How long can fat grafting last

Fat filling is to take out a part of your own fat and put it in some underdeveloped areas or areas where the skin needs filling. This is a surgery, but this surgery does not require surgery or skin incision. It can be completed with just a needle. However, everyone should know that there is no normal medical theory about how long autologous fat can last. For some people, it can last longer if they take good care of it, while for others, it can last shorter.

Adapt to the crowd

1. People with congenital or acquired soft tissue dysplasia.

2. A part of the body that is asymmetrical in circumference and volume.

3. Those whose body needs to be injected with local depression caused by non-fibrous contraction factors at the transplant site.

1. Autologous fat transplantation for the temporal region: During injection, the needle is inserted 1-1.5 cm behind the hairline. There will only be a small needle hole after the operation. Avoid washing your hair or massaging vigorously within one week.

2. Autologous fat transplantation for cheek filling: The injection point can be selected in a hidden place. There will be slight local swelling after injection. Take antibiotics orally for 5 days after the operation. After one week, gently massage the face with your palm.

3. Chin autologous fat transplantation: Chin autologous fat transplantation is also called chin augmentation or chin augmentation. Choose the intraoral mucosa or the outer side of the chin to insert the needle. Take oral antibiotics after autologous fat injection and do not massage within two weeks.

4. Autologous fat breast augmentation: Absorb fat from other parts of the body, process it specially, and inject it into the breasts. After the initial plasma nutrition period, the fat cells implanted in the breast are revascularized under the action of biological factors in the body and the blood supply connection with the surrounding tissues is reestablished to achieve the goal of complete survival. During this process, some inactivated fat cells will be engulfed and absorbed by the surrounding tissues.

Keys to Success

1. Selection of autologous fat donor area

Since the activity of lipase in adipose tissue of different parts of the human body varies, high lipase activity is beneficial to the regeneration and survival of transplanted fat cells. According to research, the activity of lipase is highest in the thighs and buttocks, which is conducive to the regeneration and survival of transplanted fat cells, and decreases in order from the lower abdomen to the upper abdomen. Based on the research on human body fat and the distribution of deep fat in these areas, the lower half of the trunk is generally selected as the preferred donor area for autologous fat breast augmentation.

Second, the method of fat suction injection

When performing autologous fat injection for breast augmentation, the survival rate of the fat directly affects the outcome of the operation. It is inevitable that some cells will be damaged during surgery. The greater the degree of damage, the fewer living cells there are and the lower the survival rate. When injecting fat, the principle is to disperse it evenly in the recipient area tissue, and inject the fat at multiple points. The injection level should be subcutaneous and retromammary space. The injection volume at each point should not exceed 1 ml. Avoid concentrating a large amount of fat in one area. Massage to smooth out the area after injection.

3. Equipment for fat suction

There are many devices for liposuction, and the breast augmentation effect of fat extracted by different devices and injected into the chest is different. Breast augmentation experts advocate the use of empty needle liposuction with a negative pressure not exceeding 0.05MPa, which can reduce cell damage. In addition, it is best to use thin straws that are less than 4mm in diameter.

4. Purification of fat particles

The extracted fat needs to be processed, and the collected fat particles should be cleaned and filtered with 4-degree saline to wash away the damaged fat cells, fat droplets and blood. During the purification process, special attention should be paid to aseptic operation, and the storage time of fat particles in vitro should be minimized to increase the survival rate of fat cells. This requires doctors to have a high sense of responsibility and patience, and to carefully handle the fat particles to improve the success rate of the operation.
