What design diagnosis is needed for the surgeon before double eyelid surgery! In addition to the surgeon’s operation and post-operative care, the patient’s own condition is also an important factor in the effect of the surgery and an important basis for choosing the type of eyelid surgery you will undergo. Ptosis is formed when the function of the upper eyelid lifting muscle is partially or completely lost, which can cause obstacles to open the eyes. Depending on the degree to which the eyelid covers the pupil, ptosis is categorized as mild, moderate, or severe. People with severe ptosis cannot have double eyelid surgery and can only be corrected with surgery such as frontalis flap suspension and levator palpebral muscle shortening. Here need to remind, some people because the eyelid too loose cover the pupil, definitely not ptosis, do not go to do ptosis corrective surgery, this situation as long as to do a peel double eyelid surgery on the solution. 2, canthus is a piece of vertical skin fold in the inner corner of the eye, divided into light, medium and severe, mainly affecting the formation of double eyelid at the inner corner of the eye. The solution is to open the inner corner of the eye. The satisfaction rate of eye opening is very low, scars will be seen in the short term, and not all people are suitable for eye opening. Only people with a very large inner canthus and a great distance between the two inner corners of the eyes are suitable for eye opening surgery. Some people have a low, flat nose, which makes the distance between the eyes too wide, so they only need to have rhinoplasty, and do not need to open the inner corner of the eye. 3, swollen eyes Often people with swollen eyes are characterized by thick fat, thick muscle and thick skin. Double eyelids for these eyes are very difficult to do, and require the doctor to have extensive experience. Simply thick fat is the best result and the best solution, just remove the excess fat. If the muscle and skin are thick, it requires the doctor to do special treatment during design and surgery. 4, upper eyelid skin laxity Upper eyelid skin laxity will affect the shape of the double eyelid, serious laxity and sagging will affect the vision and eyes, often give a person the feeling of fatigue, this situation in the upper eyelid of the outer 1 / 3 part is particularly obvious. The solution is to remove the excess skin, which is very effective. Because as people age, the skin will have different degrees of laxity, where you can not be too conservative when doing double eyelid surgery, especially the outer 1/3 of the part. 5, orbital septum fat or tear gland ptosis The fat of the orbital septum of the upper eyelid mainly has three groups: inner, middle, and outer, and the eyelid will be swollen and spiritless if the fat is too much, and in serious cases, the outer fat group will be out of the orbital septum, aggravating eyelid laxity. When the upper eyelid is loose and swollen, it is necessary to pay attention to the difference between the fat and the lacrimal gland, and the surgical process can be given appropriate removal or reset. 6, the width of the eyelid upper eyelid lid are tougher, its normal width of about 10mm, individual in 7-8mm below. The width of the eyelid is something that the surgeon needs to pay attention to before the surgery, because the width of the eyelid determines the maximum of the double eyelid, and the width of the double eyelid design generally should not exceed the upper edge of the eyelid. Many people have difficulty opening their eyes after surgery because the double eyelid line exceeds the upper edge of the eyelid plate or because of the adhesion of the levator muscle. 7, short eye cleft generally speaking, short eye cleft people are not suitable for double eyelid surgery, eye cleft relatively short people can not do double eyelid too wide. For short eye cracks many people will think of opening the inner and outer corners of the eyes, in fact, eye surgery will have a certain retraction, there may also be deformed eyes, not all people are suitable. Because there is no extra skin available in the corner of the eye, so most of them can not be repaired, belonging to the surgery without a way back, I hope that the preoperative caution. 8, eyebrow-eye spacing From the aesthetic standards, this is considered from the perspective of the overall coordination of beauty to consider, while taking into account the eyebrow, eye shape and the coordination of the entire face. Eyebrow-eye spacing is close, double eyelid can not do too wide; on the contrary, eyebrow-eye spacing is far, choose the moderate atmosphere of the double eyelid, will not look unnatural. Individuals in the middle-aged and elderly because of facial skin laxity, eyebrow sagging is more serious, excessive laxity of the upper eyelid skin affects the shape of the double eyelid, the formation of what is often referred to as “triangular eyes”. If corrected by blepharoplasty, it will only aggravate eyebrow ptosis, further narrowing the distance between the eyebrows and the eyes, and also destroying the transition relationship of the upper eyelid skin from the bottom to the top of the eyelid gradually thickening, so that the upper layer of the eyelid is even more bloated. Therefore, people with drooping eyebrows should first correct the problem of drooping eyebrows through brow lift surgery or forehead wrinkle surgery to restore the normal brow-eye spacing to improve the blepharoplasty problem.
