Definition:Unilateral ptosis with associated upper eyelid contraction and contraction of either the external or the internal pterygoid muscle. It is thought to occur because of congenital miswiring of a branch of the fifth cranial nerve into the branch of the third cranial nerve supplying the levator muscle. In Marcus Gunn jaw winking synkinesis, elevation and even retraction of the affected eyelid is triggered by chewing, suction, lateral mandible movement, smiling, sternocleidomastoid contraction, protruding tongue, Valsalva maneuver and even by breathing.
Synonyms:exact_synonym: Marcus Gunn jaw-winking syndrome;   Pterygoid-levator synkinesis;   Trigemino-oculomotor synkinesis
