When considering a liposuction procedure one consideration is the comparison of ultrasonic liposuction versus VASER liposuction. Ultrasonic liposuction is a technique first used back in 1987 and is not really a new technique. Most changes to ultrasonic liposuction have come from the introduction of tumescent fluid to numb and swell the fat cells to be removed through ultrasonic liposuction and by the introduction of 3rd generation cannulas.
One danger of ultrasonic liposuction is that the cannula generates heat and this heat can in turn cause significant burning if not kept constantly in motion. One potential side effect of the cannula is a burning of the skin from the inside out causing severe pain, scarring or necrosis (skin death). Another dangerous side effect in the hands of an unskilled surgeon is perforation of the bowels as the cannula is not blunted. In addition ultrasonic liposuction will weaken the cannula over time and if a cannula breaks inside a patient exploratory surgery is required to recover the pieces.
VASER stands for Vibration Amplification of Sound Energy at Resonance. In short VASER uses the same principles of ultrasonic liposuction, using sound waves to break apart fat cells. The claim of VASER is that the frequency of sound used is targeted specifically at liquefying fat cells with minimal damage to surrounding nerves, blood vessels and connective tissues.
When reading through testimonials there appears to be know clear consensus as to whether or not VASER liposuction is better than ultrasonic liposuction, tumescent liposuction, smart liposuction or even traditional liposuction. VASER liposuction can still cause significant amounts of pain and swelling.
A general consensus among medical professionals is that satisfactory liposuction results both short term and long term are the result of the surgeon and not the liposuction technique used. A good surgeon should be familiar with several types of liposuction and be able to explain which procedures he or she uses and give you a recommendation of what type of liposuction he or she feels is most appropriate.
Be discriminatory when choosing your surgeon and procedure. Inquire about their credentials, the number of surgeries they've completed, potential risks and benefits, other alternatives to liposuction and what to expect for recovery and pain management. When reading through information try to find not only what the side effects might be but also the percentage of occurrences during surgery to keep things in perspective. Ask your surgeon what he thinks of the comparison between ultrasonic liposuction versus VASER liposuction.
