VASER liposelection is 3rd generation ultrasound assisted liposuction technique. After injection of tumescent solution special solid titanium VASER cannulas with grooved tip, is introduced into fatty layer through small cuts in skin and surgeon moves the cannula gently back an forth delivering ultrasound energy evenly to the tissue. Ultrasound selectively breaks down fat cells without causing collateral damage to blood vessels, skin, nerves or fibrous tissue. This is why its called VASER liposelection. After the fat is liquefied with VASER energy, it is suctioned out with hollow cannulas as usual.
