Your surgeon will describe the various liposuction techniques available and recommend the most suitable one for you.
cannula is inserted and used to suction away the fat layer that lies deep beneath the skin. Suction is provided by a vacuum pump.
The incision sites will be carefuly chosen so that scarring is as inconspicuous as possible. Naturally fluid is lost along with the fat. To prevent shock, therefore, patients are carefully monitored and given intravenous fluids during and immediately after surgery.
Within the basic technique of liposuction variations have been developed:
- Fluid Injection (the ‘tumescent’ technique)
In this commonly-used technique a medicated solution is initially injected into the fatty area to be suctioned. The preparation – a mixture of intravenous salt solution, lidocaine (a local anaesthetic) and epinephrine (to contract the blood vessels) – assists fat removal, reduces blood loss and provides anaesthesia during and after surgery.
- Fluid injection also helps to reduce the amount of post-operative bruising.With the tumescent technique, a large volume of fluid – sometimes as much as three times the amount of fat to be removed – is injected. Often performed on patients who need only a local anaesthetic, this procedure takes a little longer than traditional liposuction. Additional anaesthesia may not be necessary since the injected fluid already contains it.
- Ultrasound-assisted Lipoplasty (UAL)
For this a special cannula and machine that produce ultrasonic energy is used, the energy breaks down the walls of the fat cells, liquefying the fat which is then removed by standard liposuction.
- UAL improves the ease and effectiveness of liposuction in fibrous areas of the body, such as the upper back or the enlarged male breast. It also offers extra precision as a secondary ‘fine tuning’ procedure once the main volume of fat has been removed by other methods. In general, UAL takes longer than basic liposuction.
