How do you remove biopolymers from buttocks?

Hello, thank you for your question regarding removing an unknown product from your buttocks.  It was probably silicone that was injected into the buttocks.  There can be many reactions to unknown substance injected into the buttocks, especially silicone.  The foreign body causes an inflammatory response.  Buttock scar tissue is created.  Often, the buttock skin reacts and becomes red.  All this scarring can create a granuloma.  Over time, granulomas can turn into cancer.  I would suggest you have this product or silicone removed from your buttock at once.  I use a technique called intra-operative ultra-sound guided VASER assisted liposuction for the removal of buttock silicone and buttock scar tissue.  Another technique for the removal of buttock silicone is direct removal.  These are highly successful procedures.  Before you make any decisions regarding silicone removal from the buttock, I would suggest you seek consultation with an expert. Please seek an experienced, board-certified, plastic surgeon.  Travel out of state if you must to find such a silicone removal  expert. If you have any more questions regarding silicone removal from the buttock, intra-operative ultra-sound guided VASER assisted liposuction or plastic surgery in general, please contact my office.  Sincerely Dr. Katzen.

Hi Gavinosmom,
I perform hundreds of silicone removal procedures every year, and what I've learned is that open, surgical removal is the safest and most reliable way to remove this foreign body substance. I perform my procedures in two stages- removal followed by reconstruction.
I urge you to find a board certified plastic surgeon who specializes in this condition.
Best of luck on your search for treatment!

Silicone biopolymers are being used throughout the world for facial and body volume augmentation. Results are longer-lasting that Juvederm or Restylane. 
Bellafill and Artefill are known to cause granulomas and permanent nodules with swelling. This is not the case for everyone. Silicone biopolymers can also cause similar chronic inflammatory conditions. 
In my practice, I specialize in the removal of Bellafill and Artefill injections, in addition to silicone biopolymers, from the face and body. Initially, treatments are non-surgical with corticosteroids and immune modulators. If unable to be corrected, we can also perform surgery in some cases. 
Silicone biopolymers can also be removed from the body if there are signs of migration or inflammation. All of these filler-types should be removed as early as possible. 
Lastly, our office is conducting ongoing studies of plasma-assisted corticosteroid application, which allows for diffusion of the treatment medication in superficial tissue without causing atrophy. 
Best,
