The intervention is done by special metal cannulas which are placed inside the body through small incisions between 3 and 4 mm. Cannulas are connected with the source of negative pressure. The history of liposuction dates back to 1920s when the French surgeon Charles Dujarier was the first to remove fat tissue by curettage (scraping). By addition of negative pressure Italian gynaecologists Arpad and Giorgio Fischer in 1974 removed fat tissue by special blunt cannulas rounded at the tip with the help of negative pressure. They were followed by French surgeons Pierre Fournier (known for the dry technique – without the infiltration of liquid) and Yves Gerard Illouz (invented the infiltration by hypotonic liquid – wet technique). An even greater expansion of this method in the world occurred after the invention of local tumescent anaesthesia by the Californian dermatologist Jeffrey A. Klein.

A vacuum device serves as a source of negative pressure, and for small scale liposuctions the negative pressure is created in a suctioning syringe which is connected to the cannula (syringes lipoplasty). This approach enables, in demanding liposuctions, a greater manual mobility of the surgeon, because there is no plastic tube which connects the cannula to the vacuum device, reducing thereby the possibility of manipulation of the cannula. In the very beginnings of liposuction as a surgical technique for the removal of excess fat tissue, the suction was done without special preparation. This used to be called “dry” liposuction. The development of this technique led to hydroliposuction. This technique includes the injection of special solution into the fat tissue in order to break it down. The result is that the vacuum doesn’t tear off pieces of fat tissue, but a dense yellow mass is being aspirated. Thanks to special drugs combined with this liquid, the bleeding was reduced, as well as postoperative pain. A further step was the use of ultrasound prior to the surgical breaking of the  fat tissue, and in recent times liposuction is done with “pneumatic” cannulas which, as they move through the tissue, cause vibrations. Instead of ultrasound, medical fibers laser is nowadays more in use for medical fibers laser lipolysis of fat tissue (Laser Assisted Lipoplasty).
