Fat transplantation centrifuge about autologous fat transplantation began in 1893, Illouz proposed the fat granule injection transplantation in 1986, this technology with fat suction technology generally launched more and more extensive application. Outcome of fat transplantation centrifuge about transplantation of fat particles, there were scholars believe after autologous fat transplantation is not survival, all be autologous tissue absorption, or be wrapped with fiber scar like tissue. Study of fat transplantation centrifuge in recent years appear after autologous fat transplantation can partly survival, especially put forward preadipocyte theory can provide more convincing evidence for the survival of fat transplantation. Of course, the ultimate purpose of application of autologous fat grafting filling is fill a depression, improve the appearance, so whether transplantation of adipose can only survival, graft site volume increases situation can be maintained for a long time, have reached the purpose, even after the transplantation of adipose tissue increases is fiber born filling concave deformity, understanding of fat transplantation centrifuge to only smooth surface, is acceptable.
Since the fat graft volume decreased to a certain extent, and our purpose is precisely the transplantation with graft tissue depression, so we are very concerned about the survival of autologous fat transplantation by what factors influence the amount of. Fat transplantation centrifuge common thought after autologous fat transplantation survival quantity by fatty take and disposal way, fat injection amount of fat injection method of operation and the unit area effect. To obtain a fine needle aspiration of fat particles is small, after the injection and the recipient bed contact area, a survival benefit to cell. The fat particles obtained after rinsing and suction can be static to be purified, and high-speed centrifugal will cause damage to fat cells, so do not use. A number of studies have proved that basic fibroblast growth factor can promote the unity and the proliferation of vascular endothelial cells, promote angiogenesis, improve the survival rate after autologous fat transplantation. Fat transplantation centrifuge fat injection selection slightly rough used to suction needle, needle injection before using in the subcutaneous respectively form a lacuna, edge needle side injection, so that the injection resistance landing, transplantation of fat in the affected area distribution, but also to avoid the damage of high pressure on the graft of the fat particles. Nutritional condition of depression part can provide to graft a certain limit, the excess of transplantation of autologous fat transplantation can not guarantee adequate nutrition, so the disease such as severe depression, fat transplantation can consider the transplant centrifuge suggestions to ensure the survival rate is high, otherwise the transplantation of autologous fat can not set up the blood circulation in the local. Will be absorbed or central necrosis form scleroma. The transplantation of adipose quantity is the measure, are also differences in individual parts and the rate of survival of fat transplantation, so postoperative excess or deficiency present transplantation correction is unavoidable, these need to explain clearly to the patient before the operation. The second operation can improve the survival rate of graft, and the more radical measure transplanted amount can also avoid the transplantation excess and overcorrection, so it is more secure.
