Liposuction is used to improve the contour of the abdominal area alone or in combination with one of the surgical – abdominoplasty – procedures. The technique of liposuction involves removing unwanted fat using long narrow devices called cannulas. The incisions used for liposuction are very small and are usually placed within skin folds or hidden within the umbili cus (belly button). The ends of the cannulas have small openings through which the fat is suctioned away with care and precision.
