The tumescent technique is a relatively new liposuction method that can reduce post operative bruising, swelling and pain. Blood loss is minimized during tumescent liposuction.

In the tumescent technique, areas of excess fat are injected with a large amount of anesthetic liquid before liposuction is performed. The liquid causes the compartments of fat to become swollen and firm or "tumesced." The expanded fat compartments allow the liposuction cannula to travel smoothly beneath the skin as the fat is removed.
