Autologous fat transplantation has been clinically applied for about 100 years, with the development of medicine has gone through several different periods, the earliest was applied to abdominal surgery, currently our most common application of granular fat tissue transplantation was developed with the rapid development of liposuction surgery, which is the modern real sense of fat transplantation since the 80s. Meaning: Autologous fat transplantation is to suck excess subcutaneous fat cells from certain parts of the human body itself, and then after the aspirated mixture is purified and processed by step-by-step methods to get compound fat granular tissue, select intact granular fat cells by way of injection and then transplant them to the parts of the body that need fat filling, such as multiple places on the face, temples, nose, nasolabial folds, chin, breasts, lips, etc., to achieve the purpose of correcting deficiencies or cosmetic and treating skin aging. Advantages: 1. Because all the transplanted tissues come from autologous tissues, their biological characteristics are far better than any prosthetic materials, so they are non-toxic and harmless to themselves, and will not produce immune reactions or rejection reactions. 2, will not cause changes in the endocrine environment of the human body, will not harm the breast itself, and will not have adverse effects on future fertility, breastfeeding. 3. It is easy to take fat particles for transplantation, and there are abundant sources of tissues. The fat is simply too cost effective compared to a 1ml hyaluronic acid of more than 5000 yuan and a collagen of about 10,000 yuan, and the hyaluronic acid is extracted from cattle, collagen is extracted from pigs, and the psychological problem is a big one. The actual fact that they only have a life span of six months to 2 years, compared to fat is too short-lived. 4.After fat transplantation, the local part feels soft and realistic, and from the psychological feeling, it is better and more acceptable to transplant with one’s own fat than the real feeling of artificial material prosthesis. 5.The method of extracting fat is wet vacuum liposuction with less trauma and less complications. The incision taken by this liposuction is generally about 3-5mm, so the scar after healing is very small and located in hidden parts (such as umbilicus, hip line, etc.). For people with more localized fat accumulation, it can also play a role in weight loss and slimming, shaping beautiful curves, and can be said to be able to reshape the three circumferences. Disadvantages: The survival rate of fat transplantation is low (generally about 30-70%), so each time you need to over-inject, and some people need several times to achieve good results, due to the unstable absorption is the biggest defect of this method, but also the focus of my current research direction, the current animal experimental research is progressing rapidly, the clinical also carried out a mixture of autologous bone marrow stem cell treatment, the effect is significantly improved, can The survival rate of transplanted adipose tissue is significantly improved, and the survival quality of transplanted fat is also significantly improved. The progress of basic research and improvement of surgical methods and the accumulation of experience are also the basis for the large number of fat surgeries we are currently performing. Indications: Autologous fat transplantation has a wide range of indications, such as for filling subcutaneous depressed facial defects or deformities, such as unilateral or bilateral facial atrophy, facial soft tissue dysplasia, depressions in the cheek, temporal, frontal and orbital areas, depressions caused by facial surgery or trauma, thin upper lip or short human middle, deep nasolabial folds, nose augmentation, chin augmentation, small earlobes, etc.; for congenital breast dysplasia, breast atrophy after breastfeeding, bilateral breast size Atrophy, bilateral breast size asymmetry, nipple depression deformity; for post-liposuction depression, soft tissue depression in other parts of the body, such as hip, thigh, calf bending, etc.; hand soft tissue atrophy (commonly known as chicken claw hand); genital reshaping, such as penis thickening, vaginal relaxation, atrophy, etc. Points to note: Autologous fat transplantation requires precise design and accurate positioning and quantification, which requires high technical requirements for doctors, and if the results are not good if done casually, it is more troublesome to repair. The purpose of autologous fat transfer surgery is to solve the problem of depressions, that is, to fill the local depressions to make the facial contour smooth, it is a rejuvenation surgery, so it will not make the face bigger or fatter. There is no need to worry about scars because from fat extraction to fat injection, there are only small stitches and no stitches are needed. Autologous fat has absorption problems, and each person’s survival varies. It may take two to three surgeries with at least three months between surgeries to achieve the best results.
