Vaser liposuction employs ultrasound energy to efficiently disrupt fat before traditional suctioning, resulting in reduced operation time and easier suction. Studies indicate that Vaser liposuction leads to better skin tightening and less blood loss compared to regular liposuction, although pain levels appear similar. The technique is particularly effective in fibrous areas and can enhance body sculpting outcomes, including fat grafting for Brazilian butt lifts.

1. Vaser liposuction
What is it?
Is it better than regular liposuction?
Vaser ( vibration amplification of sound energy at resonance )liposuction uses
ultrasound energy to disrupt the fat before suction liposuction is performed. Having
used Vaser for almost 2 years I can say that it cuts my liposuction time by 50% and the
suctioning is much easier to perform. Patients that have had previous liposuction or
with large weight losses can be fibrous and be difficult to do. I am noticing better results
with patients with more uniform fat reduction and more skin tightening.
Vaser liposuction is very similar to regular liposuction except a Vaser probe is placed
under the skin and ultrasound energy is delivered to the subcutaneous area to disrupt
the fat prior to liposuction. This is done after the numbing solution is placed under the
skin. I really like the Vaser better than all the laser probes out there because the Vaser
probe is larger and I can treat larger surface areas.
There was a study published 2012 that was multi-center, prospective, randomized,
single-blind, controlled clinical trial comparing the VASER- to regular suction liposuction.
They performed Vaser liposuction on side of the body and regular liposuction on the
other side of the body. They measured changes in ultraviolet light tattoos to asses the
amount of tightening the patients had. What they found was that the side where the
Vaser was performed they found more skin tightening which was statistically significant
to the p=0.003. This means there was much more skin tightening with the Vaser.
They also measured blood loss in the two aspirates and found that the Vaser had
statistically significant less blood loss1. This study did not show a statistical difference
in subjective measure such as pain and swelling.
I love using the Vaser on body parts that are very fibrous such as the upper back and
abdomen. The inner thighs and arms also produce nice results with good skin
tightening. Even though the previous study did not show a statistical significance in
terms of postoperative pain, I feel antidotally, these patients have less pain than with
traditional suction liposuction.

Patients want to be sculpted and Brazilian Butt lifts are being requested more
frequently. The fat that is removed from the flanks are frequently put back in the butt to
improve the contour and increase projection of the butt. A recent study from 2013
documented that the fat that is extracted with the Vaser has a viability of 85-88%.2
Taking body sculpting to the next level we get what is called Vaser Hi Def of the
abdomen, arms and back. I will talk about that more in a future blog.
