A cannula is provided with a guide bar extending in spaced, parallel relationship to the cannula. Adjacent and overlying a hole formed in the cannula tip through which suction is applied to surgically aspirate fatty tissue is a guide surface adapted to contact and slide against the skin of a patient while the cannula tip is manually directed by the surgeon through the fatty tissue in reciprocating strokes. The guide surface maintains the tip at a constant depth within the tissue so that, upon completion of suction lipectomy, a desired amount of fatty tissue is surgically aspirated while leaving an even thickness layer of tissue intact. A new surgical procedure for performing suction lipectomies with the guided cannula of the invention is also disclosed.
