and a headrest with piezoelectric crystals to produce energy capable of destroying selectively the fat cells without damaging noble elements as lymphatic and the vessels.This process of destruction is called “cavitation”. Next, the emulsion or liquefaction is aspired at low pressure to reduce the tissue’s trauma and the physical effort of the surgeon.

This technique involves smaller blood loss and minor post-surgery bruise, and allows removing larger fat volumes in just one surgical time, under local anesthesia and trans-operatory monitoring. These are ambulatory surgeries, after a pair of hours the patients return to their houses.

During surgery a liquid is added with local anesthesics to infiltrate the fat cells, this is what is called tumescent technique by Klein. When the adiposities are dilated by this liquid it is easier to destroy them using ultrasonic energy. The blood vessels and nervs are not affected since the cavitation of this energy selectively destroys fat and preserves neighbour structures helping the posterior retraction, and without burning the skin. Additionally, it is safer for the doctor and less aggressive for the organism with less blooding and pain.

Since there exist fewer tissues’ traumatism during surgery, they inflame less, and the recovery and results are faster. However, there is variability between different patients.
