Buttocks injections gone wrong (Photo)

The only option is surgical removal, you can try oral antibiotics, and antininflammatories even biologics.  But they are only mildly helpful.  Best, Dr. Emer.

Silicone biopolymers can cause severe longterm complications including inflammation and nodule formulation. Although results are longer-lasting that Juvederm or Restylane, long-acting fillers should be avoided.  
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.

Regards, 
Liquid silicone is unsafe, please do not use it ever. The autoimmune response could be triggered by this substance, if you look around on th Internet, you will find patients that have a lot of problems with this product. The use for lips and other areas is off label. The inical use is for retine problems. 
We need a nuclear magnetic resonance (MRI) to be able to have a more accurate diagnosis and thus be able to define the technique (videoendoscopy or open), but the biopolymers should be removed as soon as possible by surgery.

Please remember to be aware, do not let any permanenrt filler to be injected into your face, breast, buttocks, calfs, genitalia, etc. The safest way to increase buttocks is through your own fat injections or through silicone implants.
I hope the information was usefull, have a nice day! Dr Carlos Alberto Ríos.
