The sound waves are able to modify the organizational structure when they are transmitted through fluids. On the basis of this concept was used for the first time, ultrasound, in cataract surgery in the mid-1960s, with the introduction of the phacoemulsification. This is how its use is has spread to various branches of surgery when the goal has been the selective destruction of unwanted tissues. The Italian physician, Michele Zocchi in 1988, was the first plastic surgeon who applied the ultrasonic waves to selectively destroy fat cells of the body, its formidable results have encouraged investigations around the world which continue, hence its technology and know-how to suffer transformations and new concepts and directions appear. To make a sound wave, which is mechanical energy, ultrasonic is necessary that its frequency is above 16000 kHz, in plastic surgery this is generated from crystals that possess the ability to piezoelectric or are able to deform with AC power, these fluctuations of deformation produced vibrations at ultrasonic frequency the same as amplified it channeled them is through a cannula inserted between fat cells destabilize them causing rupture of their cell membrane, releasing its contents, the same that sucks it at low pressure through a cannula. Thus ultrasound is used to sculpt the body.
The best candidates for liposuction assisted with ultrasound (LAU) are the same for liposculpture assisted by suction (SAL), which are patients with normal weight, elastic skin and fat accumulation that do not disappear with nor with the gym or with diets. Choosing the ideal method to perform liposuction depends on the experiences and training of the surgeon, both techniques both the assisted by suction salt (conventional) as the assisted by ultrasound LAU possess advantages some above others and specific indications that to some extent make them complementary, ultimately your surgeon will choose the most suitable for your particular case. On the other hand liposculpture not recommended it to patients with systemic, cardiac, pulmonary disease, diabetes, and degenerative diseases. The specific complication by the use of ultrasound is the local skin burn, complication that avoided if the plastic surgeon is well trained in its use. Finally, liposculpture is a simple surgical procedure, aimed at patients who have decided to change his lifestyle one more healthy and disciplined hence need to exist the, prior commitment, on the part of the patient care results performing exercises and diet.
