**4.2 Traditional liposuction**

• In the traditional suction-assisted liposuction (SAL) method, the liposuction process is performed by suctioning the deep fatty tissues with a vacuum driven source providing negative pressure [8, 9]. This method is usually carried out with a device that provides negative pressure with aspiration [10]. Ultrasoundassisted liposuction (UAL) is another technique available. UAL may cause a higher rate of seroma formation compared to the traditional (SAL) method. Furthermore, care should be taken to avoid thermal injuries that may occur due to its thermal effect. SAL can be combined with power-assisted liposuction (PAL). A forward moving cannula is used in the power-assisted liposuction (PAL) method. This method can be preferred for patients who have dense soft tissues or secondary cases. One of the greatest advantages is that the surgeon gives less effort and provides suction in more dense areas of fibrous tissue. In laser-assisted liposuction (LAL) method, it is estimated that the laser energy

causes the destruction of fatty tissue. One of the most advantage of LAL is its capability for a better skin retraction compared to the traditional method. This is a great value for patients with severe skin laxity. LAL is our preferred method for arm liposuction for this high potential skin contraction feature. Radiofrequency-assisted liposuction (RFAL) method can also be preferred in patients with severe skin laxity to provide a skin contraction and retraction. Care should be taken against thermal injuries that may occur on the skin due to thermal energy during the radiofrequency-assisted liposuction (RFAL) process.
