Tumescent liposuction is a popular liposuction technique in which fluid is injected into the target area to create space between the muscles and fatty tissue. This causes the tissue to become swollen and firm (tumescent), loosening the fat cells, reducing bruising, and allowing the surgeon more room to perform the movements that loosen the fat cells before they are suctioned out of the body.
Ultrasonic liposuction is a procedure used by surgeons to remove fat from the body. Ultrasonic energy is converted into vibrations and heat, and then delivered through paddles and metal rods either into the body or over the skin. There are two types of ultrasonic liposuction, external and internal.
With internal ultrasonic liposuction, a special tumescent fluid is delivered into the fatty area by means of a hollow cannula. The cannula is similar to a large hollow needle, through which flow the ultrasonic vibrations, heat, and tumescent fluid. The ultrasonic energy breaks down the fat into oil, which is mixed with the tumescent fluid. The converted fat that has mixed with the tumescent fluid is sucked out through the cannula with the help of a suction vacuum.
External ultrasonic liposuction is a method of delivering the ultrasonic energy to fat without breaking or piercing the skin. The energy is delivered via metal paddles that are placed over the skin, with the vibrations breaking down the fat externally. The trouble with external ultrasonic liposuction is that most scientific research shows that it has no benefit whatsoever in the removal of fat. Because of these findings, external ultrasonic liposuction is rarely used these days. |
