Autologous fat survival rate

Many friends think that using their own body fat to fill other parts of the body should have a very high survival rate, but this is not the case. The survival rate of autologous fat is only 50% or 60%. In addition to the different blood supply between the original site and the transplanted site, the doctor's fat suction or the entire liposuction process will also affect the survival rate of fat filling.

How long does it take for autologous fat to fill the face?

After autologous fat facial filling, it usually takes 3 months for the fat to stabilize and survive. This is because fat cells need sufficient blood supply to survive permanently. This process usually takes about 3 months. During this process, some of the fat tissue that does not receive blood supply will be absorbed. For this reason, autologous fat facial filling usually takes 3 months to achieve the final survival effect. Once the cell survival rate after facial filling is determined, the effect of facial fat filling will be stable.

What is the survival rate of autologous fat facial implants?

The survival rate of autologous fat facial filling in general hospitals can reach 30%~50%. If you encounter a doctor with very good skills, the survival rate of autologous fat facial filling can reach 50%~65%. Why is there such a big difference in the survival rate of autologous fat facial filling? This is because fat filling is actually fat transplantation. In addition to the different blood supply between the original site and the transplanted site, which will affect the survival of fat cells, the doctor's liposuction and injection methods and the process of fat purification will also affect the survival rate of autologous fat facial filling.

Determinants of the survival rate of autologous fat transplantation in the face

Body fat mass

The factors that affect the survival rate of autologous fat facial filling include the quality of the fat itself. The quality of each person's fat is different. If the density and viscosity of the fat are just right, the survival rate of the fat will be high; if the fat is mixed with a lot of oil and impurities, the survival rate of the fat will be poor. Generally speaking, for thinner people, there are not many areas where fat can be extracted and the fat purity is not enough. Therefore, the effect of autologous fat filling for apple muscles on thinner people is not as good as that on girls with more fat.

Method of injecting fat cells

When doctors perform autologous fat injections, the best way to inject fat cells is to disperse them evenly in the tissue of the recipient area, and inject the fat at multiple points. The injection layers should be subcutaneous and retromammary space, and the injection volume at each point should not exceed 1 ml. This can ensure the survival rate of autologous fat facial filling and avoid concentrating a large amount of fat in one area, which can easily lead to cell necrosis. This method makes it easier for the implanted fat cells to re-establish blood circulation, which is beneficial to the survival of fat particles.

Liposuction method

Liposuction surgery will inevitably cause damage and destruction to some fat cells. The greater the degree of fat cell damage, the fewer living cells there are and the lower the survival rate. Therefore, the method used by the doctor when sucking fat is particularly important and is also a key factor affecting the survival rate of autologous fat facial filling.

The process of purifying and washing fat

Doctors use 4-degree saline solution to clean and filter the fat particles to wash away damaged fat cells and blood. During the purification process, attention must be paid to aseptic operation, and the storage time of fat particles in vitro should be minimized as much as possible. This is because fat cells are prone to spontaneous apoptosis if not properly stored in vitro. Therefore, ensuring a short in vitro storage time and aseptic operation can improve the survival rate of autologous fat facial filling.

How long does it take to recover from autologous fat grafting?

Trauma after autologous fat removal can cause an inflammatory response. The water content inside and outside the tissue cells increases significantly, which will cause swelling. Therefore, there is a swelling period of 5-7 days after facial fat filling. During the swelling period, the facial fat will be swollen and hard. It takes about 10 days for the fat to soften after filling. The face will return to its natural state in 3 weeks to 1 month. Then it is the absorption period of about 30 days to 80 days, and it will be basically fixed after 3 months. The fat after it survives is the same as the original one, which is "your own meat". The unabsorbed or unlived fat will be excreted from the body through metabolism to achieve perfect results.
