The precise design positioning of the double eyelid line is only a small step before surgery, because the design line is only an important factor in determining the width of the double eyelid. In clinical practice, such a situation often occurs. The line design of the eyes on both sides is basically the same, but the width of the lines after the operation is different. Sometimes the design lines on the two sides are obviously different, but the width of the double eyelid line is basically the same.  . Next, I will analyze the factors that determine the width of the double eyelids. The factors of the skin suture position are often written in textbooks 6-8mm to explain the design width range of the double eyelid. In fact, there are many factors that determine the width of the double eyelid, and it is not as simple as drawing a line. The pre-operative design line is to determine the location of the stretched skin, which is very close to the width of the double eyelid. Within a certain range, the higher the design position, the wider the double eyelid fold line.  . . 2. Factors of the levator muscle or meibomian suture position (including the levator muscle opening and closing factor) in addition to the design of the point of care, the muscle strength of the levator muscle also has a very important effect on the width of the double eyelid and folds.  . When the levator displacement is different, the width of the double eyelid line is also different. 1. When the normal muscle strength is open, a deep double eyelid fold is formed; when the levator muscle is weak, the mobility is poor, and the double eyelid line is shallow and wide. Patients with ptosis cannot form a deep double eyelid fold, which is the reason for the insufficient displacement. In other words, although the double eyelid fold is relatively wide, it appears to be inexplicable due to the low corneal exposure rate!  . Under normal muscle strength, even if the design line of the double eyelid is the same, if the position of the levator muscle or the eyelid plate is different, it may result in a different width of the double eyelid. three. The factor of skin peeling amount has a great influence on the width of double eyelid. Under the premise that the muscle strength is normal, the design line of the double eyelid is the same, and the position of the levator muscle or the eyelid plate is the same, the more loose the skin, the more the upper lip skin covers the lower lip skin after reflexion, the more the double eyelid fold line appears narrow. It can be seen that, within the limit and reasonable range, the greater the amount of peeling during double eyelid surgery, the wider the double eyelid width.  . Factors of the volume of the lower lip tissue . The height difference of the eye is limited by the fold line of the double eyelid, the relative height of the incision upper lip (the area between the double eyelid line and the eyebrows) and the lower lip (the area between the double eyelid line and the eyelashes) . Generally, the upper lip should be higher than the lower lip: the upper lip is slightly thicker, forming a sense of high-land fold, and the lower lip is easily folded into the upper lip, forming a natural and beautiful double eyelid appearance.  . Factors of tightness of incision adhesion The more firmly the double eyelid incision is adhered, the firmer the site of suture and attachment point is. Whether the thread is buried or the double eyelid is cut, the tissue of the adhesion site will gradually relax and shift downward. That is, the position of the fixed point of the double eyelid suture is also moved downward, and the width of the double eyelid will be narrowed. The double-embedded thread is most likely to loosen because the scar is lightly adhered and the nylon thread is cut.
When many people plan to do double eyelid or repair, they are told by the doctor that there is a ptosis, and they will ask the beautician to provide a picture before the operation to determine whether the levator muscle is damaged during the congenital or acquired surgery. Congenital ptosis is also more common. Many people have large and small eyes. Excluding the length of the eye cracks. The exposure of the pupil on one side will always be worse. If the doctor does not Without realizing this problem, it is easy to have the same width of the double eyelid after the operation, but there is a situation where the double eyelid on one side is too shallow and the eye is open and the asymmetry is involved. For example, this customer has congenital right eye ptosis, long-term eye opening power error, and the best correction timing results in weakened vision. The naked eye power of the two eyes differs by nearly 300 °, and the eye with ptosis is obviously present The degree of myopia is a little higher, reaching 900 °. So remind the babies that if they find that the baby has ptosis in their early childhood, they can be treated in time, not only for beauty, but also for health. 2. Acquired drooping of the eyelid is generally caused by, for example, a car accident, resulting in damage to the eye muscles, or when the doctor touches the levator muscle layer during double eyelid surgery, it will cause damage to the levator muscle, which will cause large and small eyes In the case of late double eyelid repair, attention should be paid to repair. For example, this customer has already had 2 double eyelid surgeries, and there is a slight ptosis. After cutting the loosely attached muscle tissue, it is found that the levator muscle is incomplete. To repair this situation, it needs to be peeled to the deep layer of the levator muscle. Use CFS combined with fascia sheath technology to repair. & nbsp. The next article will analyze how to choose the three surgical methods for ptosis correction. Remember to pay attention.
Many beauty seekers may wonder how the eyelid is formed by surgery. First, let’s understand the reasons for the formation of double eyelids. Medically, the muscles that open the eyes are called the levator levator. For people with congenital double eyelid, the fibers of the levator muscle of the upper eyelid are not only attached to the upper edge of the eyelid to open the eye, but also some fibers pass forward through the eye wheel. The orbicularis muscle, attached to the upper eyelid skin, is 4 to 7 mm from the eyelid margin. When the eyes are opened and the levator muscles of the upper eyelid contract, the skin in this area is pulled upwards, and the upper part of the skin is relatively sagging, so that a skin fold is formed, which is a double eyelid fold, also known as a double eyelid. Those with a single eyelid generally have no fibers attached to the eyelid skin and no wrinkles. Any method of double eyelid formation-either surgical or not, is to form this connection. Without the connection between the skin and the levator muscle of the upper eyelid, there is no double eyelid. For example, it is like a thin curtain hanging, and the bottom half of the curtain is sewed and fixed with a thread. When the fixed thread is pulled up, wrinkles appear in the lower half of the curtain. After the curtain is pulled, there is a certain gap from the ground, which is why the eyes become larger after the double eyelid surgery. But if the curtain is very wide, when the curtain is pulled up, the upper part of the fixed point will cover up the wrinkles. This is why it is not easy for people with loose eyelids to perform suture and embedding double eyelid surgery. If the curtain is a thick quilt and you still pull the curtain at the same height, you will find that the upper part will bulge into a thick bag, and the lower part will be wider than the thin quilt The reason why people with thick eyelids should remove fat and muscles during the operation, and the design line of the double eyelid is low. What are the types of double eyelid? Parallel type: The eyelids of the double eyelid and the upper eyelid are basically parallel. The design of the double eyelid line, the outer side should not exceed the outer corner of the eye. This form is suitable for women with large eyes, high eyebrow arches, long eyebrows away from the eyes, and thin upper eyelids. Fan type: This is also one of the most classic double eyelids, similar to “peach blossom eye”, which is popular with young girls. It is characterized by a narrow inner and outer width, suitable for a moderate distance between eyebrows and eyes, thin eyelids, a certain angle between the horizontal axis of the eyes and the ground plane, and a slight upward lift of the outer corners of the eyes. Inner width and outer narrow type: suitable for no skin of inner canthus, eyebrows and eyes are relatively close, Western women are more common. If it is serious, it will form a “triangular eye” -like appearance. Flat-fan type: It has the characteristics of parallel and open-type double eyelids. The inner half is slightly open, while the middle and outer sides are mainly parallel. Many women now favor this form. European style: that is, the double eyelid is extremely wide and the fat is completely removed. Basically, it is only suitable for the skeletal structure of the European face, which is also determined by the physiological anatomy of the eyelid and lid. Moreover, their eyebrow arches are particularly high and their eyebrows are close to their eyes, so their eyelids are often wide and exaggerated. But this is not very suitable for Oriental girls.
