RODRIGUEZ PEINADO, Nazareth; MOURELLE MARTINEZ, María Rosa  and  DIEGUEZ PEREZ, Montserrat. Marcus Gunn syndrome. Rev Cubana Pediatr [online]. 2020, vol.92, n.2, e912.  Epub Apr 15, 2020. ISSN 0034-7531.


Marcus Gunn syndrome manifests with retraction or elevation of the eyelid ptotico while stimulation of the pterygoid muscle on the same side and the term jaw-winking is inappropriate because the eyelid does not always goes down. It can occur during mouth opening, mastication, mandibular advancement, while smiling, whistling, bruxing, sticking out the tongue, swallowing, sucking, singing, during the sternocleidomastoid contraction, the Valsalva maneuver, breathing or inhaling. This syndrome is congenital and rare, and of autosomal dominant modality.


To contribute to the knowledge of this rare disease and its relationship with the odontologic field.

Presentation of the case:

3 years old boy diagnosed with Marcus Gunn syndrome in the neonatal period by the observation of the mother of a left palpebral opening during the nutritive sucking. He does not present other diseases or a background of interest. In the extraoral exploration, it is noticed a right palpebral ptosis and a left palpebral opening in the jaw movements and in swallowing. The intensity of the reflex increases in anxiety states arising from the dental treatment.


Marcus Gunn syndrome is a rare entity in pediatrics, in which its clinical findings determine the diagnosis. Taking into account that sometimes it presents ocular alterations, nothing makes us suspect the presence of a specific oral disease.

Keywords : Marcus Gunn syndrome; facial synkinesis; dental treatment.
