[Causes of premorbid vascular insufficiency in patients with facial neuritis].

In 110 patients with facial nerve neuritis of different etiology, the author studied diseases which were accompanying the main disorder and those which were in the past history. In most of the cases there were infectious diseases and accompanying disorders of a vascular, endocrine character, diseases of the gastrointestinal tract and chronic tonsillitis. In some of the patients accompanying disorders were of a physiological condition (pregnancy, climacterium). On the basis of the specific traits of the above-mentioned diseases and physiological states which can accompany or lead to structural of functional changes of the vegetative nervous system and because of a vascular nature of some of them the author assumes that these diseases are the cause of permorbid vascular insufficiency in patients with facial nerve neuritis.
