It requires a prerequisite which is to have sufficient fat capital. Thus it is possible to perform a unilateral breast augmentation (correction of breast asymmetry) or bilateral (correction of congenital breast hypoplasia or secondary to pregnancy, weight loss ...). The "ideal" case is that of a woman with breast hypoplasia with a gynoid distribution of excess fat (belly, thighs, hips, calves, etc.) allowing at the same time the operation to refine the silhouette and increase the breast volume. It is also possible to improve by this method certain breast augmentation by breast prostheses thus achieving what is called the composite method. It is also possible to reconstruct a breast by breast fat transfer or breast lipofilling. The development of this surgical technique This method has developed over the past ten years and in certain cases where it is achievable, provides good results knowing that a significant part of the fat reinjected into the breast can melt in a proportion of 30 at 60% .If necessary and feasible, consider a second breast lipofilling procedure. The general complications of the surgery are the same (infection, hematoma, hemorrhage, phlebitis, see pulmonary embolism, etc.).
