A liposuction cannula with abrading suction apertures and a method of using a cannula with abrading suction apertures are disclosed. The liposuction cannula comprises: a hand-holdable housing (24) having a cavity; a cannular tube (10) having a distal end and a proximal end, the proximal end of the cannular tube being insertable within the cavity; and a plurality of abrading suction apertures (14) about the cannular tube distal end. The abrading suction apertures (14) can be arranged in a variety of configurations, for example, axially about the distal end of the cannular tube, radially about the distal end of the cannular tube or angularly about the distal end of the cannular tube. The abrading suction apertures include a hole, and an abrading member which may be a raised leading edge, a depressed trailing edge, or both a raised leading edge and a depressed trailing edge.
