Hello nana30, Thanks for your questions! Foreign materials and filler injections included but not limited to Silicone, Biogel, Hydrogel, Biopolymer, PMMA, and Aqua gel are not-FDA approved for body contouring and are extremely harmful to the human body. The physical complications occurring from these injections include granulomas, lumps, bumps, itching, burning, skin discoloration, joint pain, tingling of the nerves, nerve damage, muscle damage, numbness, pulmonary edema, and possible loss of limb and/or life. It is important that patients who have had silicone and/or other non-FDA approved filler injections for body contouring (even without any manifestation of adverse effects) consult with an experienced plastic surgeon to be evaluated and discuss their particular condition and potential risks for complications. A Magnetic Resonance Imaging (MRI) scan may be necessary to determine the location of the injected material. The treatment varies from patient to patient, since no two cases are exactly the same. This may range from surgical excision, to hyaluronidase injection followed by VASER Liposuction and fat transfer into the area to correct the resultant deformity. With appreciation, Dr. De La Cruz.
