Abstract:Facial synkinesis is the simultaneous contraction of the certain facial musculature accompanying a motion of designated muscle in the face. With the exception of rare afflictions that are congenital in origin, most patients develop as a sequel to facial nerve paralysis due to trauma, tumor, and surgical injury. As an idiopathic congenital form, oculo-nasal synkinesis which reveals co-contraction of orbicularis oculi and the compressor narium minor muscles which are innervated by separate branches of the facial… Show more
“…1 Congenital cases such as the Marcus Gunn phenomenon are rare in the population. 2 Most patients suffer from facial synkinesis owing to facial nerve paralysis. 3 The pathophysiology underlying facial synkinesis is complex.…”
Ocular–oral synkinesis refers to the unintended contraction of the perioral muscles during voluntary eye closure. This phenomenon can either be congenital or occasionally develop during recovery from facial palsy. In this study, we report a case of ocular–oral synkinesis without facial palsy after trauma.

A 4-year-old girl with maxillary hypoplasia, intermittent exotropia, and high myopia displayed congenital oculonasal synkinesis. We examine the implications for pathogenesis of these disparate craniofacial findings.
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.
