1, autologous fat filling by injection
The principle is that fat particles are evenly dispersed in the recipient tissue, and fat is injected at multiple points during injection, and the injection level should be subcutaneous and retromammary space (during breast augmentation). The injection amount of each acupoint should not exceed 1ml to avoid a large amount of fat concentrated in a certain part, and it should be smoothed after injection. This method is small in size and scattered in parts, which is easy to establish the blood supply of the implant and is beneficial to the survival of fat particles.
2. Selection of autologous fat donor site
Because of the difference of lipoprotein lipase activity in different parts of human body, the activity of high lipoprotein lipase is beneficial to the regeneration and survival of transplanted fat cells. According to the research, the activity of lipoprotein lipase in thighs and buttocks is the highest, which is beneficial to the regeneration and survival of transplanted fat cells, followed by lower abdomen and upper abdomen. According to the study of human body fat and the distribution of deep fat in these parts, the lower part of trunk is generally chosen as the first choice of autologous fat material.
3, the method of liposuction
The method of sucking adipose tissue during operation will directly affect the result of operation. In the process of liposuction, it is inevitable that some cells will be damaged, and the degree of damage is great. The fewer living cells, the lower the survival rate. Researchers advocate the use of empty needle liposuction, and its negative pressure does not exceed 0.05MPa, which can effectively reduce the damage to cells. If other non-invasive techniques are used to suck fat, the straw should be a thin tube below 4 mm
4. Purification of autologous fat
Fat particles extracted from patients should be washed and filtered with 4-degree normal saline to wash away the damaged fat cells, fat drops and blood. Special attention should be paid to aseptic operation in the purification process, so as to reduce the storage time of fat particles in vitro as much as possible and improve the survival rate of fat cells. These needs require doctors to have a high degree of responsibility and patience, handle fat particles carefully and improve the success rate of surgery.
At present, the lower part of human trunk is generally selected as the donor site for autologous fat filling, and the technology of fat absorption and treatment is becoming more and more mature, which greatly improves the success rate of surgery and has obvious postoperative effect, so there is no need to worry about the low survival rate of autologous fat after surgery. However, beauty lovers still need to pay attention to the fact that autologous fat filling surgery requires high skills of doctors, and it is necessary to choose a professional and experienced doctor for surgery in order to achieve the ideal cosmetic effect.
How to improve the survival rate of fat cells after fat filling
For the choice of injection filler filled with autologous fat, experts suggest that autologous fat is the best. Because, whether it is filling injection of hyaluronic acid or microcrystalline porcelain, its disadvantage is that it needs repeated filling injection, which is not only troublesome, but also expensive. Autologous fat can not only achieve the filling effect, but also make the skin better. As long as it can increase the survival rate of fat, it can achieve almost permanent results. We all know that autologous fat filling is safe, and there is almost no rejection reaction in the body, but the effect will be good without fat filling, because the survival rate of fat is not high, so how to improve the survival rate of fat filling has become the primary task. At present, the most effective way to increase autologous fat filling is to strengthen As layer by oral nano-collagen, so as to achieve the effect of tightening and improving the face and improve the fat survival rate.
New muscle silver beauty experts introduced that there are four aspects to improve the survival rate of autologous fat:
(1) In order to improve the survival rate of fat, we must pay attention to the method of aspiration, and the method of aspiration of fat tissue during operation directly affects the result of operation. Surgery will inevitably cause some cell damage and destruction. The greater the degree of injury, the fewer living cells and the lower the survival rate. Most scholars advocate empty needle liposuction, and its negative pressure is less than 0.05MPa, which can reduce the damage to cells. If other non-invasive techniques are used to suck fat, it is best to use a thin tube below 4mm as a straw. Because the whole operation was carried out in the subcutaneous fat layer without big blood vessels and nerves, all the fat was extracted, and the patient basically had no bleeding and pain.
(2) Selection of donor site for autologous fat breast enhancement, and thigh as far as possible, with high fat activity. It was found that LPL activity of lipodynamic lipase in different parts of human body was different. It was found that the lipoprotein lipase activity in thigh adipose tissue was higher than that in other parts. LPL activity is high, which is beneficial to the regeneration and survival of transplanted adipocytes. The LPL activity of thighs and buttocks is the highest, followed by lower abdomen and upper abdomen. According to this study and the deep fat distribution in these parts, the lower part of trunk should be the first choice for autologous fat breast augmentation fat transplantation.
(3) the method of injection. Its principle is to evenly disperse fat in the recipient tissue and inject it at multiple points. The injection level should be subcutaneous and retromammary space. The injection amount of each acupoint should not exceed 1ml to avoid a large amount of fat concentrated in a certain part, and it should be smoothed after injection. This method is small in size and scattered in parts, which is easy to establish the blood supply of the implant and is beneficial to the survival of fat particles.
(4) Purifying fat particles to extract high-quality fat. The collected fat particles should be washed and filtered with 4-degree normal saline to wash away the damaged fat cells, fat drops and blood. Special attention should be paid to aseptic operation during purification; The storage time of fat particles in vitro should also be reduced as much as possible to improve the survival rate of fat cells. Finally, nursing care after breast augmentation with autologous fat transplantation is also very important. Don't squeeze for seven days after injection, because it hasn't been shaped yet, and it will be deformed if it is squeezed too much. Don't stay up late to smoke for a short time after operation, and add more nano-collagen and vitamin C; After menopause, women can take more female hormones.
Precautions before autologous fat filling:
1, cardiovascular and cerebrovascular diseases, the doctor should be informed of the medical history so that the doctor can confirm the operation plan.
2, do the corresponding physical examination to ensure that the body has no inflammation and no infectious diseases.
3, 30-90 days before surgery, take cell repair nutrition new muscle drink, once in the morning, one bag each time (13g), to improve the fat survival rate.
4. Do not take drugs containing aspirin within 2 weeks before operation, so as not to affect the coagulation function of platelets.
5. Women during menstruation and pregnancy should avoid this special period before surgery.
6. Keep your body and face clean and sanitary, and don't put on makeup before the operation (it is deceptive to fill with autologous fat).
What should I pay attention to after autologous fat filling:
1, once in the morning and once in the evening,13g cells, to repair and nourish the new muscle silver nano-collagen for 3 ~ 6 months. Ordinary collagen failed, not to say that nano-collagen failed to achieve the repair effect.
2, as appropriate, the local wound pressure dressing or ice pack cold compress, to help reduce swelling and pain.
3. Don't press the wound when sleeping, causing swelling.
5. Spicy food should be avoided.
5, strictly abide by the doctor's advice and follow-up.
6. Avoid water in the surgical site within one week after the operation and keep the wound clean and dry.
