A form of liposuction in which several quarts of a solution are pumped below the skin in the area from which fat is to be suctioned. The saline (salt water) solution used includes the local anesthetic lidocaine to numb the area and the vessel-constrictor epinephrine (adrenaline) to help minimize bleeding. The fat is suctioned out […]

A form of liposuction in which the cannula is energized with ultrasonic energy to assist in the breakdown of fat tissue. This technique has an advantage in areas of scar tissue, such as the male breast, the back, and areas where liposuction has been performed before. Its disadvantages include the need for longer incisions in […]
