Water Assisted Liposuction and Brazilian Butt Lift. Our 37 year-old female patient underwent a Water Assisted liposuction procedure. Water-Assisted Liposuction (Body-Jet) is a technique that uses a cannula and suctions out the unwanted fat. The removed fat cells are harvested so that they can be transferred/grafted to another part of the body, such as for a buttock lift. Using a gentle spray of sterile salt water to isolate and remove the fat cells, this method allows 80% of the removed fat to be grafted, compared to approximately 60% with traditional techniques. With all of the extra fat that was removed, Dr. Tehrani then did an autologous fat transfer to buttocks for a brazilian butt lift.
