Abstract:Clinical findings from 35 patients with isolated paralyses of distinct branches of the facial nerve are demonstrated. Presumably because of its position, the mandibular marginal ramus has most often been affected (n = 21) followed by buccal (n = 6) and temporal branches (n = 4). In two patients, the pattern of perioral muscular pareses was compatible with lesions of more than one branch. Causes for the facial nerve branch lesions were iatrogenic (n = 25), tumor (n = 4), trauma (n = 2), inflammatory (n = 1), id… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
