Before the fat is actually suctioned off, fluid is injected into the area of fat to be removed, making liposuction easier to carry out.
A cannula is inserted through a small, 1 to 1.5 cm incision in the skin sited in an existing fold. The cannula is connected via a hose to a vacuum pump.
The cannula is then moved in an arc through the fatty tissue to be aspirated and the excess fat cells are suctioned out.
In ultrasonic liposuction, ultrasound waves are transmitted through the tip of the cannula at a frequency which liquifies the fat before it is suctioned out. Deciding which method is most beneficial in your particular case depends on many factors which your plastic surgeon will discuss with you before the operation.
If your liposuction is carried out under local anaesthetic, you may experience pressure, pulling and vibration during the operation.  The actual removal of the fat should not cause you any pain, even under local anaesthetic. At the end of the procedure, the small incisions in the skin are sutured and, whilst still on the operating table, you will be fitted with a compression corset. Compression bandages are applied for liposuction in the region of the face, breasts or arms.
