Abdominoplasty removes excess skin and skin folds from the abdomen and improves the external shape of the patient by removing abdominal wall fat and associated skin for the purpose of abdominal contouring. The risks of abdominoplasty are as follows: 1. Hematoma: It is one of the most frequent complications, mostly due to poor postoperative dressing or poor drainage, and can also be caused by improper intraoperative operations, etc. The subcutaneous petechiae and small hematomas caused by a small amount of bleeding can generally be left to fade naturally without special treatment. For large hematomas that develop rapidly, incision should be made to stop the bleeding; 2. Skin necrosis: mostly caused by improper flap separation. For small area of skin necrosis, the necrotic tissue should be removed and the wound surface should be directly pulled together and sutured or local flap transfer should be used. For large area of skin necrosis, skin implant repair is required; 3, incision infection, fistula: related to the aseptic operation and postoperative care. Once incisional infection and fistula occur, the local infected area and fistula should be removed and the traumatic infection can be healed together; 4. Bilateral asymmetry: inconsistent with the amount of skin and fat removed on both sides, or inconsistent with the degree of muscle fascia tightening. For obvious asymmetry, it can be corrected by another surgery after 3-4 months; 5, sensory loss or abnormalities: during surgery, it may cause nerve damage due to improper operation, mostly persistent, only in cases of skin removal, especially in the distal end of the abdominoplasty flap and around the newly established umbilicus; 6, after surgery, it may lead to scar growth and formation of hyperpigmentation during the recovery process.
