Among many breast augmentation methods, prosthetic breast augmentation is the longest and most experienced method in the world, so it is welcomed by many friends. It is very suitable for patients with small, flat and scar-free breasts. Proper size of breast prosthesis implantation can increase the size of breast, improve its shape and symmetry, and make the chest fuller. It has the advantages of safety, reliability and convenience for taking out. Prosthetic breast augmentation surgery is a method to achieve breast enhancement by implanting high-quality silicone prosthesis under pectoralis major through axillary or areola incision, so its life mainly depends on the length of breast prosthesis. How long is the life of prosthetic breast augmentation? The US Food and Drug Administration has also passed the long-term safety evaluation of silicone prosthesis to human body, allowing silicone prosthesis to be used in human body for a long time. However, the doctor still suggested that the prosthesis should be replaced every 10 years. Although there will be no uncomfortable reaction when the prosthesis stays in the body for a long time, with the accumulation of time, the quality of the prosthesis will decline, and the possibility of accidents such as leakage will be greatly improved. Replacing the prosthesis in time is more conducive to the long-term safety of the breast and can better maintain the effect of breast augmentation.
