If you want to enlarge or re-shape your buttocks and have discovered that they do not respond to diet or exercise, buttock implants may be the solution. Implants come in a variety of shapes and sizes and are made of soft silicone, which provide a firm, smooth yet natural feel. They are placed away from the bony area on which you sit. The procedure takes about two hours and is performed under general anesthesia. Incisions are made inconspicuously in the depression between the buttocks. It may be performed in conjunction with liposuction for a more dramatic change in contour.
