Synkinetic movements of the upper eyelids may be noted in association with movements of either extraocular muscles or other muscles of the face. Patients with oculopalpebral or facial-palpebral synkinesis may also have ptosis of the involved eyelid. The clinical and therapeutic features of this association are specific. We mainly distinguish two forms of synkinetic movements, characterized either by the elevation of the ptotic eyelid such as in Marcus Gunn phenomenon and in the Fuchs sign or by the falling of the upper lid such as in Marin Amat syndrome. Many surgical techniques have been used to correct the blepharoptosis and the synkinetic movement. Levator resection is often advocated for correction of blepharoptosis with a mild degree of synkinesis. However, when the ptosis is major, eyelid lag is a possible outcome. For moderate or major synkinesis, bilateral frontalis suspension with disinsertion of the levator has been suggested. This procedure generally provides satisfactory cosmetic results.
