ABSTRACT
In order to analyze the phenomenon of neurovascular conflict a series of studies was conducted. In the course of the dissection part (12 block preparations of the posterior fossa) we determined the frequency of neurovascular conflict occurrence. Histological analysis of intracranial part of the 8th nerve (8 samples of the left and right vestibulocochlear nerve) revealed differences in morphostructure of cochlear and vestibular part of the nerve. The article describes the change of mutual arrangement of the cochlear and vestibular nerve from the internal auditory meatus to the lateral surface of the brain stem, develops the technique of MRI studies, which makes it possible to visualize the 8th nerve and adjacent vessels without introduction of contrast and investigates MRI characteristics of 27 patients with unilateral/asymmetric cochleovestibular manifestations.
