VASER stands for Vibration Amplification of Sound Energy at Resonance. This technology uses ultrasound waves to break up fibrous networks and allows the surgeon to expend less energy during the operation. Like power-assisted liposuction (PAL), this technology is especially helpful for large-volume fat removal, the removal of dense/fibrous fat, and in revision liposuction cases. While I sometimes use this technology, I cannot argue that this technology improves or changes my patients’ results.
