What is fat gum?
Adipose stem cell gel (SVF GEL) is an injectable gel-like fat transplantation material, which is rich in adipose stem cells and extracellular matrix (mainly composed of collagen, elastin and mucopolysaccharide) after oil droplets in adipose tissue are effectively removed by physical methods.
Defects of autologous fat filling
1, the survival rate of adipocytes varies with individual constitution?
The survival rate of fat particle transplantation is relatively low. Generally, the survival rate of forehead fat filled with autologous fat is between 30% and 70%, which means that all injected fat will not survive. In addition to requiring doctors to be skilled, the quality of fat cells also varies with individual fat quality. Overweight people, too much abdominal fat, too much fat impurities, and too thin people have low purity of fat cells, all of which are factors that cause low survival rate of fat cells. ?
2. Injecting too much fat causes edema?
When filling the forehead with autologous fat, if the doctor does not grasp the amount of fat filling and injects too much fat into the forehead, it will easily swell the forehead of the subject and affect the appearance. ?
3. Will injecting too little fat affect the effect?
Some patients can't see the effect after autologous fat filling, which is also related to improper control of fat injection. If the extracted body fat is not preserved properly in vitro, it is easy to die, and the transplanted area will be difficult to survive due to ischemia, so the survival rate of fat cells is relatively low. If too few fat cells are injected into the forehead, it will easily lead to ineffective autologous fat filling.
How to improve the survival rate of autologous fat
After autologous fat filling, the instability of autologous fat at the filling site may lead to the non-permanence of autologous fat filling, which requires secondary autologous fat filling to achieve the effect. When autologous fat is filled, adding PRP (that is, autologous serum) can improve the fat survival rate of the first autologous fat filling to 20%~30%. Need to be reminded that adding PRP must be carried out in strict accordance with national standards, and sister paper should choose to go to a regular plastic surgery hospital when injecting.
How to fill induration with autologous fat?
Don't deal with the small knot?
After autologous fat filling, if the induration is only the size of a nail, patients need not worry too much. Generally, this kind of small induration is the result of necrosis of fat cells after autologous fat filling, and it will be absorbed by the body after a period of time without special treatment. ?
Should the induration be dissolved and taken out if it is serious?
If the induration appears after autologous fat filling and has not been eliminated after a period of time, then you need to see a doctor to solve it. Ask the doctor to dissolve the autologous fat and take it out with a special needle. This induration is generally formed after breast augmentation with autologous fat filling. Due to the limited blood supply to the chest, the fat survival rate is about 50%, and only about 200 ml of fat can be injected into both sides of the chest at a time. If the injection is excessive, it is easy to cause ischemic necrosis and induration.
