**4.3 Selection of liposuction cannulas**

• Cannula options are available in various lengths from 2 mm to 4 mm depending on the amount of fatty tissue in the area to be applied during the liposuction procedure. Cannulas which are small in diameter are used to eliminate surface irregularities and minimize the risk of contour deformity. Care should be taken not to loose the skin tissue during liposuction procedure. Hence, the risk of contour deformity can be minimized by directing the sucking holes apart from the skin surface. Arm shaping procedure with the LAL method, begins with infiltration through two stab incisions near the elbow area. These two stab incisions are desired to be located on the posterior half of the arm and to be at a certain distance from each other to allow criscros. Although cris-cros is aimed, it is mainly planned to aspirate regional fat accumulation located along the vertical axis of the arm. In other words, during liposuction, fat aspiration is requested in a single direction, not homogenous and versatile as in abdominal or back region. As the initial step, the process starts as traditional SAL and after the targeted area is aspirated, the laser component is applied alone. According to the tissue elasticity, laser component is applied in certain watts (Orbeam Diode Laser, in a 60-watt laser device, 1000 nm fiber with a 25-watt output and 4500–6500 joules preferred per one arm.).
