Treatment time will vary depending on the size of the area and the amount of fat being removed.  Liposuction may be performed under a local anesthesia which numbs the affected areas, usually combined with intravenous sedation. For more extensive procedures a general anesthesia may be used.  During the procedure the surgeon will insert a narrow tube called a cannula through a tiny incision.  The cannula is pushed and pulled through the fat layer breaking up the fat cells and suctioning them out.  Surgeons may use a “dry” technique, a “tumescent” technique that introduces large amounts of fluid.   After surgery, you will be required to wear a supportive corset or pressure bandages around the treated areas.
