Power-Assisted Liposuction – The procedure for power-assisted liposuction is generally the same as described for conventional liposuction in the preceding paragraphs. The only difference is that the cannula or surgical instrument used has an oscillating tip that rapidly moves back and forth that aids in the suction of fat in areas where there is more fibrous tissue. These areas include the back, “love handles,” and the male breast. The surgeon will often use a combination of power-assisted and conventional cannulae to achieve the desired aesthetic result. Power assisted liposuction appears to achieve the same stated advantages of ultrasonic liposuction at a lower cost and without the same increase in risk.

Laser Lipolysis – There are three types of devices currently approved by the FDA for laser liposuction. Laser liposuction uses the energy of a laser in an effort to break up the fat less traumatically. The other goal of laser liposuction is to modulate the overlying skin envelope and tighten the skin in order to create a tighter, smoother look. There are many trade names associated with the laser liposuction devices. For example, CoolLipo is associated with a laser liposuction machine which operates at 1320 nm. This is an intriguing wavelength for laser assisted liposuction because there has been much experience with that particular wavelength in treating the skin. The slim-lipo is another laser lipolysis device that operates at 920. This may prove to be a particularly ideal wavelength for laser lipolysis because fat has a peak absorption of light at that wavelength.

Laser liposuction may function as a stand alone procedure or as an aid to conventional liposuction. Theoretically, because the laser light aids in breaking up and liquefying the fatty tissue so that it is easier to remove, there is less trauma to the tissue. In addition, the laser light and heat generated may also aid in hemostasis so that there is less bleeding and bruising. In addition, the laser energy may help in tightening of the skin as well. This procedure is amenable to being performed under a local anesthesia without sedation, may not require wearing a compression garment for a lengthy period of time, and with time may prove to be suitable and less invasive for patients seeking minimal neck lift surgery.
