Hi, thank you for your questions regarding the removal of hydrogel from the buttock. I'm sorry you are having complications of hydrogel injections into the buttock. Most foreign body injections into the buttocks do eventually cause problems. You may have an autoimmune disease due to the hydrogel injections called ASIA syndrome. Nonetheless the hydrogel needs to be removed. ASIA syndrome is an acronym that stands for Autoimmune/inflammatory Syndrome Induced by Adjuvants. Adjuvants are agents (like silicone) that modify the effect of other agents (like causing scar tissue and pain). Typically, ASIA syndrome presents about 10 years after the injection. Since ASIA syndrome was first described as recognizable medical disease in 2011, most medical doctors do not know ASIA syndrome even exists. Patients with ASIA syndrome have symptoms due to injectables like PMMA and silicone. Symptoms include muscle pain with or without inflammation or swelling,muscle weakness, joint pain with or without swelling, chronic fatigue, non-restful sleep, sleep disturbance, neurological manifestations (like demylenation or MS), loss of memory, “brain fog”, low grade fever, or dry mouth. You have have some or all of these symptoms. The FDA warns AGAINST silicone injections on their website. The FDA states “Do not get injectable silicone or any type of filler material for large-scale body contouring or enhancement.” Also, the FDA has said Injectable silicone is permanent, with side effects that can occur right after the injection and up to years after treatment. Silicone spreads and migrates easily inside the body, which may worsen adverse events and make surgical attempts to remove the silicone oil more difficult or impossible. Silicone, when injected into areas with many blood vessels such as the buttocks, can travel to other parts of the body and block blood vessels in the lungs, heart, or brain. This can result in permanent damage to those tissues and lead to stroke or death.” I specialize in hydrogel buttock removal and subsequent buttock reconstruction. I am the Director and chief clinical investigator at the Institute of Silicone Removal. Since removing silicone from the buttock is a big procedure, please seek an experienced, board certified plastic surgeon with significant experience in removing hydrogel from the buttock. Do your research. Make sure they have performed many buttock hydrogel removal surgeries and have the before and after pictures to prove it. Carefully examine their before and after pictures and check their reviews on RealSelf. If you cannot find an experienced, buttock hydrogel silicone removal surgeon in your neighborhood, consider traveling out of state if you must. I hope that I have answered your questions regarding removing hydrogel from the buttock. Sincerely, Dr. Katzen.
