Features of vestibular dysfunction in patients with vestibular neuritis

Abstract

Vestibular VN (VN) is the third most common in the structure of peripheral vestibulopathies. The study of the features of damage to peripheral vestibular receptors in vestibular neuritis using instrumental research methods (video head impulse test, registration of VEMPs) allows us to develop factors associated with the preservation of persistent peripheral vestibular hypofunction after the disease. On the basis of Sverzhevky Research Institute of Clinical Otorhinolaryngology examined 77 patients with vestibular neuritis (age 44,2±12,3 years, of which 37 were men, the duration of the disease until the moment of treatment was 3,2 ±1,7 days). There was a higher prevalence of total VN compared to superior VN (57 and 43%, respectively). Violation of the function of otolith receptors according to the data of registration of VEMPs was recorded in 46% (n = 35) patients with VN. The dynamics of vestibular function recovery in patients with superior VN was better than in patients with total VN (73 and 45%, respectively). Damage to otolith receptors detected by the method of registration of VEMPs was associated with worse dynamics of restoration of vestibular function in patients with vestibular neuronitis (p < 0,05).
