In fact, the post-operative effect and the doctor’s filling technology have a direct relationship, the doctor filling is very important, filling to where, filling how much, whether the tissue gap pressure is appropriate, these will affect the retention of fat, on the other hand is the post-operative care, less post-operative exercise for the chest, pay attention to nutrition, these to get twice the result with half the effort. The absorption rate is mainly influenced by three aspects: 1. firstly, it depends on the technical experience of the doctor; 2. secondly, it depends on the quality of the fat. The fat particles in the thighs and buttocks are smaller and denser, and their lipoprotein activity is higher, so the survival rate after transplantation is higher; the fat quality in the abdomen is poorer, and the survival rate after transplantation is lower; 3. the amount of each injection. The larger the amount of each injection, the lower the survival rate. The tissue capacity of the breast is limited, so too much fat tissue cannot be injected at one time, otherwise the transplanted fat tissue cannot get sufficient blood supply and is prone to necrosis.
