Ultrasonic liposuction is a type of fat loss procedure that liquefies fat cells before their removal this is done with the guidance of an ultrasound combined with ultrasonic waves to target fat . Ultrasound assisted liposuction uses a special cannula that vibrates very rapidly and gives off ultrasound energy as the cannula passes through the fat cells that energy liquefies the fat cells which are then suctioned out the ultrasound can be administered either above the skin with a special emitter or below the surface of the skin with an ultrasound cannula. Ultrasound assisted liposuction one of the many variations of liposuction is ultrasound assisted liposuction ual in this technique the vibrations of the ultrasound energy are used to break the walls of the fat cells which cause them to liquefy in turn this makes it much easier for a surgeon to remove the fat. Ultrasonic assisted liposuction ual requires the use of a large volume of tumescent fluid and uses either a metal probe or metal paddle to deliver ultrasonic energy and heat into subcutaneous fat internal ual is the term used to describe the technique where a long metal probe which may be solid or hollow is inserted into fat through a large incision
