Abstract:

Marcus gunn jaw-winking syndrome（MGJWS） is a rare kind of facial synkinesis which is manifested as mandibular-eyelid synkinesis,   usually accompanied with blepharoptosis. Developmental ocular diseases may be caused since ptosis occluding the visual axis,   and the jaw-winking phenomenon may cause some psychological issues. Thus, early intervention is essential. At present, several operation methods, including modified levator plication, anastomosis of levator with frontal muscles and frontalis suspension with levator disabling, have been proposed toward the main two symptoms of MGJWS, jaw-winking synkinesis and blepharoptosis. Still, there’s no common consensus on which surgical method is the most optimal solution for MGJWS. Researches discovered that operation is not essential for every patient. For mild MGJWS, observation should be considered first. Operation is recommended for moderate or severe MGJWS and patients who present persist function problems or appearance issues. At present, unilateral levator excision and frontalis suspension is an ideal surgical method since its convenience, less anatomy destruction and steady postoperative effect.
