Thank you for your question about buttock augmentation with buttock implant after PMMA injections. Buttock PMMA removal and subsequent buttock reconstruction is a large portion of my plastic surgery practice. First, the PMMA needs to be removed surgically. Then, about 4 to 6 months later, the buttocks can be reconstructed with FDA approved, semi-solid silicone buttock implants. I hope that I have answered your questions regarding buttock augmentation with buttock implant after PMMA injections. I specialize in buttock implant insertion after PMA removal. If you have any more questions regarding buttock implants, buttock implant surgery, buttock implant insertion, or buttock implant revision, please contact my office. Since buttock implant surgery is a big procedure, please seek an experienced, board certified plastic surgeon with significant experience buttock implant insertion. Do your research. If you cannot find an experienced, buttock implant plastic surgeon in your neighborhood, consider traveling out of state if you must. Sincerely, Dr. Katzen.
