The shape is divided into circular (high-end surface, high-end surface and low-end surface) and water drop type. At present, the round rough prosthesis is the most widely used. Choose different prosthesis shapes and specifications according to the individual's foundation (referring to height, weight, body shape and chest circumference), and commonly use high-end surface and high-end surface. Under normal circumstances, the chest is relatively small, the foundation is relatively flat, and the high-end face of es is selected more. Because the breasts are not well developed, they will feel softer. The chest is loose and the chest is big. If you have a certain foundation, you can choose Mantuo prosthesis. Whether Mantuo, ES or Meg are good prostheses, the probability of membrane contracture is very small.
