Laser lipolysis has fewer trau­mas as well as less bleeding

Liposuction nowadays is the most popular way of weight loss and body contouring. It is a mechanical procedure to reduce fat through the back-and-forth movement of a heavy metal called cannula. The thick cannula, essential for efficient fat removal and subsequent suctioning, causes some undesirable effects such as bruise, scars, heavy blood loss, skin laxity and long-run recovery. While, the new method of liposuction using a 100-300 μm fiber laser inserted into a thin cannula of 1 mm diameter causes less distress and bleeding. Simultaneous interaction between laser radiation and tissue causes faster skin tightening and coagulation of small blood vessels.

Using lasers as complementary tools in liposuction is a novel method. It first introduced in 1994 which is now among the most popular cosmetic surgeries. Common problems with traditional methods - some even with side effects - have made it necessary to choose safer pro­cedures and it appears that laser lipolysis can meet these increasingly important demands. Lipolysis is a 100-600 μm fiber laser inserted into a thin cannula of 1 mm diam­eter, which not only create smaller incisions but also is less traumatic. In comparison with old methods, in the new procedures the coagulation of small blood vessels and skin retraction result from the interaction of laser ra­diation with tissue, causing less bleeding and faster skin tightening. Using lasers as auxiliary devices in lipol­ysis has limited the use of traditional liposuction meth­ods. In this new method, lasers are utilized to produce the desired damages and effects on the tissue. Interaction of laser with tissue cells can have many effects, most of which improve the downsides of the conventional meth­ods. Safety and efficacy of conventional liposuctions have also been enhanced for the new ones by using thinner cannulas, which not only make smaller incisions but also increase the coagulation process of small blood vessels through interaction between laser and tissues. Laser li­polysis also results in selective tissue heating leading to have less thermal damages to target tissues. Such interac­tion also promotes hemostasis, injury healing and post­operative recovery.

Laser lipolysis has a wavelength-dependent mechanism. First, laser radiation is absorbed by fat cells and receptive chromophores, the absorbed radiation then transforms into heat and produces the desired thermal effects. Heat acts on fat cells and extracellular matrix to compensate both reversible and irreversible damages, which also fa­cilitate the process of liposuction by having fewer trau­mas as well as less bleeding. The absorption of radiation in tissue depends strongly on absorption coefficient.

Laser lipolysis is a new technique which is still under development. It indemnifies the conventional liposuc­tion methods concerning tissue damaging and hemosta­sis effects. Notably, the efficacy of laser lipolysis depends on the interaction between laser and tissue. In addition, understanding its mechanism has a vital role in choos­ing suitable laser wavelengths and energy doses. In laser lipolysis, one can evaluate the thermal effects and dam­ages on tissue as well as the required energy dose for achieving desirable outcome by numerical simulation of laser-tissue interaction and that is one of many advan­tages of this method over the traditional liposuction. It is worth mentioning that simulation of laser-tissue inter­action provides enormous research opportunities for the researches in this field.

Laser lipolysis has a purely wavelength-dependent na­ture. Penetration depth of the radiation into tissue is di­rectly proportional to radiation wavelength. Tissue heat­ing also depends on radiation power and the duration laser radiation used. Ab­sorption and scattering coefficient were the key factors in laser lipolysis, since they determined the penetration depth of laser radiations inside the tissue.

Due to the penetration of ra­diation to dermal layers and initiation of collagen gel retraction (CGR). The 1210nm laser is one of the most important features of laser lipolysis causing skin retraction which leads to the decrease in skin laxity following fat removal operations.

A 980-nm-wavelength diode laser equipment was used in all treatments. A 2-mm-diameter rigid cannula with a 600-µm optical fiber was used to transfer energy to the tissues. For body treatment, power was maintained between 18 and 22 W, except in the submental region, inner arms, andthighs, where 14 to 16 W is used.

CHERYLAS 15 watts 1210nm wavelength has absorption-affinity for Lipid-Rich Tissue and has demonstrated to stimulate adipocytes and mesenchymal cells of the subcutaneous tissue, with a new concept: Selective Photothermostimulation (SPS). The application in Liposuction of this wavelength is determined by its preservation of the integrity of adipocytes, making possible the use of these materials for fat grafting in Liposculpture, Breast Reconstruction or as filler in Face Rejuvenation, proven that this technique is less traumatic.
