Is power-assisted liposuction (using oscillating or vibrating cannulas) safe and effective?
Power assisted liposuction (PAL) uses a machine-powered cannula that oscillates in and out or vibrates very fast. PAL is relatively new and somewhat controversial. Manufacturers of these devices and some surgeons are enthusiastic about PAL and believe it makes liposuction easier. Other surgeons remain skeptical and have not found there to be any advantage in using PAL.
