When the liposuction began to take place extensively at the end of the last century, the aspiration cannulae had a very large extraction diameter that allowed to extract large volumes and do it in a short time. However, this generated a bad reputation for this technique because, by using a pressure of "aggressive suction", they left behind asymmetries, subsidence in the skin and, in general, bad results. In all cases of liposuction I use the LMI technique that combines cannulas with a very small caliber with different fat extraction pressures depending on the depth of it.
