The Otolithic Tests Results (SVV, SVH, and cVEMP) in Patients with Definite Meniere's Disease

Menier is a disease of internal ear that involves cochlea and otolith organs, which play important roles in the balance of body. Cervical Vestibular Evoked Myogenic Potential (cVEMP), Subjective Visual Vertical (SVV), and Subjective Visual Horizontal (SVH) are tests to evaluate otolith organs. Understanding otoliths functions and choosing the appropriate test to evaluate them can help control and treat menier’s disease. The purpose of the present study was to collect and integrate the results of studies that investigated the otolith organs in Meniere's disease patients using three tests of cVEMP, SVV, and SVH.
PubMed, Elsevier, and Google Scholar database were searched using “menier”, “Otolith”, “Saccule”, “Utricle”, “cVEMP”, “SVV”, and “SVH” keywords. A total of 45 articles relevant to the topic were selected and studied.
Generally, otolith tests have limited sensitivity and specificity. cVEMP shows abnormal results in menier’s disease that is almost independent of the duration of disease. SVV has good performance in acute phase of menier’s disease. In the acute phase of the disease, it shows error to the set line vertically and deviated to the affected side. About SVH, no remarkable report was found.
