Autologous breast augmentation is breast augmentation with autologous fat injection: that is, fat is extracted from the parts with local fat accumulation (abdomen, waist, etc.) and injected into the breast. Autologous breast augmentation not only solves the trouble of flat breasts, but also solves the trouble of having extra fat in the abdomen or waist. Autologous breast augmentation is suitable for some cases as follows: primary breast dysplasia, spontaneous breast atrophy after pregnancy; breast dysplasia after breast tumor surgery, after trauma; asymmetry on both sides of the breast or those with mild sagging. The operation of autologous breast augmentation is introduced: The operation is performed under local anesthesia and the patient is awake. The swelling solution prepared by saline and sodium bicarbonate is injected into the area where the fat is to be extracted to make the local swelling white, and the mixture with fat and dermal blood is extracted by suction needle and processed to make the pure fat particles. After calculating the amount of left and right side injections, the aspirated fat particles are injected into the deep surface of the breast glands and the surface of the pectoralis major muscle with an injection needle outside the bilateral breast to achieve the ideal shape. Pre-operative and post-operative care and precautions: Like other surgeries, autologous granular fat injection breast augmentation should be avoided during menstruation as much as possible, no history of oral aspirin and anticoagulant drugs within half a month; no infection in the surgical area and fat aspiration area; adequate psychological preparation for surgery; no recurrence and metastatic tendency of tumor, mastectomy alone more than 3 years after breast cancer surgery); bath and clean skin should be taken before surgery. Infusion for 3 days after surgery to keep the dressing dry. Breast augmentation is a method of breast augmentation by implanting silicone gel implants under the mammary gland or pectoralis major muscle through concealed surgical incisions to achieve the effect of breast shaping and augmentation. After decades of clinical application, this method has been recognized by the international plastic surgery community as the preferred method of breast augmentation and is also a popular modern breast augmentation method. Breast augmentation is a surgical procedure that requires a small incision in the armpit or under the breast or areola, then the pre-selected breast implant is placed under the mammary gland or pectoralis major muscle, and after observing the breast shape and position, the wound is sutured and the stitches are removed in a week. Safety: A large number of clinical practice has proved that the implants are non-toxic, harmless and non-functional to the human body, and will not cause harm to the human body. Reliability: The implant can quickly create natural, realistic and beautiful breast shape and keep it for a long time. Removability: Because the implant is an independent entity in the breast, it is clearly bounded by the human tissue and is surrounded by a layer of fibrous tissue without interpenetration and adhesion, so in case of problems, it can be removed completely and thoroughly at any time. Prosthesis sources are abundant: various types of prosthesis can be mass-produced, and they are available at any time. Domestic prosthesis, joint venture prosthesis, imported prosthesis products at will. Wide range of adaptation, beautiful shape: No matter what type of small breasts, they can be suitable for this method to increase the volume of the breast. The implant is a soft and shapely entity with a certain degree of support. Not only can it make small or flat breasts full and firm, but also the augmented breasts have a realistic shape and feel and a beautiful appearance.
