The advantage of autologous fat breast augmentation is that there is no rejection obstacle, and the disadvantage mainly has the possibility of infection or bleeding. 1. Advantages: autologous fat breast augmentation transplantation material is autologous tissue, biological characteristics are better than other heterogeneous materials. Autologous tissue has no rejection barrier and will not produce rejection reaction. 2. Disadvantages: Autologous fat breast augmentation may cause infection during liposuction or fat injection if the vessels or fat are not sterilized properly. In addition, during the injection process, if the small blood vessels of the breast are injured, or if the patient has coagulation disorder, or if the postoperative pressure bandage is not properly applied, it may cause bleeding. In addition, a one-time breast augmentation with autologous fat may not achieve the desired results and may require multiple surgeries. If you have the idea of cosmetic surgery, you must choose regular hospitals and regular doctors, and if any adverse reaction occurs, consult your doctor in time for treatment as soon as possible.
