Double eyelid repair usually requires reoperation, that is, to cut open the original double eyelids for surgical repair, which needs to be judged according to the specific situation after double eyelid surgery. Double eyelid repair is mainly categorized into the following situations: First, double eyelid asymmetry: if one side of the double eyelid is too narrow or too wide, the wider side can be surgically cut open, the skin along the edge of the eyelid can be removed and then re-sutured, so that it can be kept at the same width as the opposite side. Sunken upper eyelid: In case of sunken upper eyelid, the original incision line can be cut to release the fat from the lateral orbital septum and fill in the sunken upper eyelid, or cut the free small fat block or free granular fat for transplantation, so as to achieve the effect of the correction of sunken upper eyelid. Widening of the incision scar: If the scar at the incision is too wide, the scar at the incision line can be excised and finely sutured, and then anti-scar medication can be applied after surgery to minimize scarring at the wound. Multi-layer blepharoplasty folds: 1. Excessive local skin: the excess skin can be removed to achieve the purpose of correction; 2. Adhesion of subcutaneous tissues: the adherent tissues can be separated through surgical incision and the surrounding tissues can be filled into the adherent place, which can also be used to achieve the effect of repairing the double eyelid; 3. Medically originated ptosis: it is possible to reopen the incision wound and carry out fine separation, to locate the severed end of the levator muscle, to be finely sutured, so as to recover the effect of double eyelids. The wound can be reopened for fine separation to find the severed end of the levator muscle, which can be finely sutured to restore the integrity of the levator muscle and achieve the same effect as that of the opposite side of the eyelid.
