The length of time to avoid the mouth to cut double eyelids, mainly by the way the surgery is decided, at present can double eyelids can be mainly three methods: the first, the full cut method, that is, the most damage, the longest recovery time, but the double eyelid maintenance time effect is the longest, this approach to avoid the mouth for at least a month or more. Because this method is to remove a part of the upper eyelid skin, the upper eyelid and lid suture, the damage is relatively the largest, avoid mouth can reduce the blood circulation around the eyes, prohibit spicy and stimulating food, reduce scar growth. The second, hemisection method, also called the Korean three-dot method, involves cutting three incisions about 2mm long on the upper eyelid, removing some of the fat, and finally suturing the upper eyelid to the lid, this method has moderate damage and contraindication for about three weeks. The third method, the buried wire method, uses an absorbable protein thread to suture the upper eyelid to the lid directly, which causes the least damage and the shortest recovery time, and therefore the shortest mouth avoidance time, at about two weeks.
