Liposuction is the procedure used to remove excess areas of fatty tissue from specific areas of the body. It can be performed on just about any area of the body including cheeks, jowls and neck, chest and breast area, upper arms, back, waist, hips, buttocks, inner and outer thighs and knees, calves, and ankles. Liposuction permanently removes a portion of the fat cells and so patients tend not to regain weight in that area, making it a very desirable surgical procedure.
