The main hazards of the buried double eyelid are as follows: 1, the loosening of the line: the most common, if part of the loosening, can make the double eyelid appear unsightly curvature or asymmetry on both sides, if completely loose, there will be double eyelid disappearance, because the position of the buried line fixed in the lid plate is not solid, under blind vision completely rely on the doctor’s hand to determine whether to hang to the lid plate, but can not decide whether it is solid; 2, postoperative hematoma: if If there is no obvious active bleeding, it can subside on its own. If you want to speed up the subside of the hematoma, you can apply ice packs within 48 hours and hot packs after 48 hours; 3. Line allergy and rejection: If there is an inflammatory reaction of rejection, the line must be removed, but because the line is very thin and non-absorbable, if you want to remove it, you have to make a full cut. There are many tissues, such as the lid plate and dermis, and there are many knots between the line and the thread, which are difficult to remove completely; 4. Line rejection outgrowth: the doctor is not experienced enough to wear the skin dermis too shallowly in addition to the lid plate, there will be late line rejection outgrowth, forming a granuloma of the thread knot, in this case, the line must be removed; 5. Active bleeding: if it is a local hematoma, it can be allowed to absorb on its own, while the local activity bleeding, which cannot be stopped by applying pressure or ice, must be promptly treated by a doctor.
