Marcus Gunn Jaw-Winking Phenomenon: management and results of treatment in 19 patients.

From 1980-1995, 19 patients displaying the Marcus Gunn Phenomenon (MGP) were treated in the Department of Maxillofacial Surgery of the Jagiellonian University in Kraków, Poland. Sixteen patients were operated on according to the Neuhaus method, in one case bilaterally. In three patients, the upper eyelid, after partial transsection of the levator muscle, was suspended from the frontal muscle on autogenous temporal fascia strips. At postoperative follow-up, the width and symmetry of the palpebral fissures were evaluated as well as persistent symptoms of synkinetic eyelid movement. In 13 (68.4%) patients, proper width and symmetry of the palpebral fissures were obtained, whereas in the remaining six (36.1%) marked improvement and decreased asymmetry of palpebral fissures were achieved. Pathological synkinesis disappeared totally in 16 (84.2%) of the patients on operated.
