There is great confusion among the public and surgeons, for that matter, about the differences in the liposuction techniques. All three techniques involve removing fat through a liposuction device. Smartlipo and Smartlipo MPX uses a pretreatment with a laser to perform lipolysis (breaking up of the fat). This is then followed by traditional liposuction to remove the fat. The name is really as misnomer since the Smartlipo is just the lipolysis portion and not really the liposuction portion. Ultrasound liposuction uses a pretreatment with ultrasound technology to break up the fat. This is then followed by traditional liposuction to remove the fat. Again, it is a misnomer, since the ultrasound is not doing liposuction, it is doing lipolysis. Traditional liposuction skips the pre-treatment steps in Smartlipo and Ultrasound, and just starts taking out fat through mechanical force. This is either by the brute force of the surgeon or with Power-Assisted Liposuction (PAL) which vibrates the liposuction cannula to break up the fat while it is sucking it out. The attraction of Smartlipo is that is can be performed with smaller incisions than traditional liposuction since the fat is broken up by the laser. It is generally also performed under local anesthesia and has a quicker recovery with less bruising. So, as soon as the procedure is over, you are basically ready to go. The advantage of ultrasound lipo is a great ability to break up tissue. This is good for areas like the gynecomastia in the breast with thick and fibrous tissue. The advantage to traditional and PAL liposuction is that great volumes of fat can be taken out since you are asleep and cannot feel anything. This is also usually performed in a hospital where you have monitoring which is necessary when large volumes of fat are removed.
All of the techniques are also dependent on the skills of the surgeon. Not all barbers are the same, not all chefs are the same, not all tailors are the same. Likewise, not all surgeons are the same.
I hope this is helpful. Good luck with your procedure.
