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.
Second, the time of double eyelid repair surgery: within one week or half a year after double eyelid surgery.
Three, cut double eyelid repair operation principle:
1, carefully analyze the reasons for the failure of the previous operation.
2. Redesign the incision line of double eyelids and try to remove all scars from the original incision.
3. Remove the scar in front of the meibomian and fully separate the adhesion between the muscle and aponeurosis in front of the meibomian.
4. When sewing, the arc is smooth and natural, and the aponeurosis in front of the tarsal plate is firmly fixed.
5. When the orbital septum fat is excessively removed in the early stage of surgery, the medial fat can be released, or the lower eyelid orbital septum fat can be transplanted freely, or autologous fat can be injected in several times.
6. Be careful about the tissue during the operation, be gentle and minimally invasive, shorten the recovery period and reduce scar hyperplasia.
