Hi, thank you your question regarding how long after having the silicone in my butt removed could you be able to do a fat transfer to reshape any deformity the removal of silicone from the buttock. You should wait at least four months after silicone removal before you consider a fat transfer or BBL. Waiting four months gives your body enough time to heal from the surgery and establish new blood supply. New blood supply is necessary for successful fat transfer to the buttock. The wound VAC is not necessary in most silicone removal cases; if the wound is left open and there still is silicone in the wound, a wound VAC may be a good idea. However, for the most part, a wound VAC is not necessary. You must understand the wound VAC is placed on top of the skin and does not decrease the incidence of a seroma. Wound VACs are on the outside of a closed surgical incision. Whereas seromas are on the inside of a wound under a closed surgical incision. I would not tell your plastic surgeon what to do, but rather follow what your plastic surgeon recommends. Thank you for questions regarding butt reconstruction after silicone removal and the use of the wound VAC. The FDA warns AGAINST silicone injections on their website. The FDA states “Do not get injectable silicone or any type of filler material for large-scale body contouring or enhancement.” Also, the FDA has said Injectable silicone is permanent, with side effects that can occur right after the injection and up to years after treatment. Silicone spreads and migrates easily inside the body, which may worsen adverse events and make surgical attempts to remove the silicone oil more difficult or impossible. Silicone, when injected into areas with many blood vessels such as the buttocks, can travel to other parts of the body and block blood vessels in the lungs, heart, or brain. This can result in permanent damage to those tissues and lead to stroke or death.” I specialized in silicone buttock removal and subsequent buttock reconstruction. I am the Director and chief clinical investigator at the Institute of Silicone Removal. Since removing silicone from the buttock is a big procedure, please seek an experienced, board certified plastic surgeon with significant experience in removing silicone from the buttock. Do your research. Make sure they have performed at least 100 buttock silicone removal surgeries and have the before and after pictures to prove it. Carefully examine their before and after pictures and check their reviews on RealSelf. If you cannot find an experienced, buttock silicone removal surgeon in your neighborhood, consider traveling out of state if you must. I hope that I have answered your questions regarding long after having the silicone in my butt removed can you do a fat transfer to reshape any buttock deformity. Sincerely, Dr. Katzen.
