Ptosis occurs when the muscles that raise the upper eyelid (levator and Muller's muscle) get damaged. There are lot of ptosis correction surgery reported in the journals of oculoplastic surgery and opthalmic surgery. Most of these surgeries are cosmetic correction. Rarely ptosis can be seen as a complication following orbitozygomatic complex injuries. Cause of traumatic ptosis most often is levator detachment from the superior tarsal plate. Lacerations of the lid may sever the levator tendon leading to scarring and secondary mechanical ptosis. Challenge in surgical management lies in identification of Levator aponeurosis, posterior to orbital septum and preaponeuratic fat. Once the levator muscle is freed from scar tissue it should be reapproximated to tarsal plate.
