Levator sling for Marcus Gunn ptosis.
نویسندگان
چکیده
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.

The phenomenon is normally unilateral, but bilateral cases are not unknown. Its exact etiology is not known. We report a case of bilateral Marcus Gunn phenomenon. The ptosis is secondary to a conflict between the o...

A modified simple technique of brow suspension by using 4-0 Supramid (non-absorbable thread) suture and only one skin incision is described in 25 eyes of 15 cases of ptosis, including cases of congenital and mechanical ptosis and ptosis with Marcus Gunn phenomenon. This technique avoids the use of any special instruments such as the Reese ptosis knife and Wright needle.

Transcutaneous blepharoptosis surgery with simultaneous advancement of the levator aponeurosis and Müller's muscle (levator resection) is a popular surgery which is considered effective for all types of blepharoptosis except for the myogenic type. Repair of ptosis cases with good levator function yields excellent results. A good outcome can be also obtained in cases with poor levator function, ...
