Liposuction is a surgical technique used to remove unwanted deposits of fat from specific areas of the body, including the face and neck, upper arms, trunk, abdomen, buttocks, hips and thighs, knees, calves, and ankles. The results of liposuction are a smoother and better proportioned body contour. Liposuction may be performed as a primary procedure for body contouring or may be combined with other surgical techniques such as facelift, abdominoplasty, or thigh lift procedures to tighten loose skin and supporting structures.
