2. Technical principle
Z-plasty is a special skin flap transplantation. The skin at the inner canthus was peeled off by surgical technique to form two triangular flaps. Using the relaxation of skin tissue, the positions of two triangular flaps are exchanged to make the inner canthus point move inward. After suturing and fixing the skin, the epicanthus is removed and the epicanthus is enlarged.
3. Adapt to the crowd and taboo crowd
1) Suitable for people: For those with mild or moderate epicanthus, the medial canthus angle must be widened if the medial canthus spacing is widened and needs to be widened, or if it affects the formation of entropion in double eyelid plastic surgery.
2) Taboo crowd
① Hemorrhagic diseases and patients with hypertension, active and progressive diseases of vital organs such as heart, lung, liver and kidney, uncontrolled diabetes and infectious diseases.
② Congenital amblyopia, strabismus, and acute and chronic infectious diseases with uncontrolled inner eye, outer eye or eye periphery.
③ Paralysis of facial nerve and incomplete closure of palpebral fissure.
④ Exophthalmos or eyelid retraction.
5 women during menstruation or pregnancy.
6 mental disorder or psychological disorder, lack of awareness of their own conditions.
⑦ Family members are firmly opposed.
4. Cost: 3,000-5,000 yuan
5. Technical methods
① Positioning: Draw a Z-shaped longitudinal axis and two corners on the edge of epicanthus.
② Local anesthesia.
③ Cut the skin and peel off two triangular skin flaps under the skin.
④ Cut off part of orbicularis oculi muscle at epicanthus to shorten medial canthus ligament.
⑤ Exchange the positions of the two triangular leaves.
⑥ suture and fix the skin.
⑦ Pressure dressing.
6. Risks and complications
① Scar hyperplasia of epicanthus: Generally, it will soften and flatten itself 3-6 months after operation. If scar hyperplasia is obvious, physical therapy, massage and external use of scar cream can be done according to the doctor's advice.
② Redundant skin correction is not ideal: surgery can be performed 3-6 months after operation.
③ Skin flap necrosis: The skin flap is too thin, the suture tension is too tight, and the dosage of adrenaline is too large, which are the main causes of skin flap necrosis.
④ Infection: In case of infection, you should seek medical advice in time.
7. Course of treatment and recovery time
The stitches were removed 5-7 days after operation. Scar can be softened and flattened 3-6 months after operation.
8. Take notes
1)
① Do not take drugs containing aspirin within two weeks before operation, because aspirin will reduce platelet coagulation function;
② Patients with hypertension and diabetes should inform the doctor of their condition at the initial diagnosis, so that the doctor can confirm the operation plan;
③ Make sure that you are in good health before operation, and there is no infectious disease or other body inflammation;
④ Do not make up before operation;
⑤ Women should avoid menstrual period.
2) Matters needing attention after operation
① Ice compress within 72 hours after operation to prevent postoperative bleeding and obvious swelling, and hot compress after 72 hours to promote blood circulation and reduce swelling; If there is bleeding and severe hematoma after operation, you should go to the hospital for follow-up in time;
(2) Try to avoid water accumulation in the surgical site within 7 days after operation;
(3) Ensure that the surgical site is clean to prevent infection. If there is blood scab or secretion on the wound, it can be wiped with sterile normal saline according to the doctor's advice;
④ Don't watch TV, newspapers, etc. Within 2 weeks after operation, it is best to lie in a semi-lying position when lying in bed to avoid excessive eyelid fatigue or low head position, which will aggravate the swelling of the wound;
5 avoid eating irritating foods such as peppers;
⑥ Take medicine in strict accordance with the doctor's advice and make follow-up visits. 1. label: surgery, first-class surgery.
2. Technical principle
Speath's method is to cut and separate the skin in the inner canthus to form four triangular flaps, and then use the relaxation of skin tissue to cross and exchange the positions of triangular flaps in pairs, so that the inner canthus points move inward, and the canthus is enlarged after suture and fixation.
3. Adapt to the crowd and taboo crowd
1) Adapt to the crowd: those who adapt to severe epicanthus and need to remove epicanthus and open their eyes.
2) Taboo crowd
Refer to "Z forming method"
4. Cost: 3,000-5,000 yuan
5. Technical methods
① Positioning: Design the central axis of epicanthus margin, which is perpendicular to the incision line of 1/3 of the upper and lower eyelid margin, and the incision line with an included angle of 60 between the midpoint of the central axis and the upper and lower sides of the nose to form four triangular flaps.
② Anesthesia: local infiltration anesthesia.
③ According to the designed orientation, the skin and subcutaneous tissue were cut and separated to form four triangular flaps.
(4) Four triangular petals cross each other and exchange positions.
⑤ Suture and fixation, and pressure dressing.
6. Risks and complications

2. Technical principle
Mustard method, also known as Mohs method or four-flap method, refers to re-taking two inner canthus points at the epicanthus of eyelid, and making incision lines at the midpoint of the connecting line of the two inner canthus points in the direction of upper and lower eyelid and nasal side respectively. By separating subcutaneous tissue, four skin flaps were freed, the medial canthus ligament was exposed, and the suture ligament was folded to remove excess skin.
3. Adapt to the crowd and taboo crowd
1) Suitable for people: it is suitable for severe epicanthus, posterior epicanthus, epicanthus widening and ptosis. It is necessary to remove epicanthus and open eyes.

Y-V method is to make a Y-shaped incision in the skin at the corner of the eye, then push the V-shaped flap in front of the Y-shaped flap, and then make a V-shaped suture to shift the inner canthus inward, so as to remove the epicanthus and open the corner of the eye.
3. Adapt to the crowd and taboo crowd
1) Adapt to the crowd: adapt to the beauty seekers who need to increase the length because of the short length of the eye fissure. In addition, congenital microphthalmia, widened orbital distance, congenital epicanthus and acquired trauma, or epicanthus formed by burns and scalds can all be corrected by this method.
