Familial recurrent cranial nerve palsies

ABSTRACT- Family cases of recurrent cranial nerve palsies are seldom reported. This paper presents a family with recurrent facial and ocular nerve palsies in 2 brothers. Their father and his sister had Bell's palsies. Examinations provided no explanation. Six previous reports of families with recurrent cranial nerve palsies are summarized. The pedigrees speak in favour of an autosomal dominant mode of inheritance of predisposing factors. The pathogenetic mechanism might be vascular or autoimmune, but is still unknown.
