Levator sling for Marcus Gunn ptosis.

A modified simple technique of sling operation is presented in 15 cases using the levator aponeurosis as the material for the sling as originally devised by Lemagne and Bemcher. The levator is cut behind the superior transverse ligament and the posterior part of the levator is cauterised and allowed to retract into the orbit. The horns are cut from behind forwards, and the levator, which is kept attached on the tarsal plate, is used to lift up the lid. This method eliminates the jaw winking phenomenon as well as lifting the lid.
