title: Incidence of bilateral Marcus Gunn jaw-wink.
abstract: This case report describes the unusual finding of bilateral Marcus Gunn jaw-wink. Only a few bilateral jaw-wink patients have been published as case reports. The authors dispute this notion as portrayed in the literature that a bilateral wink is a rare entity. A thorough review of prior case series on congenital ptosis and jaw-wink demonstrates that bilateral involvement is more common than previously thought. A supplemental video shows the classic action of lateral pterygoid contraction causing ipsilateral eyelid retraction.
