Eye plastic surgery is an operation to widen the width of the eye and make it look bigger by making an incision in the outer corner of the eye . By widening the width of the eyes on the outer corners of the eyes, it is possible to make the eyes look long and impressive, to lead to eyes with a gentle curve, and to improve the slanted eyes and small eyes. I will.

There are two main types of incision in the outer corner of the eye, and each has different characteristics such as the method of incision and changes in the finish, so it is important to understand the characteristics of each operation in advance when considering surgery . .. In addition, since the range of the outer corner of the eye that can be incised by surgery is limited, it may be difficult to feel a change in appearance only by surgery for outer corner of the eye, and depending on the finish that you want, such as inner canthus incision or double plasty. A combination of other surgeries may be required.

It is for me to understand the mechanism of widening the width of the eye by the outer corner of the eye, the content of the surgery, the downtime after the surgery and the guideline of the progress, and also to know the effect obtained by combining the surgery that can be used together with the outer corner of the eye. It leads to a better eye shaping choice .

Surgical incision on the outer corner of the eye to widen the width of the eye

Surgical incision on the outer corner of the eye to widen the width of the eye

Surgery to widen the outer corner of the eye by making an incision or partial excision of the skin and mucous membrane of the outer canthus, which means the outer corner of the eye, is called an incision .

Immediately outside the subcutaneous outer canthus if there is bone of the face of the orbital bone surrounding the eye (GankaKotsu), between the lateral canthus and orbital bone and a small pocket of conjunctival fornix portion, this is outside corner incision By making an incision in the skin that covers the pocket (conjunctival fornix), the white of the eye hidden by the outer corner of the eye is exposed .

By making an incision in the skin on the outer corner of the eye that covers the conjunctival fornix, the width of the eye looks wider, and by creating a gentle curve on the outer corner of the eye, it is possible to improve the hanging eye and lead to a gentle impression . In addition, you can expect the effect of making your face look smaller by expanding the width of your eyes to the outside. In surgery for outer corner of the eye, the outer corner of the eye is incised to physically widen the width of the eye, so the duration of the effect after surgery is basically semi-permanent.

An incision in the inner corner of the eye can be performed by both single and double eyelids, but it is an operation to widen the width of the eye by incising the skin on the outer corner of the eye, and it has the effect of enlarging the eye itself. The effect of forming heavy eyelids cannot be expected.

Trouble that can be expected to improve by incision of the outer corner of the eye

Regardless of gender, those who meet the following items tend to have an incision in the outer corner of the eye. However, depending on the original shape of the eye and the desired finish of the eye, an incision in the outer corner of the eye may not be suitable, so it is necessary to have a doctor diagnose whether surgery is indicated.

  • I want to increase the width of my eyes
  • I want to make it a long-sleeved eye
  • I want to improve sagging eyes and hanging eyes
  • Long distance from the corners of the eyes to the temples
  • My eyes are small and my face looks big
  • I want to widen the width of my eyes while keeping the single layer
  • I want to improve the laterality of the eyes
  • I want to improve mild exotropia (when the black eyes are facing outward)

Those who may be diagnosed as not suitable for incision of the outer corner of the eye

Those with narrow pockets at the corners of the eyes

There are individual differences in the size of the conjunctival fornix (about 1 mm to 6 mm) of the pocket between the external canthus and the orbital bone. Since incision of the inner corner of the eye is an operation to increase the exposure of the white of the outer corner of the eye by incising the skin of the conjunctival fornix, it is difficult to realize the postoperative effect because there are few parts that can be incised if this pocket is originally narrow. You may be diagnosed with maladaptation.

Even though the pockets on the outer corners of the eyes are narrow, if you try to forcibly widen the incision site, the mucous membranes on the outer corners of the eyes will be exposed, which may lead to unnatural finishes in the eyes. If you have been diagnosed, ask your doctor to suggest another eye plastic surgery for advice. / p>

Those who do not want to have long eyes

Just as pulling the outer corners of the eyes outward with your fingers narrows the vertical width of the eyes, making an incision in the outer corners of the eyes may make the vertical width appear narrower and give the impression of a long cut. If you want to widen the width of the eye but do not want to have a long cut, you can combine other operations such as incision of the inner corner of the eye and formation of sagging eyes (glamorous line) to make it more ideal. It is said to be approaching.

Those who do not want to increase the exposure of white eyes with Sanpaku

If you have Sanpaku eyes (where you can see the white eyes under the black eyes), making an incision in the outer corners of the eyes may increase the exposure of the white eyes on the outer corners of the eyes, making the Sanpaku eyes more noticeable . Therefore, it can be said that those who do not want to increase the exposure of the white of the eye are not suitable for the operation of the inner canthus.

Two main types of incision in the outer corner of the eye and their characteristics

Two main types of incision in the outer corner of the eye and their characteristics

There are two main types of incision in the outer corner of the eye, and in most cases, the "VY flap method" or "W method (Uchida method)" is used. The doctor will select the most suitable surgical method according to the original shape of the eyes and the ideal finish of the eyes, which are different for each person. Below, we will explain the characteristics of each of the two types of techniques.

"VY flap method" that incises and sutures the skin and mucous membranes of the outer corners of the eyes

The most commonly used surgical procedure for incision of the outer corner of the eye is the VY flap method, in which the skin of the outer corner of the eye and the mucous membrane under the skin are incised and then the incision site is sutured and fixed.

The basic procedure is to make a lateral incision in the skin and mucous membrane of the outer corner of the eye that covers the conjunctival fornix in a Y-shape of the alphabet to increase the exposure of the white eye on the outer corner of the eye and widen the width of the eye. , Sew the incision site in a horizontal V shape using suture and fix it.

After surgery, swelling occurs for about a week as downtime, and slight redness tends to continue for about 1 to 3 months at the incision site. In addition, since the VY flap method is a surgical method that finishes only by incision and suturing without excision of excess skin tissue, the difficulty of the procedure required for the practitioner is lower than that of the next "W method", and the surgery Although it is said that the time required for surgery is short, there is a possibility that the healing power of the skin will work after surgery and the condition will return to the state before surgery.

"W method (Uchida method)" to remove and suture excess skin

The W method is also called the "Uchida method" after the name of the inventor. The basic procedure is to make a lateral incision in the skin and mucous membrane of the outer corner of the eye that covers the conjunctival fornix in the shape of a W in the alphabet, remove the excess skin, and then make an incision in the triangular skin. By spreading the valve up and down and suturing it with the skin on the outside (outer corner of the eye), in addition to widening the width of the eye, the width of the top and bottom is also adjusted .

Compared to the VY flap method, the difficulty of the procedure required of the practitioner is higher and it is said that the difference in finish due to the technique is more likely to appear, but since the skin is excised, the natural healing power of the skin makes it possible to use it after surgery. It is said that there is little risk of backtracking to return to the state of .

In addition, after surgery, swelling for about 1 week and slight redness for about 1 to 3 months appear as symptoms of downtime like the VY flap method, but the W method is not limited to the width of the outer corner of the eye, but the upper and lower sides. Since the width can be adjusted slightly, it is said to be a surgical technique that tends to give a natural finish.

Compare the characteristics of the VY flap method and the W method

Incision procedure for the outer corner of the eye VY flap method W method
Method After making a lateral incision in the skin and mucous membrane of the outer corner of the eye in a Y shape, suture in a horizontal V shape. A W-shaped lateral incision is made in the skin and mucous membranes of the outer corners of the eyes, and the excess skin is removed before suturing.
merit Compared to the W method, the difficulty of the procedure is said to be low, and the time required for surgery is short. Since the skin is excised and sutured, the risk of backtracking is low and the finish tends to be natural.
Demerit There is a possibility of relapse due to the healing power of the skin Compared to the W method, the procedure is said to be more difficult, and differences in finish are likely to occur, and the time required for surgery is long.

Types of thread used for incision of the outer corner of the eye

The thread used to suture the incision during surgery for the outer corner of the eye varies from medical institution to medical institution, but is often made of nylon . Nylon sutures are said to be less prone to foreign body reaction in the body, and have been used for many years not only in cosmetic medicine but also in surgical operations.

In addition, the inner canthus is removed about one week after the surgery, but depending on the medical institution, the operation may be performed with an absorbent suture that does not require thread removal. If you are uncomfortable with foreign matter remaining in your body, consider surgery at a medical institution that removes threads.

In addition to black and blue as the color of the thread, some medical institutions use transparent thread that is inconspicuous in cases where the thread is not removed, but in each case it is said that there is little concern that it will be conspicuous because it uses ultra-fine thread. The fineness of the thread is "6-0", which is a little thicker than the hair, "7-0", which is about the same thickness as the hair, and "8-0", which is thinner than the hair.

Points when deciding the finished design by incision in the inner corner of the eye

Determine the design with reference to the golden ratio of the eyes

It is important to convey the desired image of the eyes to the practitioner, as there will be time to decide the finished design in advance when undergoing surgery for the outer corner of the eye. When the concrete image of the finish is not decided, the standard of design is the "golden ratio of the eyes" , which is the balance between the vertical and horizontal widths of the eyes, which is generally considered to look beautiful, and the vertical of the eyes. The balance between the width and the upper eyelid is expressed as follows.

Golden ratio of eyes

The golden ratio around the eyes, which is generally considered to look beautiful, is "width of the left eye: width between the inner corners of both eyes: width of the right eye = 1: 1: 1". By fine-tuning the design based on this standard, you can aim for a finish of the eyes that suits your facial features, and by widening the width of the eyes on the outer corner of the eye by incising the outer corner of the eye, the balance is adjusted to a balance close to the golden ratio. It is possible .

A more ideal design by combining an incision in the outer corner of the eye with other surgery

Although the outer corner of the eye can make the width of the eye look larger naturally, it is also said to be an operation in which it is difficult to feel the change in appearance, and depending on the ideal finish of the eye, other eye plasty may be used together. Is required. If you want to change the width of the outer corner of the eye, for example, the formation of double eyelids or the width of the inner corner of the eye, you need to combine other eye shaping techniques.

In the following, we will explain the tissues and roles around the eyelids related to the surgery performed in combination with the outer corner of the eye, and the changes that can be expected by using each surgery together.

Tissue around the eyelids involved in surgery

Frontalis muscle
The muscles located on the forehead from above the eyebrows have the role of raising the eyebrows.

Orbital fat (cancer)
It is a fat that protects the eyeballs, and when it hangs down due to aging, it causes dents and sagging of the eyes.

Orbicularis oculi muscle
A facial muscle that surrounds the eyes and is mainly used when closing the eyelids.

Levator palpebra (Gankenkyokin)
The muscles that open the eyelids by contracting and exist from the back to the top of the eyeball

Levator aponeurosis
A thin membranous tissue that connects the levator palpebra muscle and the tarsal plate, which protects the eyeball, and the levator tendon membrane pulls the tarsal plate in conjunction with the contraction of the levator palpebra muscle to open the eyelids.

Muller muscle <br /> A muscle that exists behind the levator aponeurosis, which connects the levator palpebra muscle and the tarsal plate in the same way as the levator aponeurosis, and the levator aponeurosis lifts the tarsal plate by contracting. Has a role to assist work

Tarsus (Kenban)
A plate-like tissue with dense collagen fibers on the edges of the upper and lower eyelids that protects the eyeball and is pulled up by the contraction of the levator palpebra and Müller muscles.

Sauce eye plasty (glamorous line formation / lower eyelid control)

After making an incision on the back of the lower eyelid, surgery to suture and shrink the conjunctiva and muscles that pull the lower eyelid is called sagging eye plasty . Since it is possible to lower the line of the lower eyelid half from the outer corner of the eye by sagging eye plasty, it is possible to lead to the eyes with an impression that tends to sag, and depending on the medical institution, "glamourous line formation" or "glamorous line formation" It is also called "lower eyelid control".

In addition to the width of the eyes on the outer corner of the eye widened by the incision on the outer corner of the eye, the area where the white of the eye is exposed is further widened by lowering the line of the lower eyelid half from the outer corner of the eye by the sagging eye plasty, so the effect of making the eye look larger Will be felt . In addition, it is possible to suppress the relapse after surgery for the outer corner of the eye by simultaneously forming the sagging eyes.

Main techniques of sagging eye plasty
  • A method of excising the skin by making an incision from the skin surface of the lower eyelid
  • A method of excising the skin by making an incision from the back side of the lower eyelid (conjunctival / mucosal side)
  • A method in which an incision is made from the back side of the lower eyelid (conjunctival / mucosal side) and the skin is not excised.
  • How to sew the conjunctiva and muscles of the lower eyelid with thread

Incision in the inner corner of the eye

An incision is an operation to expose the pink lacrimal caruncle (mucous membrane) in the inner corner of the eye by incising or removing the thin skin Mongolian folds that cover the white of the inner corner of the eye . It is said that the presence or absence of Mongolian folds, which tends to be common in the eyes of Asians, is determined by heredity, and by eliminating these Mongolian folds, the width of the eyes on the inner corner of the eye can be seen wider, which is impressive. It is possible to aim for big eyes .

In addition, since the distance between the eyes is narrowed, it can be expected to improve the distance between the eyes, and it can also be expected to have the effect of making the nose line visible. By performing the incision at the same time as the outer corner of the eye, the exposure of the white of the eye can be expanded on each of the outer and inner corners of the eye, and the width of the eye can be further widened .

Main surgical procedures for incision of the inner corner of the eye
  • Crescent method
  • Z-shaped formation
  • W-shaped formation

Double plastic surgery (double plastic surgery)

Double plastic surgery (double plastic surgery) is an operation that artificially forms the structure of the eyelid where the double eyelid line appears, and is one of the cosmetic surgery performed in many medical institutions. Not limited to single eyelids, double eyelids may undergo surgery to get closer to the ideal double line, such as "parallel type double" or "suehiro type double". By performing it at the same time as the incision in the outer corner of the eye, it is possible to aim for an ideal finish such as widening the width of the eye while making an impressive double eyelid .

Main techniques of double plasty
  • Implantation method to form double lines with thread without incising the skin of the eyelids
  • An incision method in which the eyelids are incised to form a double line
