Simplified view of liposuction will be presented. Liposuction (and all of the "million" variations of it) involves fat removal using thin cannulas attached to a suction power device. This part is virtually the same for all units available. The part that is different is the means by which the fat is "broken" down PRIOR TO THE ASPIRATION (removal of fat).
- Traditional liposuction units use cannulas with holes, with which the surgeon mechanically breaks the fat and aspirates at the same time by moving the cannula back and forth.
- Power-assisted liposuction units use an external power source, which causes movement of the cannula itself, in addition to the movement back and forth by the surgeon.
- Ultrasonic liposuction units deliver ultrasonic energy to break down the fat. Depending on the unit, fat is aspirated concurrently or separately (but during the same surgery) using a suction cannula. VASER is an example of an ultrasonic unit.
- SmartLipo (laser) unit uses light energy (i.e. laser) to break down the fat PRIOR TO THE ASPIRATION. At times, if a small area is addressed, fat aspiration may not be performed, as the body over time will absorb the broken down fat.
So what really is the difference between the various units if they all end up with ASPIRATION AS THEIR FINAL STEP? Basically, the energy source required to break down the fat:
- Mechanical (Surgeon)
- Power Assisted (electrical/gas power + Surgeon)
- Ultrasound
- Light (Laser)
The purported benefits of the latter two are they result in less trauma to the tissues, implying less recovery, less swelling, etc. Furthermore, because energy is also delivered to the undersurface of the skin as it is being delivered to the subcutaneous fat, some skin tightening can be seen. This is more true of SmartLipo (laser) unit.
Several caveats:
- Obviously, the overall recovery time is very dependent on the magnitude of liposuction performed - irrespective of the unit used. Small volume liposuction requires less recovery than larger volume liposuction.
- Even with the latest technological advancement, the the outcome is largely dependent on the operator (i.e. the surgeon) and the candidacy of the patient (determined by the surgeon).
- Excellent results can be seen with ALL UNITS, likewise, less than ideal outcomes can be seen with all units, as the unit is only as good as the operator using it. Some inherent advantages of VASER, SmartLipo units can be potentiated in selected patients IF THE RIGHT PATIENT IS SELECTED.
- Surgery is surgery. All surgeries have inherent risks and potential complications. Please do not trivialize any surgical procedure, despite what you read and hear. Consult your local professional about the various options, benefits, potential complications and limitations and be fully informed prior to any procedure.
