Resection and advancement of the levator aponeurosis is a technique often used in correction of ptosis in patients with greater than 5 mm of levator function. This technique is performed via the exposure of the levator aponeurosis through an anterior approach, traditionally using an incision running the entire length of the upper eyelid crease, then advancing the levator aponeurosis by folding or excising the muscle, and reattaching the aponeurosis to the anterior surface of the tarsus. This method results in an elevation in the contour of the upper lid by effectively shortening the levator muscle itself. This approach has the advantages of preserving normal anatomical planes and structures of the eyelid as well as preservation of all elevating structures, including Mueller’s muscle and Whitnall’s ligament.
