Scars are usually located on one side of the eyelid. During the operation, the shape of the healthy side should be fully considered, and the balance should be achieved as much as possible. It looks natural and the upper eyelid is loose. Scar generally does not cause ectropion, and it should be avoided when repairing eyelid scar. Small scars on the upper eyelid can be removed and sutured by plastic surgery. Skin grafting is needed after extensive scar excision. From the beauty point of view, you can do double eyelid surgery while trimming the upper eyelid scar. The principle is: reduce surgical scars and try to be symmetrical with the healthy side. The advantage of double eyelid surgery while removing the upper eyelid scar is that the surgical scar can be partially hidden in the double eyelids, and the double eyelids can be as symmetrical as possible.
