Marcus Gunn jaw winking phenomenon has been thought to result from a congenitally abnormal innervation of the levator palpaebrae muscle by a branch of the trigeminal nerve. A 22-year old man presented with bilateral eyelid elevation on the chewing or eating since infancy. Neurological examination showed bilateral Marcus Gunn Jaw wingking phenomenon in this patient. We referred this patient to the department of ophthalmology and plastic surgery for levator resection or orbicularis oculi muscle flap. We report bilateral Marcus Gunn jaw winking phenomenon, although unilateral disorder is the most common form of trigemino-oculomotor synkinesis. Neurologists should be aware of this phenomenon for decision of proper management and take detailed neurologic examination for elucidating the association of other cranial nerves.
Key words: Marcus gunn jaw winking syndrome, Ocular miswiring
