*3.3.5 Phase 2: simultaneous irrigation and aspiration*

Low infiltration settings were preferred over higher infiltration settings during Phase 2 to allow for more efficient aspiration of minimally turgid tissues. Once the skin-fat folds were distracted from the underlying muscle fascia, a slow, deliberate "to and fro" motion of the cannula was the most effective method for removing fatty tissue through the predetermined fan-shaped pathways. When dealing with denser fibrotic tissue, a cannula with a larger or sharper orifice was chosen. At 750 mm Hg of negative suction, a higher infiltration rate was found to be possibly more efficient for fat removal. A lack of fatty tissue withdrawn in the tubing, a decrease in the diameter of the grasped fat fold, and the occurrence of minimal resistance during repeated cannula passages were used to assess the clinical endpoint.
