“…2 Typically, the laser lipolysis procedure is conducted using a 300-or 600-μm optical fiber with a flat tip (i.e., end-firing), delivered through a 1-mm cannula. 9 During the laser lipolysis, the interstitial temperature is normally maintained between 38°C and 45°C to ensure safety of the procedure and to achieve favorable clinical outcomes, including neocollagenesis and skin tightening. 7,8 After inserting the cannula through the skin, plastic surgeons begin to move the optical fiber back and forth in the upper part of the adipose layer in order to melt fat.…”

“…2 However, high irradiance from the fiber tip, direct tissue contact, and slow fiber movements often cause temperature increase higher than 65°C. 2,9,13 Initially, the wavelength of 1064 nm was used for clinical lipolysis due to deep optical penetration in tissue. 11,12 A number of clinical studies have evaluated various wavelengths for laser lipolysis, including 980, 1064, and 1320 nm.…”

Laser-assisted lipolysis has been implemented to reduce body fat in light of thermal interactions with adipose tissue. However, using a flat fiber with high irradiance often needs rapid cannula movements and even undesirable thermal injury due to direct tissue contact. The aim of the current study was to explore the feasibility of a radially diffusing optical applicator to liquefy the adipose tissue for effective laser lipolysis. The proposed diffuser was evaluated with a flat fiber in terms of temperature elevation and tissue liquefaction after laser lipolysis with a 980-nm wavelength. Given the same power (20 W), the diffusing applicator generated a 30% slower temperature increase with a 25% lower maximum temperature (84±3.2°C in 1 min; p<0.001) in the tissue, compared with the flat fiber. Under the equivalent temperature development, the diffuser induced up to fivefold larger area of the adipose liquefaction due to radial light emission than the flat fiber. Ex vivo tissue tests for 5-min irradiation demonstrated that the diffuser (1.24±0.15 g) liquefied 66% more adipose tissue than the flat fiber (0.75±0.05 g). The proposed diffusing applicator can be a feasible therapeutic device for laser lipolysis due to low temperature development and wide coverage of thermal treatment.
