The review of the literature on RSCI and PubMed databases presents methods of electrical vestibular stimulation to improve vestibular function in patients with bilateral vestibulopathy. The variants of stimulation of peripheral vestibular structures, such as vestibular implantation, noise galvanic vestibular stimulation are described. The perspectives of development of this direction, advantages of application of electrical stimulation in the future, as well as current limitations that do not currently allow to use these methods in clinical practice are shown.

The literature review is devoted to the practical application of the method of recording vestibular evoked myogenic potentials (VEMPs) in the diagnosis of the inner ear diseases: superior semicircular canal dehiscence syndrome, Meniere's disease, benign paroxysmal positional vertigo (BPPV), vestibular neuritis. Registration of VMEP is an electrophysiological research method that allows to assess objectively the functional state of the otolith receptors (sacculus and utriculus) and their pathways, which expands the diagnostic capabilities in diagnosis of the inner ear diseases.

The literature review is devoted to the effects arising from the effect of a cochlear implant on the vestibular system. Due to the pronounced anatomical proximity and physiological interaction of vestibular receptors with the cochlea, the installation of a cochlear implant and its electrical activity are associated with an effect on the vestibular system. The analysis of the works of foreign and domestic researchers who carried out monitoring of vestibular function in patients after cochlear implantation using modern objective methods was carried out.

The results of magnetic resonance imaging (MRI) of the inner ear 24 hours after intratympanic administration of 1 ml of diluted (1:7) contrast substance for gadolinium-based MRI in 43 patients with moderate and severe Meniere's disease course are presented. It has been revealed that in case of severe and moderate course of Meniere's disease endolymphatic hydrops is presented in all departments of labyrinth: cochlea, vestibule, semicircular canals, but is most pronounced in vestibular department of labyrinth: horizontal semicircular canal and vestibule. The neuroimaging method according to the presented protocol is safe and can be applied in a wide practice both to assess the presence and localization, and the degree of expression of the endolymphatic hydrops.
