Hello, thank you for your question regarding removing silicone previously injected into the buttock. There are two methods to remove silicone from the buttocks: liposuction and direct excision. Your plastic surgeon is partially correct in that silicone cannot be removed with traditional liposuction, BUT using intra-operative ultrasound, VASER-assisted liposuction, and a custom liposuction cannula, silicone and associated scar tissue can be removed from the buttock. I use buttock liposuction for mild to moderate cases of silicone butt. Buttock liposuction works well for patient with several small to moderate masses of buttock scar tissue. Alternatively, if your case is more severe with several hard silicone nodules and/or hard buttock scar tissue, you need an incision with direct silicone butt excision. The incision for silicone buttock skin, silicone, and scar removal can be placed horizontally on top of the buttock (like a seagull's wings), under the buttock, or vertically in the buttock crease. The placement of the incision and thus, the resulting scar depends on the location of the underlying silicone and scar tissue. I hope that I have answered your questions removing silicone from the buttock.
