VIDEO HEAD IMPULSE TEST AND CERVICAL VESTIBULAR EVOKED MYOGENIC POTENTIALS IN PATIENTS WITHMENIERES DISEASE

Menieres disease is a labyrinthine disease that usually presents with episodes of vertigo associated with sensorineural hearing loss, tinnitus and aural fullness. There is no specific Vestibular function test objectively used for diagnosis of the disease. Objective: Here, we compare findings of caloric test, cervical vestibular evoked myogenic potentials (cVEMP) and video-head-impulse test(vHIT) in patients with Menieres disease to assess which one is more sensitive test for diagnosis of Menieres disease. Methods: This study was carried out on two groups of subjects including 20 adult subjects with Menieres disease and 20 normal subjects free from any vestibular symptoms. Results: the most sensitive test was cVEMP (84.6%) followed by vHIT(75%) and then the caloric test(50%).Conclusion: The cVEMP test is the most sensitive test for diagnosing Menieres disease, We also found that the presence of catch–up saccades due to abnormal VOR reflex is an important sign that greatly aids the diagnosis
