VASER Liposuction: Why the Ultrasonic Technique is Superior

Posted on July 12, 2010 | by

This video features Dr. John Grossman discussing VASER Liposelection. He even performs a demonstration, not with an actual patient but using Crisco to show how VASER emulsifies fat prior to removal.

VASER is an advanced form of liposuction that uses ultrasound technology to provide superior results in body-contouring and fat reduction. It’s different than both traditional tumescent liposuction and laser liposuction. Using mechanical and acoustic forces, body fat is emulsified in the targeted area – without destroying fat cells or significantly damaging surrounding tissues.

How VASER Works

Just like the tumescent technique, fluid saturates the targeted areas before fat is removed. This fluid contains small gas bubbles that become dispersed throughout the tissue. Your surgeon then applies ultrasound pressure waves using the VASER system, which causes the bubbles to rapidly expand. The expanding gas bubbles force the fat cells to become dislodged from the surrounding tissue matrix. The fat cells are then emulsified and removed with the tumescent fluid.

Why VASER is Superior

The main advantage of the ultrasound-assisted technique with VASER is its “selectivity.”  Because the small gas bubbles are not interspersed between other tissues (blood vessels, nerves, etc), they do not act upon them during the procedure. Trauma to surrounding tissues is thereby reduced, meaning you get precise results with a shorter recovery time.
