Autologous fat breast augmentation is a kind of breast augmentation surgery, which transplants fat particles from fat parts such as waist, abdomen, buttocks and legs to the chest. Excess fat of breast augmentation patients is sucked out by fine needle, activated and treated into pure fat particles, which are evenly injected into breast augmentation area through microtubule needle to make them survive. No surgery, no bleeding, the breast enhancement effect is real and natural, and the effect of losing weight and shaping is achieved at the same time.
Breast augmentation is the most common cosmetic surgery in plastic surgery. Since its birth, filling materials have become the focus. After the common knowledge of paraffin, silicone oil and other materials, silica gel and physiological saline have been gradually accepted by everyone, but the related complications (including contracture, deformation, hardening, leakage and unnatural feel) still plague doctors and doctors. Therefore, when people realized that autologous fat might become a material for breast augmentation, it was immediately welcomed by doctors and surgeons and was given great expectations. The fat part is getting fatter and the thin part is getting thinner, turning waste into treasure, and reasonably "blending" adipose tissue. This is a nearly perfect treatment concept, which undoubtedly becomes the pursuit and development trend of plastic surgery.
Autologous fat granule transplantation has been used to treat tissue defects and dysplasia for a long time. It was first seen in Neuber( 1893) and Lexer( 19 10). The research in 1950 found that the volume and weight of transplanted fat particles decreased by more than 50%, and the necrotic fat. Coupled with liquefaction, necrosis and infection during treatment, doctors are afraid to ask. Especially in the 1960s, with the appearance of silicone prosthesis, the research of autologous fat particle transplantation basically stopped. The appearance of liposuction technology in 1980s not only made it possible to obtain a large amount of autologous fat, but also made it very convenient and quick. Scholars began to re-study this tissue filling material, which is easy to obtain, abundant in supply and good in tissue compatibility. Carpaneda( 1994) and Guerrerosantos( 1996) confirmed through experiments that the transplanted autologous fat particles can survive under the condition of abundant blood supply. Although there are still some controversies in the specific pathological process, they basically deny the view that transplanted fat particles cannot survive. Eppley and ayhan(200 1) further developed their common sense and found active factors and drugs to promote the survival of fat particles through animal experiments. At this point, autologous fat particles were transplanted. It has also become a common method for plastic surgeons to treat related deformities and defects. Especially for the treatment of facial and systemic soft tissue depression, hemifacial atrophy, etc., it has achieved very good results and has gradually become the first choice.
There are many successful reports about the treatment of breast augmentation (Coleman 1995, Eppley 1992, Bircoll 1987, Qi Keming 2002) and some unsatisfactory reports (Arsek199/Kloc-). But on the whole, the method of drying (1999) has been gradually recognized by people, become the mainstream method, and has been widely practiced. Its technical core lies in preserving fat particles in the process of in vitro treatment in nutrient solution, and screening relatively complete fat particles by centrifugation and multi-level and multi-tunnel injection transplantation. As for the injection amount, it is suggested that the injection amount is 60~80ml at a time (Qi Keming et al. ) and160 ~180ml (chaichir1989). However, through literature review, we must be clear that autologous fat particle transplantation has achieved many good results after nearly 20 years of practice and application, and has become a very popular method. However, the factors affecting the growth of fat particles and the fate of transplanted fat in the body are still unclear. On the one hand, doctors are deeply encouraged by the successful application of autologous fat granule transplantation, on the other hand, they are not sure about the survival rate and long-term curative effect, especially some complications, such as fibrocystic degeneration and its influence on the diagnosis of breast masses, which makes some countries and regions request to suspend the breast augmentation treatment with autologous fat granule transplantation. In this regard, it can be said that it is a critical period for us to give up or continue to develop this treatment.
