Autologous fat filling has become a popular medical aesthetic program in recent years. Originally look annoying fat, in the development of plastic surgery technology, suddenly become “waste into treasure” spokesman. However, the autologous fat is not the more you use the better, to improve the survival rate of transplanted fat is very important. So why can’t you just fill in as much as you want? First of all, if you are doing facial fillers such as: temple augmentation, forehead augmentation, cheek augmentation, apple muscle augmentation and so on. Although the amount of fat needed is not much, and generally people will have enough fat for filling, sometimes a second surgery is still needed, this is because there will be a certain amount of absorption after the fat filling, and the absorption will be different for different people and different parts of the body. Doctors generally according to the basic situation and their own experience to determine the amount of fat filler, after surgery, if the absorption of the degree of fullness just suitable, naturally all is well, if the absorption of more, a small amount of lack of the second supplement can be, even if not supplemented than will be much more beautiful than the original. If overfilling, absorption is still full of excessive, will make the face look bloated, give a person a kind of “inflatable false face” feeling, will seriously affect the facial aesthetics, belong to the failure of the operation. Secondly, if you need a large amount of fat to fill in the breasts and other parts of the body, it seems that the more fat you fill in, the better, so is it possible to fill in as much fat as possible at one time? Of course not. Autologous fat transplantation to ensure the activity of fat cells is the key to fat survival, and to ensure the activity of fat cells in addition to liposuction to reduce the damage to the fat cells, fat cells injected into the reconstruction of the blood supply is the key to survival, timely access to the blood supply of the fat cells to be able to survive. If too much fat is injected at one time or the injection is too concentrated, resulting in a large amount of fat accumulating together, it will lead to fat necrosis, melting and sucking up due to insufficient blood supply, which will easily lead to infection, fibrosis or calcification and fat necrosis. In addition, the limited volume of the breast itself will also affect the amount of fat injected, so even breast augmentation is not a time to fill as much as you want to fill as much as you want. Finally, we remind you that in order to ensure the postoperative effect, you must choose a regular qualified medical institution with fat transplantation expertise and a professional doctor for overall improvement in order to achieve satisfactory results.
