External ultrasonic lipoplasty: an effective method of fat removal and skin shrinkage.
External ultrasonic lipoplasty is an effective method for the removal of localized fat and the fat due to moderate obesity. The ultrasound is externally applied and transmitted through the skin surface. The acoustic waves are selectively absorbed by previously injected tumescent fluid and fat. It is the combination of this acoustic wave and ultrasound-induced fluid streaming that facilitates fat removal. Multiple, 2.5- to 3.7-mm incisions are made, through which standard thin (2.3 to 3.5 mm) suction lipectomy cannulae are used to aspirate the emulsified fat and oil. A major advantage of this procedure is that superficial subdermal liposuction can be used safely, which enhances the thoroughness of fat removal and the contraction of the overlying skin. A total of 160 consecutive patients successfully underwent this procedure. Recovery was rapid, and patients returned to full activities within 24 to 48 hours. The skin remained soft, with minimal to no bruising throughout the entire postoperative period. The problems seen with internal ultrasonic liposuction, such as end hits and skin burns, were avoided. The large incisions required for internal ultrasound liposuction were not necessary. Previous models of externally applied ultrasound support current observations of the safety of external ultrasound lipoplasty. Only one small seroma was seen. External ultrasound lipoplasty is a safe, effective, and low-cost method of ultrasound-assisted removal of localized fat and the fat due to moderate obesity. Physician and patient satisfaction is high.
