The word “liposuction” was created as a combination of the Greek word “lipos” which means fat and “suction” which, of course, means to suck it out.
To quote from http://www.Liposuction.com- “liposuction is one of the most commonly performed cosmetic surgeries in the United States. In 1974, Dr. Giorgio Fischer, a gynecologist from Italy, invented the original form of liposuction. French physicians Illouz and Fournier further developed liposuction around 1978. By 1980, liposuction was extremely popular in the United States but was confronting negative publicity due to patients experiencing excessive bleeding and undesirable rippling of the skin after surgery.”
“In 1985, Dr. Jeffrey A. Klein, a California Dermatologist, invented the tumescent technique for liposuction which allowed patients to have liposuction performed totally by local anesthesia using much smaller cannulas. ”
“The word “tumescent” means swollen and firm. By injecting a large volume of very dilute lidocaine (local anesthetic) and epinephrine (capillary constrictor) into subcutaneous fat, the targeted tissue becomes swollen and firm, or tumescent.”
Cannulas are the tubes used by insertion into your body through a small incision where fat cells are. Below is a cross-section view of your skin. The fat is in the subcutaneous layer, which is richly supplied with blood vessels.
