The removal of fat cells by using a sound wave is known as VASER liposuction. Because VASER only emits a sound wave that affects the fat cells, the surrounding tissue is not damaged. Because it liquefies the fat cells, it is possible to remove more fat than traditional liposuction method. Instead of using manual movement to break down the fat tissue, vaser liposuction uses high frequency vibrations to break fat cells apart, leading to less pain and minimal bruise formation.
Surgery is usually performed under general anaesthesia. In small area applications, local anaesthesia may be preferred. The edema occurring postoperatively disappears within an average of 10 days and a significant tightening begins to be observed by the third week.
