Tumescent liposuction. A local anesthetic is used to numb the area of your body where the tube will be inserted. Next, a large amount of an tumescent solution containing lidocaine and epinephrine is injected into the fatty tissue before traditional liposuction is done. Tumescent liposuction may not require general anesthesia (which makes you sleep through the procedure).

Before incorporating fluid injection into the liposuction treatment, fat extraction was performed “dry.” Without the extra fluid to help break up and emulsify fat cells, the process was more painful and the extent of treatment was more limited. During tumescent liposuction, the medicated solution is injected before the removal process begins, reducing discomfort and bruising and allowing a greater amount of fat removal.

Ultrasound-assisted liposuction. This technique uses ultrasound to liquefy the fat, which makes it easier to remove. This technique may be particularly helpful in removing fat from the neck, upper abdomen, sides, and back but is less in use.

Laser-assisted liposuction. This technique uses low-energy waves to liquefy the fat, which is removed through a small cannula.
