Müllers muscle-conjunctival resection ptosis procedure.

The Müllers muscle-conjunctival resection procedure is a relatively simple means of relieving upper eyelid ptosis. Candidates for the operation are chosen by placing several drops of 10% phenylephrine hydrochloride into the upper ocular fornix. If the upper lid elevates close to a normal level after five minutes, the patient is selected for the operation. A specially designed clamp is applied to 6.5 to 9.5 mm of conjunctiva and Müllers muscle above the superior tarsal border. A suture is run distal to the clamp, connecting conjunctiva and Müllers muscle to the superior tarsal border, and then the tissues held in the clamp are resected. The Müllers muscle-conjunctival resection has advantages over the Fasanella procedure, because tarsus is preserved, and over the levator aponeurosis advancement and tuck procedures, because the results are much more predictable.
