With the development of technology autologous fat transplantation method of breast augmentation began to enter people’s attention, autologous fat transplantation greatly improved the disadvantages and defects of implant transplantation, so that breast augmentation has more options. However, it cannot be ignored that autologous fat transplantation still has certain defects, the fat implanted in the breast is easily absorbed by the body, the breast enlargement effect is not good, and multiple transplants are needed. BRAVA+ autologous fat transplantation technology has opened a new era of breast enlargement. How exactly does BRAVA work to achieve this goal. The BRAVA breast augmentation system is an organic combination of tissue-induced augmentation technology and fat grafting technology. the external expansion of the BRAVA system generates more and stronger vascular matrix for fat grafting before surgery, thus allowing more fat particles to be evenly distributed, creating conditions for re-vascularization between the particle and recipient contact interface, as opposed to creating a larger and more adequate matrix space for fat viability and growth. receptor matrix space for growth. American plastic surgeon Roger Khouri invented the Brava breast augmentation system based on the principle of tissue expansion, which was first used for physical breast augmentation, but later, this system was found to be a good aid for autologous fat augmentation. “The larger the capacity, the larger the “pocket” that can accommodate fat, thus increasing the amount of single fat transfer; secondly, it makes the blood vessels in the recipient area expand and proliferate, so that the fat growth soil becomes fertile, and for the transplanted cells, the blood-rich breast can increase the survival rate of autologous fat, which Not only does it increase the amount of grafting, but it also promotes the absorption of inactivated fat fragments. Therefore, Brava combined with autologous fat grafting can achieve better results than either method alone; Brava improves the conditions of the recipient area for autologous fat grafting, while fat grafting increases the target of Brava, and the two complement each other. Autologous fat generally requires 3 or more injections to achieve better results. The amount of fat grafting varies from person to person, with Westerners getting around 300ml per side at a time and most of our country getting around 200ml per side. Many candidates do not have enough fat in their bodies and have very small breast bases, so the effect of fat grafting is very limited. Brava assisted fat transfer can make the best use of limited resources, increase the amount of fat injected in a single session, and improve the survival rate of fat. Brava breast augmentation system is more suitable for candidates who do not have sufficient sources of autologous fat but want to have autologous fat augmentation, while Brava is also a better choice for candidates who have certain conditions but do not want to receive breast augmentation with implants, or for candidates whose general conditions do not qualify for the surgery.
