How long after silicone removal from the buttocks can I get a proper board certified BBL?

You will probably need 3 months or so after removal. It may not be possible to remove all of the material due to lack of visibility, injection into the muscle or more deeply, etc. This removal inevitably creates contour deformities, which can be difficult to correct with fat grafting. If you are going to do this, find someone who does these types of complicated procedures and can get you a reasonable result.I perform about 500 Brazilian buttlifts each year, and this
procedure is the most surgeon dependent plastic surgery procedure. Find
a plastic surgeon with ELITE credentials who performs hundreds of
Brazilian buttlifts each year. Then look at the plastic surgeon's
website before and after photo galleries to get a sense of who can
deliver the results. Kenneth Hughes, MD Los Angeles, CA

You will need to wait 6 months before having a brazilian butt lift. You need to let the surgical area heal properly before having fat transfer to the buttocks.

Its a good idea to get this taken care of before an issue. If you were my patient I would require a year and probably a second return to the OR just to make sure all of the black market material was gone

Hello dear!!
Thanks for the question and provided information as well. 
I would recommend to wait six months between surgeries, but remember that all depends on your health and lab tests.
l suggest you to make an appointment with a board certified plastic surgeon to talk about your goals and anything you need to know.
Good luck :)

You would have to be evaluated in person. It is very difficult to almost impossible in some cases to remove micro-droplet silicone completely that has been injected.

If one can localize the injected silicone in an area, then it can be removed. Remember one can never remove all the silicone injected. A CT scan can localize the bulk of injected silicone. Reconstructing the buttock defect afterwards depends on the healing and the softness of the area, may go 3-6 month before the fat transfer.Samir Shureih MD. FACSsshureih@msn.com
