The Efficacy of Powered Liposuction

BACKGROUND: Powered liposuction is a relatively new innovation for more efficient removal of adipose tissue. OBJECTIVE: To evaluate the effectiveness of powered liposuction in removing adipose tissue when compared to traditional liposuction. METHODS: Four powered liposuction devices were evaluated in the power on mode vs. the power off. The fat extracted in each of these modes was measured in a mucous specimen trap. RESULTS: There was increased fat extraction in the powered mode for all instruments. The increased rate of fat extraction varied from 20 to 45% between instruments. the overall increased extraction in powered vs. nonpowered mode was 30%. CONCLUSION: The powered liposuction devices tested significantly increase the efficacy of subcutaneous fat removal during liposuction.
