Liposuction, commonly known as liposuction, is a procedure that improves the appearance of the body by removing subcutaneous fat from the body through a special needle. Liposuction removes subcutaneous fat tissue from the body in an attempt to achieve a modern, attractive body shape. Almost all subcutaneous fat can be removed by the surgeon’s suction tube. The subcutaneous fat layer is located between the skin and the deep fascia, which is attached to a deep structure by many fibrous intervals. These fibrous intervals are like numerous cords that pull the skin tightly to the surface of the body, and what is called subcutaneous fat is a myriad of fat globules caught in the fibrous intervals. The task of liposuction is to extract the fat globules with as little damage as possible to the fibrous septa, because the blood vessels, nerves and lymphatic vessels that go to the skin travel within the fibrous septa. The surgeon does the inner sculpting with a rigid metal tube, and the operator must have the following three conditions: ① knowledge of anatomy; ② understanding of human proportions; and ③ dexterity of hands. Liposuction is performed under blind vision, and practice allows for the proper and correct technique of hand position and direction of motion. The surgery is usually done under local swelling anesthesia and you can go home afterwards, but for people who are particularly nervous or sensitive to pain, intravenous general anesthesia can also be used to complete the surgery in a painless manner. There is a period of post-operative swelling at the surgical site, which usually recovers in 1-2 months, with some numbness that takes about 3 months to recover. In order to make the skin retract better, it is better to use elastic clothing for 2-3 months.
