Clinical manifestations and causes of double eyelid surgery's failure 1, incision scar. The reasons are incision infection, irregular incision edge, poor alignment, or patients with scar constitution. 2, the double eyelids are too wide, too narrow, too long, too short, and bilateral asymmetry. The reason is improper design, the design line is too wide, too narrow, too long and too short, and the two sides are asymmetrical, and the design line is not cut when cutting; The bilateral asymmetry of the patient itself is not considered in the design. 3. The formation of triple eyelids. The reason is that the original double eyelid adhesion line is not separated, and the original double eyelid line and the newly designed double eyelid line form a triple eyelid, which is more common in the catgut embedding method; Excessive excision of orbicularis oculi muscle above the incision leads to the adhesion of upper eyelid skin and deep tissue to form a triple eyelid. 4. The appearance is not beautiful. The patient's eyes are short, forming wide double eyelids and round eyes; The lower edge of the incision is not enough, and the double eyelids are bloated and unnatural; The appearance of double eyelids is not in harmony with the five senses. 5. Blinking is weak. Before operation, the patient had mild ptosis or weak upper eyelid muscle strength; Injury of levator palpebrae aponeurosis caused by too deep incision during operation; Early scar hyperplasia and contracture can cause. 6. The double eyelid line disappears. The reason is that the design line of double eyelids is too low to form inner double eyelids; Excision of orbicularis oculi muscle in front of meibomian is not enough to prevent skin from adhering to meibomian; Not fixed to the aponeurosis of tarsal plate during suture; The stitches are taken out too early and the bonding is not strong enough. 7, eyelid depression. Excessive resection of orbital septum fat. If you pay attention to the situation, you can avoid many sequelae: 1, double eyelid surgery is not suitable for women during menstruation and after pregnancy. 2. double eyelid surgery can no longer take steroids or aspirin and other anticoagulants that are not conducive to hemostasis a few days ago. 3. Patients with major organ diseases such as abnormal blood pressure or heart disease should not be operated. 4, if the patient has a history of bleeding, should check the platelet and bleeding coagulation time. 5, patients with conjunctivitis, blepharitis, trachoma and other eye diseases must be cured before they can do double eyelid surgery. Patients with inflammation around the eyes should also be actively treated before operation, and surgery should be performed after the inflammation is completely eliminated. 6. Patients with congenital amblyopia, ptosis, facial paralysis and palpebral insufficiency are not suitable for double eyelid surgery. Chengdu Hengbo Plastic Surgery Hospital has a good effect of Korean blink and seamless double eyelids. After double eyelid surgery, the Korean minimally invasive surgery recovered quickly, with slight swelling in 3-7 days and basically returning to nature in one month. Ice compress 48 hours after operation and raising your head when sleeping within 3-5 days can reduce swelling and speed up recovery.
