In recent years, with the development of fat aspiration and weight loss surgery, there are more and more reports of injecting the aspirated fat tissue into the breast for breast augmentation, which can achieve the effect of using waste and killing two birds with one stone. However, this method is not very mature and needs to be continuously explored and improved. At present, it is believed that the amount of granular fat injection for breast augmentation should not exceed 60 ml per side, and the interval between each two injections should not be less than one month. After several injections it is expected to achieve the fullness of normal female breasts and can be applied to small breast deformities that are flat or mildly sagging. Too large a single injection will lead to unpredictable results or complete absorption with no efficacy or fat liquefaction and necrosis leading to serious consequences. Although the size of the breast is a private matter for a person, it plays a considerable role in social culture and psychology. Since the size and shape of breasts are mainly influenced by genetics, improving their shape and size through diet, exercise and medication ultimately has little effect. Breast augmentation is a possible way to change the shape and size of the breasts, given the current state of technology and medical treatment. In the Oriental context, breast augmentation is done by placing implants behind the pectoralis major muscle, the most commonly used implants are silicone gel, hydrogel and saline. They come in different shapes, sizes and materials, some are hemispherical and some are teardrop-shaped. As for the surgical incision, different incisions are used according to the surgeon’s practical experience, anatomical structure and the concealment of the incision. The most commonly used incisions are the axillary incision and the areolar incision. The advantages of these two incisions are that the surgical scar is almost invisible and they are both conducive to the separation of the appropriate size and shape of the implant placement cavity. At present, scholars believe that it is safe to place the prosthesis in the posterior pectoralis major muscle space.
