Autologous fat particle injection auto-transplantation (fat particle injection auto-transplantation) is the method of injecting the purified fat particles obtained from suction into the soft tissue defect area with a syringe, that is to say, reusing your own fat. Advantages of autologous fat injection and transplantation: 1, in line with Millard’s “Robin Hood” principle: other parts of the rich or excess fat tissue, transplanted to the lack of soft tissue. 2, the use of autologous similar tissue to transplantation. 2, the use of autologous similar tissues to fill defects, most of the causes of body surface defects is subcutaneous soft tissue defects, the use of similar subcutaneous fat tissue filling, its shape, texture and the surrounding tissues are consistent. 3.The principle of thrift: the normal tissue discarded by previous fat suction is reused to reshape the body and correct the defects. 4, the donor area can form an ideal shape: fat grafting in the correction of defects in the recipient area at the same time, the donor area for the beautification of suction, shaping, to achieve at the same time to beautify the recipient, the donor area of the form without impairing its function. 5, belongs to the autologous tissue transplantation: safe and no rejection reaction, is the biggest advantage of fat transplantation. After each injection, most of the transplanted fat survives and can be repeated many times. 6, other: fat particles are easy to obtain, little tissue damage, easy to operate, lower cost, rapid recovery after surgery, no serious complications. The application range of autologous fat particle injection transplantation: The application range of fat particle injection transplantation is very wide, and it is suitable for filling depressions in any part of the body. Mainly include: depressed scar, facial depression, small jaw deformity, earlobe augmentation, uneven skin after liposuction, buttock filling and shaping, facial wrinkles, nasolabial folds (decree lines) filling, hemifacial atrophy, fingers and back of the hand wrinkles, breast deformity, nipple invagination deformity, facial paralysis sequelae, mild to moderate jaw retraction, cleft lip and palate, craniofacial deformities, penile augmentation, labia augmentation, etc., and as an auxiliary means of other surgeries. Auxiliary means. Autologous fat particles injection and transplantation requires certain techniques: in order to ensure the survival rate of transplanted fat, doctors should strictly follow the principle of minimally invasive in all aspects of fat suction and injection and transplantation to minimize the damage of fat cells. Only live fat cells can achieve the effect of filling; necrotic fat cells, no matter how much transplantation, or be absorbed, or rotting. Completely unable to achieve the original effect of fat grafting. Therefore, fat grafting is quite difficult for doctors without enough experience, and doctors who are able to perform fat suction are not necessarily able to perform fat grafting.
