Dear butthead, Unlike fat injection to the butts which disappear completely or almost completely after 6 - 12 months, silicone butt implants do not disappear. They do not have to be replaced unless they break and in my over 12 years of experience with butt implants surgery it never occured. The 2nd most important factor, after selecting the right surgeon, is following up on doctor's instruction post operatively. Deviating from those instruction can result in complications like hematoma, wound break down, infection and implants displacement that might result in implants removal or corrective surgery. So, when you decide to have butt implants surgery, you have to have total commitment to the recovery process. Additionally, do your due diligence because not all results are the same since there are different techniques and the implants come in different shapes, size and softness. Always, consult with board certified plastic surgeons who operate in accredited surgery center. Most importantly, check the before and afrer pictures to make sure that they are numerous, consistent and attractive. Check also the 'realself' reviews for positive patients experience which provides important information on the surgeons. Best of luck, Dr Widder
