The failure of liposuction is manifested as obvious thick and thin asymmetry of both legs, obvious depression above the knee, poor flow line, pit-like after liposuction of the buttocks, poor articulation of liposuction of the waist and abdomen, resulting in obvious stripes or unevenness, which will cause serious impact on the patient’s life if not repaired in time. The main hazards of liposuction failure repair surgery are: 1. Liposuction repair surgery will form trauma on the skin surface again, which has the common risks in traditional surgery, easily triggering wound infection, bleeding, scarring and other problems; 2. As the fat is removed from the local part of the body, there will be vacant parts in the deeper layer of the skin, and the skin will lose support, easily triggering the symptoms of uneven skin, and the body fluid will also flow into the vacant parts. 3, after liposuction surgery, it may also lead to scar growth at the liposuction site and increased pigmentation after recovery; 4, one of the most serious hazards is that after fat extraction, the original fat tightness is broken, and the fat in the body is prone to free state, allowing fat to flow into the blood, which is prone to flow into the lungs together with the blood and cause pulmonary embolism. After liposuction repair, do not eat seafood and spicy food in the near future, carry out light activities in the early postoperative period, do not stay in bed and rest, and carry out daily activities; those with mental or light physical labor can work as usual without rest. No bathing for 3-5 days after surgery to avoid contaminating the wound.
