The dropping of the upper eyelids is one of the most complaints in oculoplastic practice. Other related complaints include
difficulty seeing due to the attendant visual field obstruction and prefrontal headaches due to chronic use of the frontalis muscle in an attempt to lift the eyelids. This anatomic and morphologic state is termed ptosis, from a Greek, to fall. Ptosis causes a simultaneous cosmetic deformity that is apparent both to the patient and to others.

Ptosis surgery can be challenging for even the most experienced eye and facial plastic surgeon. The correction of ptosis of more complex etiology and congenital ptosis may even be more elusive. To minimize reoperations and maximize postoperatively
symmetry, detailed preoperative assessment, and intraoperative anatomic dissection with respect to tissue planes and hemostasis
are necessary.
