VASER-Assisted Lipoplasty delivers superior results in skin retraction and blood loss

Oct 26 2009

At the 78th Annual American Society of Plastic Surgeons Annual (ASPS) Meeting, Dr. Paul Vanek presented a study that confirms that VASER-Assisted Lipoplasty (VAL) delivers superior results over traditional Suction-Assisted Lipoplasty (SAL) in skin retraction and blood loss.

In a study called "A Multi-Center, Prospective, Randomized, Single-Blind, Controlled Clinical Trial Comparing VASER-Assisted Lipoplasty and Suction-Assisted Lipoplasty" results showed that the VASER Lipo treatment demonstrated 53% improvement in skin retraction per mL of aspirate removed relative to the standard SAL method, and a 26% reduction in blood loss. This is the first study to demonstrate statistically significant and clinically relevant improvements in a new lipoplasty technology relative to SAL. This prospective study used a contra-lateral (side-by-side) study design to evaluate post-operative differences between the two techniques over a six-month time period.

"Physicians have been reporting skin tightening benefits and reduced blood loss with the VASER Lipo System since the technology was released in 2002," said Dan Goldberger, CEO of Sound Surgical Technologies LLC. "This study now provides empirical evidence of yet another advantage of using VASER ultrasonic energy in all body contouring procedures."

The study involved twenty female patients between the ages of 20 and 48 who received contra-lateral treatment with traditional liposuction and VASER Lipo in one or more anatomical regions that included the upper arms, upper back, flanks, outer thighs, and inner thighs for a total of 33 regions. Patients were blinded to the technology that was used on them and aspirate was kept separate and analyzed for blood content. Skin retraction was measured using changes in UV tattoos placed prior to surgery.
