Liposuction is a surgical technique that improves the body’s contour by removing excess fat between the skin and muscle. Liposuction involves using a small stainless steel tube, called a cannula. The cannula is connected to a powerful suction pump and inserted into the fat through small incisions in the skin. Fat removal is accomplished as the suction cannula creates tiny tunnels through the fatty layers. After surgery, these tiny tunnels collapse, resulting in an improved body contour.
