Autologous fat grafting is now widely available and has shown considerable results especially in filling larger volumes of soft tissue in the face. Moreover, autologous fat is also more histocompatible and economical than allogeneic materials, so fat is still the most desirable filler material known. His disadvantage is the uncertain absorption rate, which is statistically analyzed at about 50-70%. That is, more than half. Of course this is under normal injection and the fat cannot be contaminated, otherwise it will be completely necrotic and may even cause more serious infections. So if you choose to do fat grafting filler may need to be prepared for the following: 1, surgery to achieve more satisfactory results may need to be carried out 2-3 times, different parts may be more different, such as more activity around the mouth will be significantly worse than the temporal. 2, do not ask the doctor to inject too much for you at once, too much fat injection can not survive, can not survive once the fat can not be absorbed in time will also cause nodules 3, this kind of surgery in aseptic conditions can guarantee the conditions, the general chance of infection is not large, but still need to be careful. Because once it happens, the consequences are still relatively serious. 4, Finally, the rare complications of this type of surgery is still very serious, or please go to a large, regular medical institutions to do these operations, at least we will be awe-inspiring, careful, every step do not dare to take this surgery lightly.
