Since each technique has the same ultimate goal, all three involve dislodging and isolating fat for removal. In addition, regardless of the technique selected, the surgeon makes tiny incisions into the skin to insert small tubes, or cannulas through which the isolated fat is removed. The incisions are then carefully closed in a way which prevents the likelihood of bleeding or swelling. Depending on the technique selected and the amount of fat being removed, this procedure may be performed under a local or general anesthesia and can last from thirty minutes to several hours. In some cases, your surgeon may recommend combining liposuction with other surgical procedures in order to achieve your desired results.
