Marcus Gunn jaw winking synkinesis (MGJWS) occurs due to an aberrant innervation of the levator palpebrae superioris muscle by a branch of the motor division of the trigeminal nerve that supplies the muscles of mastication. MGJWS is mostly unilateral occurring in isolation and is less frequently associated with ocular or systemic abnormalities. Although MGJWS is mostly unilateral, few bilateral cases have been reported. Here we describe a rare case of bilateral MGJWS in an 18 year-old male patient with asymmetric bilateral ptosis and monocular elevation deficiency in the right eye.
马库斯·冈恩氏下颌瞬目联带运动（MGJWS）是由于三叉神经运动分支的一个分支异常支配提上睑肌所致，该分支为咀嚼肌提供神经支配。MGJWS大多为单侧发生，孤立出现，较少与眼部或全身异常相关。虽然MGJWS大多为单侧，但也有少数双侧病例的报道。在此，我们描述一例罕见的双侧MGJWS病例，患者为18岁男性，存在不对称性双侧上睑下垂及右眼单眼上睑提升不足。
