VASER®-pulsed ultrasound is a relatively recent device, which utilizes ultrasound energy to emulsify fat tissue. The main differences from previous ultrasound technologies (i. e., UAL) concern safety issues. Owing to the excessive ultrasound energy delivered by first-and second - generation UAL devices, a series of complications arose including seroma, cutaneus burn, skin necrosis, and dysesthesia. The initial enthusiasm for UAL decreased due to the complication rate and the cost of equipment.
In 2001, VASER® appeared on the U. S. market as a new device delivering nearly half the ultrasound energy in comparison with the older machines. The shape and design of the new solid titanium probes increased the efficiency of the system.
Superficial UAL allows (through minimal skin incisions) the utilization of 2.2mm solid titanium probes to fully undermine the subcutaneous tissue, thus allowing excellent skin retraction. Deeper planes are treated with 2.9 mm or 3.7 mm probes for faster emulsification. Grooved probes increase efficiency of the system. Three alarms control the system and prevent mistakes (18). It is thought that the complication rate has dropped virtually to zero with the present device.

Lipoplasty has a threefold target: aesthetics, functionality, and restoration. But only surgeons properly trained in liposculpture may achieve this target. Lipoplasty is a surgical technique performed through mini-incisions. Thin tools, a few millimeters in diameter, are used under tumescent local anesthesia. Operations should be performed by surgeons who have experience in this field, under the control of anesthetists or cardiologists specialized in surgical monitoring.
