The main difference between them is the addition of stem cells. Autologous fat transplantation of stem cells is generally a composite filling of adipose stem cells and autologous fat. Stem cells are differentiated cells based on fat, which can improve the living environment of fat and transform themselves into fat cells. Since autologous fat transplantation has an absorption process, it remains to be seen whether the operation can be successful at one time.
Whether it is academic discussion or clinical observation, the postoperative fat absorption rate is usually 40%, 50% or even as high as 60%. This is objective, so patients don't have to worry about the survival of fat. Autologous fat transplantation needs two or even three operations to achieve the ideal effect. At present, there are also some attempts, for example, in the process of liposuction separation, by performing some small technical operations or even adding so-called autologous adipose stem cells or adding some other substances to improve the survival rate of fat. This is the main problem in clinical research at present. Therefore, clinically, there is no need to worry about fat absorption, and it is necessary to accumulate the number of operations to achieve the desired results.
Uncontrollable survival rate leads to fat calcification, fat liquefaction and fat necrosis. In Japan, South Korea and other medical countries in the United States, there will be professional repair procedures after surgery. For fat filling, there are mainly the following methods to improve the survival rate of fat filling.
Equipment: Low negative pressure and fine liposuction have less damage to fat cells and are beneficial to fat survival.
Hospital: Choosing the appropriate number of centrifugal revolutions can not only concentrate fat but also not destroy too many fat cells, thus improving the surgical effect.
Doctor: The choice of fat injection level. Face filling needs high injection, and multi-level and multi-point stereoscopic injection can make better use of fat cells to survive.
Personal aspects of the theme:
First: there will be pain in the first three days after operation. You can apply erythromycin ointment instead of washing your face. Don't take a bath. No ice or hot compress. Postoperative infusion or prophylactic application of antibiotics for 3 days, light pressure dressing for 5-7 days to prevent inflammatory infection; In case of infection, you need to seek medical attention in time.
Second, timely supplement the special nutrient for cell survival, namely, fat reactivation factor -BFGF, as a cell reactivation factor conducive to fat survival, fundamentally improve the physiological environment of blood circulation, protect the invariance and inactivation of protein molecules, provide necessary nutrition for new fat and adipose tissue in the recipient area, and improve the activity of fat cells. Vitamin E supplement, light diet, fat period of 6 months.
Third, one week to one month after operation, avoid massage and ultrasonic scalpel treatment on the local filling part, so as not to cause thermal damage and affect the survival of fat cells.
