Silicone buttock implants are made from solid silicone material customized to fit the size and shape of your buttock deficiency. Since the implants are placed intramuscularly and deep to the skin, patients do not feel the firmness of the implants as being unnatural. There may be transient buttock numbness following surgery but this will subside over several months. Since buttock implants are customized for each individual, the surgeon is able to improve the look of your buttock region by correcting buttock deficiencies specific to you.
