Abstract
The treatment of congenital ptosis with poor levator activity is often based upon the union of the superior eyelid to the frontalis muscle by using different materials as potential grafts. Nevertheless, theses grafts may lead some complications. In order to avoid them, a new technic has been described using an advancement flap of the frontalis muscle, that is tided to the upper tarsus, eliminating the need of a graft. Although, it is not yet a standard procedure, reason why many variants has been recently described with the objective of improve the aesthetical and functional results. The goal of this systematic review is to conscientiously evaluate these variants with the propose of determine which one gives the best results in terms of safety, functional and aesthetical outcomes. From the review of the published procedures, we conclude that the best technique in terms of functional and aesthetical results is: sub-orbicularis dissection via lid crease incision reaching the orbital margin, followed by blunt dissection of the frontalis muscle and creation of a "U" shaped flap (that might be associated to a levator advancement in severe cases), finally, the frontalis flap is stitched to the upper end of the tarsus taking care to maintain a symmetrical contour when compared to the contralateral eye. The final eyelid margin height should be 1.5 mm above the sclero-corneal limbus.
