Until the Tickle Liposuction unit, the best method for liposuction was the traditional liposuction for the following reasons: Energy source, such as laser, radiowave, ultrasonic, added a new diminsion of complications because of the heat from the cannula. I have seen article after article of burns from such liposuction equipment. Of course, in the proper, skilled hands such complications are more rare.
Another disadvantage of laser or other energy sourced liposuction is the increase time it takes to perform the procedure. They are two step procedures in that first you must melt the fat, and then go back and liposuction the melted fat out.
The Tickle Lipo, contrary to what some think is not an ultrasonic energy source liposuction unit. There is minimal to no heat as it is subsonic. The true name is Nutational Infrasonic Liposuction (NIL).
Now for the NIL advantages: The specific rotational movement actually only breaks down the fat and not the connective tissues. This procedure shortens the procedure by 25% or more, and because of its lack of damage to surrounding tissues, results in less bruising, swelling, and recovery time. The Vibration-like activity of the cannula tip reduces the pain during and after the procedure. General anesthesia is rarely needed.
An additional benefit is that, unlike laser,etc., it does not harm the Adipose Derived Regenerative Cells (ADRC), and if fat transfer is desired for volumizing the breast, face, hands or buttocks, the fat is more likely to survive, even more so that traditional liposuction.
With all of the above said, the most important factor is still the skill and experience of the surgeon.
For local anesthesia, the tumescent technique is still necessary regardless of the equipment.
