PAL uses an up and down, vibrating-like motion of the cannula to acquire greater fat removal. When compared to simple suction-assisted liposuction, PAL requires less energy for the surgeon to operate while also resulting in greater fat removal. It is commonly used for difficult, secondary, scarred areas, and when harvesting large volumes of fat for transfers to other areas.
A technique called “tumescent liposuction" is the most common method for removing fat around the stomach, buttocks, thighs and ankles. It’s also considered the safest. “Tumescent” means that large amounts of buffered salt water are injected into fatty tissue beneath the skin. The doctor makes a cut in the fatty area to be treated, then inserts beneath the flesh a strawlike tube called a cannula that is attached to a vacuum. At the end of the cannula is a stiff wand. The doctor moves it back and forth in rapid motions to loosen fat. The procedure takes 45 minutes to two hours, with a recovery time of up to two weeks. The full effect of liposuction is seen six to 12 weeks after the procedure is performed. After the procedure, the area is bandaged and the patient must wear a compression garment for one to two weeks. Pain and bruising may last up to two weeks, and swelling may last for two weeks to two months.
