A surgeon inserts a long thin tube called a cannula and manually breaks fat cells down by rotating and moving the cannula forward and backward. Then, fat is sucked out. Tumescent liposuction is the most popular variation of traditional liposuction. Prior to manipulation with the cannula, a surgeon introduces anesthetic-containing fluid into the target area. The fluid minimizes blood loss and simplifies fat extraction.
A surgeon utilizes a special type of cannula that when inserted produces ultrasound energy to liquify fat tissue. It allows to suction fat more easily. Ultrasound-assisted liposuction (UAL) has become well-known under the brand name VASER® Liposuction.
Similar to ultrasound liposuction, a surgeon applies laser energy to melt fat tissue. Additionally to fat removal, laser-assisted liposuction (LAL) is capable to tighten skin with heat coming out from the laser devise. Smartlipo® is the most famous brand producing laser liposuction equipment.
A powered cannula replaces a manual one to quickly break down fat deposits and suck them out. Power-assisted liposuction (PAL) removes fat more efficiently and has a shorter procedure time resulting in quicker patient recovery.
