Liposuction is a method that uses a negative pressure vacuum suction device (0.5-l.0 atmospheric pressure) connected to a metal suction tube with a suction hole at the end to enter the subcutaneous through a small incision in the skin and suck out the local accumulation of fatty tissue to improve the obese body shape. So, what do you need to know before liposuction surgery? The following is an introduction to the issues that need to be understood before liposuction surgery: 1, not the whole body can be liposuction Liposuction surgery belongs to one of the plastic and cosmetic surgery body sculpture surgery, the principle is to suck out the excess fat in a part of the body through the method of negative pressure attraction, in order to achieve the purpose of rapid local slimming body. The common parts of body liposuction are: face, chin, neck, shoulder and back, limbs, abdomen, side waist, buttocks, etc. There are certain parts of the body where liposuction cannot be performed, such as the front and outer calves and forearms. These parts are mainly muscles with little fat. Even if fat suction is done, the result will not be good and it will easily lead to nerve and blood vessel damage. In addition, there are some parts of the human body where liposuction must be done carefully, such as the face and calves. Careless operation or inexperience can easily lead to skin necrosis and unevenness in these areas, leading to lifelong regrets. 2, detailed design before surgery Although the result of fat extraction is to reduce the volume of a certain part of the body and thin the fat layer, it must be coordinated with other parts of the body, not how much you want to suck, where you want to suck. Before the whole body liposuction, the patient should communicate and discuss with the plastic surgeon in detail and design a reasonable surgical plan according to the candidate’s own situation, so as to “have a bottom in mind”. The procedure uses advanced equipment and uses a layer-by-layer scanning method to suck out excess fat in a hierarchical manner, which does not produce unevenness. In addition, more than 80% of the fat that needs to be extracted can be sucked out in one suction, which solves the pain suffered by the candidates due to the long operation time. The post-operative liposuction effect is natural, with smooth lines and perfect curves. 3, liposuction should not be excessive The implementation of fat suction should follow the principle of “a small number of times”. The small number of suction areas will result in less trauma, faster recovery, less pain, and no need for general anesthesia. On the contrary, large area fat suction is very traumatic, painful, slow recovery, and requires a lot of anesthetic drugs, increasing the risk of anesthesia accidents. In addition, large fat aspiration is a very labor-intensive job for the plastic surgeon and can easily lead to fatigue. Even if life safety issues do not arise, fatigue can lead to a decrease in aspiration accuracy, which in turn can affect surgical results. Generally speaking, more than 4 areas should not be aspirated at a time. But all claim to be able to a large number of fat suction, suction parts of unlimited medical institutions, absolutely can not be trusted. 4, choose the regular medical plastic surgery institutions to implement surgery Because of the plastic surgeon’s skills and experience is directly related to the results of liposuction surgery, for example, experienced plastic surgeons in liposuction, will retain a certain layer of fat to ensure the smooth and skin safety after surgery; in order to avoid uneven skin after surgery and damage to neurovascular and other problems, they are very familiar with the anatomical level of the suction site, and as far as possible to do In order to reduce trauma and post-operative bruising and swelling, they will try to operate as gently as possible. The liposuction surgeon should try to find a good doctor with good skills and experience to do the surgery. 5, pay attention to post-operative care Liposuction patients must be clear: liposuction surgery is only a small part of the overall treatment, post-operative care and rehabilitation has an equally very important role in ensuring safety and surgical results. For example, smooth post-operative drainage can speed up the swelling of the surgical area; changing dressings on time can prevent infection; using elastic bandages correctly for 3 months can effectively prevent skin laxity; using infrared physical therapy can promote the softening of the surgical area scar, etc. Liposuction recipients should pay attention to ask about their post-operative care and rehabilitation services when examining whether the plastic surgery institution is formal.
