You can get a modest increase in buttock size and shape with liposuction of the abdomen, sides, back, and legs and transfer of that fat to the buttocks. This procedure is highly surgeon and technique dependent. The thinner patient requires an expert at liposuction to remove as much fat as possible while leaving the skin smooth. Find a plastic surgeon with ELITE (education, experience, training, certification by the American Board of Plastic Surgery) credentials who performs hundreds of BBLs each year. Then look at the plastic surgeon's website before and after photo galleries and read patient reviews. Kenneth Hughes, MD, Board Certified Plastic Surgeon Los Angeles, CA
