women, mean age 47.32±12.82 years) with definite unilateral Meniere's disease and a control group (n=14; 5 men and 9 women, with a mean age of 41.64±13.45 years). They all underwent vestibular evaluation by means of Subjective Visual Vertical with the bucket method and, cervical and ocular Vestibular Evoked Myogenic Potential tests. The data were collected and subjected to statistical analysis. The results of the comparison of the Subjective Visual Vertical, the cervical Vestibular Evoked Myogenic Potential, the ocular Vestibular Evoked Myogenic Potential and, the association of cervical Vestibular Evoked Myogenic Potential with the ocular Vestibular Evoked Myogenic Potential showed no significant difference, indicating concordance among the tests. The identified abnormalities and the concordance between the combined proportion of the Subjective Visual Vertical, the cervical Vestibular Evoked Myogenic Potential and the ocular Vestibular Evoked Myogenic Potential findings indicate that the association of these three tests contributes to the identification of sustained and transient otolith dysfunction in the inter-crisis of unilateral definite Meniere’s disease. 2.
