Hereditary familial forms of neuropathy of the facial nerve

: A total of 230 patients with facial neuropathies were under this study. Of these, in 29 members of 13 families the hereditary nature of the diseases transmission was clearly evident. The incidence of hereditary-familial form of the facial neuropathy was 12.6% with the rate of intrafamilial affliction being 23.3%. Two factors have been found to influence the morbidity: (1) genetic predisposition manifested by autosome-dominant type of temporal bone malformations; (2) exogenous factors leading to ischemia and compression of the facial nerve and thus promoting the phenotypic realization of genotypic predisposition.
