Augmentation by prosthesis allows an increase in the volume of the breasts thanks to an implant. The implant constitutes a foreign body, generally very well tolerated by the body. Currently, it is considered that an implant should be changed every 10 to 15 years. The implant makes it possible to reach almost all breast volumes, provided of course that the morphology of the thorax allows it. Lipofilling uses your own fat. There is no implant, so it is the most natural solution possible. The result is final. On the other hand, lipofilling allows more moderate increases in volume than implants, and it sometimes takes several sessions to obtain the expected result. Finally, composite breast augmentation makes it possible to combine prostheses and lipofilling in order to obtain a very natural result.
