The phenomenon of ptosis of the outer corner of the eye can be divided into true ptosis and pseudo-pituitary ptosis. True ptosis of the outer corner of the eye is when the bony structures of the orbit are lower on the outside than on the inside, and thus the attachment point of the external canthal ligament is lower as well. Pseudopendulous external canthus is a new, lower, pseudo-exophthalmos due to laxity and sagging of the facial skin, especially the upper eyelid skin, which partially obscures the external canthus. It looks like the outer part of the eye droops downward and the person appears unrefined. True ptosis requires moving the bones of the orbit to resolve the problem, which is more work and risky. For patients with pseudo-exophthalmos, we can remove the sagging skin on the outside of the eyes through double eyelid surgery to get a beautiful pair of eyes with a beautiful look while correcting the sagging of the outer corner of the eyes. Can multiple eyelids be surgically adjusted? Causes of Multiple Eyelids 1. Congenital protrusion of the eyeball, slightly sunken upper lid, thin and relatively large skin forming multiple folds of the heavy eyelid. 2, When doing double eyelid surgery, the design of the heavy lid line is lower than the normal heavy lid crease, and the excess upper lid margin before the skin builds up causing triple folds or multiple folds (some will appear). 3. As time passes, the loose upper lid skin builds up above the heavy lid line to form a triple fold or multiple folds. 4. The eyelid surgery process is very traumatic, and later triple folds or multiple folds are formed due to tissue adhesions. For multiple eyelids caused by the accumulation of loose skin, double eyelid surgery can be performed to remove the excess skin. For multiple eyelids due to surgical reasons, the problem of multiple eyelids can be solved by double eyelid restoration surgery, by precisely designing the height of the eyelid line and separating the adhering tissue structures. Therefore, by analyzing the reasons for the formation of multiple eyelids, a professional plastic surgeon is able to adjust the multiple eyelids into a beautiful pair of eyelids through double eyelid surgery.
