Improved Technique for Fascial Sling Reconstruction of Severe Congenital Ptosis

Abstract

Fascial sling surgery for severe congenital ptosis yields superior results when the operative result is dynamic rather than merely suspensory. The sling itself is attached as in a tendon transfer solely to the frontalis muscle, minimizing adherence to the underlying periosteum and the overlying dermis. The sling is passed behind a pulley created by the superior transverse ligament so as to produce a more normal vector of pull. The dermis of the skin is attached to the sling to create a dynamic supratarsal crease. Postoperative retraining allows the patient to achieve more than one centimeter of levator function. These operative modifications make this procedure more closely parallel the normal eyelid dynamics and yield consistently good results for this difficult problem.
