I can’t lift my upper eyelids up, and I have trouble opening my eyes, so I can’t open them much? Do you have wrinkles on your forehead when you open your eyes wide? When I open my eyes, I raise my eyebrows a lot? Can’t close your eyes fully when you sleep (leading to long-term exposure keratitis and dry eyes)? If any of these problems occur, then it is basically certain that you have ptosis. Ptosis is a drooping condition caused by partial or total inability to lift the upper eyelid due to incomplete or absent upper eyelid lift muscle function, or other causes. This can be corrected through surgery such as frontalis suspension and levator shortening. 1. Upper eyelid levator shortening surgery Upper eyelid levator shortening surgery: is used to shorten the levator muscle to achieve eyelid uplift to correct ptosis. The amount of shortening depends mainly on the strength of the levator muscle rather than the amount of ptosis. The amount of shortening generally follows the following principles: (1) 4-6 mm for every 1 mm of ptosis correction (2) 20-24 mm for congenital ptosis with a muscle strength of 4 mm (3) The amount of shortening for congenital ptosis should not be less than l0 mm (4) The amount of shortening for age-related ptosis should not exceed l0 mm. If the candidate has a single eyelid: the excess If you have a single eyelid, you can remove the excess skin, remove the orbicularis muscle, and suture the skin to the lid or the levator muscle to improve the ptosis and achieve the three-dimensional beauty of a double eyelid. Suitable for: patients with mild or moderate congenital, age-related, traumatic or other types of ptosis. 2. Frontal muscle flap suspension surgery Frontal muscle flap suspension surgery: the frontal muscle is cut off, the frontal fascial flap is separated, and the frontal muscle flap is fixed to the eyelid through suspension to correct the drooping upper lid. Suitable for: moderate to severe ptosis. Some people may choose to have double eyelid surgery to improve their sagging eyes, but is this okay? Let’s look at a set of comparison pictures: Ptosis is a muscle weakness that needs to be corrected with the appropriate surgery. The two are not the same surgery, but are usually done together. If you do double eyelid surgery alone, you just have a double eyelid crease after surgery, and the strength of the levator muscle does not get adjusted in any way. You can look at this picture in the middle, where the ptosis does not get effectively improved and the eyes still look godless.
