The second most popular cosmetic surgery procedure, liposuction sculpts the body by removing undesirable fat from areas such as the abdomen, waist, hips, buttocks, thighs, knees, chin, cheeks, neck and upper arms. Local anesthesia or general anesthesia may be used depending on the extent of the procedure and the operation lasts from one-to-two hours depending on the amount of fat being removed. Barring extensive weight gain, the results should be permanent. The procedure is performed in-office. Wearing an elastic garment support for two weeks is customary.
