Liposuction actually has a long history with techniques that date back over 100 years. However, most of the important developments in modern liposuction have occurred in the past 3 decades. Tumescent liposuction made liposuction a mainstream procedure by reducing the blood loss associated with surgery, while ultrasound liposuction represented a major advancement for efficient removal of fat. However, ultrasound brought with it a higher rate of complication because of the heat produced by the equipment.
Finally, the Vaser company was able to utilize the best features of tumescent and ultrasound liposuction with an improved technology that produces minimal heat and therefore minimal complications. I would say that I am now using Vaser Liposelection for about 90% of my liposuction cases.
