When we talk about fat everyone thinks of flab on the body. That’s right, fat grows in the wrong place, like elephant legs, swimming circles, butterfly sleeves, affecting the aesthetic appearance and making people worry. However, for “autologous fat filling”, fat is soft gold, a good way to “turn fat into treasure”. It can be used for forehead augmentation, temple augmentation, lip augmentation, chin augmentation, apple muscle augmentation, total fat filling, tear trough augmentation, etc. How does autologous fat turn fat into treasure? This starts with the principle of autologous fat filling. Autologous fat filling is to suck suitable fat cells from specific parts of oneself, such as fat from the abdomen, buttocks, thighs or upper arms, etc. Using low temperature and low pressure centrifugal technology, it is separated, purified and purified to get pure fat particles, which are then injected and transplanted to the parts that need to be filled, so as to make the face young, rounded and full. The advantages of autologous fat filling are still obvious. From the principle of this technology, it is not difficult to see that it uses the candidate’s own fat, the body will not be rejected, safe and reliable, easy to survive. Coupled with the use of free fat particles injection, transplantation trauma is small, the donor and recipient areas do not leave obvious scars, the recipient area of the form of uniformity and naturalness, no body surface shadow. Repeatable injection, easy to shape. Autologous fat filling is so safe, will there be any complications? Any surgery will have certain risks, and autologous fat transplantation is no exception. After successful injection of fat grafting, the common complications are as follows: 1, fat liquefaction, calcification: the injection volume is large or not enough to disperse, part of the fat does not survive, there will be a small amount of liquefaction, or the local appearance of small lumps of nodules accompanied by redness and swelling; 2, local fat necrosis: a larger amount of transplantation in the unit of space, the tissues did not all survive, the center part of the fat will be necrotic, and the center part of the fat will be necrotic. Part of the fat in the center will be necrotic, and in serious cases, even local nodules and aseptic inflammation will appear. 3, fat embolism: this is the most serious and rare complication in the process of autologous fat transplantation. It can lead to serious complications such as blindness localized cerebral infarction or even vegetative. Although there are complications of fat filling, the physician’s rich clinical experience and formal operation can avoid and minimize the risk as much as possible.
