Summary: The concept of power-assisted liposuction (PAL) offers a happy medium between traditional liposuction and more recent technologies such as ultrasound-assisted liposuction. Physicians appreciate that their patients’ results remain more dependent upon technical skill rather than gadgetry, while patients enjoy a shorter procedure time that typically also offers a faster recovery period. In short, there are a number of benefits to consider with regards to PAL.
The Mechanism Behind PAL
Liposuction has consistently ranked among the most often performed cosmetic surgery procedures around the world. The process of making tiny incisions as access points for fat removal via suction has proved an ideal solution to the problem of isolated pockets of adipose tissue that remain resistant to dietary changes or exercise routines.
At the same time, traditional liposuction is undeniably invasive and often physically fatiguing for the surgeon to perform; the process of dislodging the fat cells from the adjacent connective tissue takes a significant amount of manual effort. In tumescent lipo, this is accomplished with a vigorous back-and-forth motion of the cannula itself. In power-assisted liposuction, however, a reciprocating cannula is used instead.
The adjustable settings of this mechanized action allows the physician to work according to his or her speed preference, adapting as needed for greater precision, while the vibrating motion more efficiently breaks apart fatty deposits compared to manual efforts. Far more fat can be removed using PAL in a shorter amount of time than with traditional lipo during a longer surgery. This greater efficiency during surgery also means a reduction in trauma to surrounding blood vessels and tissues throughout the procedure, which in turn means less discomfort and bruising during recovery.
Is PAL the Best Liposuction Option?
Proponents of PAL claim that the power cannula offers the best liposuction results, while traditionalists say the results don’t offer any major improvements compared to traditional lipo. Which argument is the more accurate of the two?
Even researchers seem to be divided at times. A 1999 study on power liposuction concluded that, while PAL was definitely superior in terms of facilitating fat extraction, the recovery rates of patients were not faster, and the end results were equivalent to more traditional methods. However, a 2001 study comparing power lipo to traditional showed several clear benefits of the former:
- Procedure times with PAL were shorter.
- Surgeon fatigue was reduced when using a reciprocating cannula.
- A greater amount of fat was aspirated per minute compared to traditional liposuction.
- Intraoperative and postoperative pain were both reduced.
- Patients saw a reduction in postoperative edema and ecchymosis.
- Patients indicated higher rates of satisfaction with the results of their procedure.
The 2001 study added that reduced surgeon fatigue contributed to greater precision as well as improved patient safety.
The Tool vs. The Surgeon
Regardless of the objective data on power-assisted liposuction as a positive alternative to traditional lipo, the bottom line remains the same: while there are some definitive advantages to incorporating a vibrating cannula during surgery, the method itself is not enough on its own to magically deliver superior results. In PAL, as with all forms of body contouring, the skill of the physician is integral to ensuring a positive outcome.
However, when all other factors are equal, a highly qualified and experienced physician who is already adept at body contouring via liposuction is likely to enjoy a higher level of finesse during surgery when using PAL, while the patient sees different benefits during recovery and also in the final body contours.
