“…However, credible studies comparing its advantages, protective features and effectiveness to those of the well-established technique of conventional liposuction are lacking. Five studies [40][41][42][43][44] indicated that LAL has advantages over conventional liposuction, and only two [45,46] failed to find statistically significant differences between the techniques in the evaluated endpoints. Histological review [40,42] shows that subcutaneous fat reduction [41,43], skin retraction [41][42][43] and patient satisfaction [41,43] were the key endpoints assessed in the studies.…”

“…Two studies [41,43] found that the LAL technique produced superior results in terms of subcutaneous fat reduction as measured by ultrasound analysis after the procedure. The use of a laser could potentially aid in the destruction of adipocyte membranes, making removal simpler and more uniform, as well as improving the clotting of tiny blood vessels and lymphatic vases.…”

Enhanced Liposuction - New Perspectives and Techniques

Liposuction as the word suggests involves sucking out fat from the subcutaneous layers. In many parts of the world it is used interchangeably with weight loss and non-surgical fat reduction procedures. The gold standard for liposuction for many decades has been the “Suction assisted Liposuction’ also called SAL. Newer technologies have been introduced with varied claims about skin retraction, painless and complete evacuation of fat as well as a faster recovery. This chapter elaborates the personal experience of the Authors with regards to the discussed newer technologies bringing into perspective their indications, mechanism of action as well as clinical outcomes. At the outset the Authors would like to state emphatically that technologies are as good as the surgeon holding them and that somewhat same result can be achieved through a traditional liposuction in most of the cases. A surgeon looking to incorporate these technologies in practice should first achieve a mastery of traditional SAL for the best outcomes.

Introduction Laser lipolysis is a rapidly growing noninvasive body-contouring treatment in Asians. There is increasing demand for leg contouring, especially in areas where unwanted fat deposits are prominent despite diet and exercise. Medial fat knees are one of the esthetic concerns of women today and can be a challenging problem in terms of treatment. There are few noninvasive options to remove fat from these areas. This study aims to evaluate the safety and efficacy of a 1060-nm diode laser for medial knee fat reduction. Methods Nineteen subjects with localized unwanted fat on the medial knees were enrolled into this study. All of them were treated with a single session of 1060-nm diode laser at a power setting of 1.0–1.4 W/cm 2 , depending on patient tolerance. Body weight, knee circumference at 3 cm above the medial epicondyle of the femur, and knee fat thickness measured by ultrasonography were recorded at baseline and 1, 3, and 6 months after treatment. Clinical photographs and ultrasound images were taken before and after treatment. Side effects were documented during follow-up visits. Subjects answered a satisfaction questionnaire at the completion of the study. Results All subjects were female, with mean age of 32.3 ± 5.3 years and body weight of 59.8 ± 11.6 kg. The average power setting was 1.3 ± 0.1 W/cm 2 with pain score of 6.1 ± 1.0. Significant reduction in knee circumferences ( p < 0.001) at 1-, 3-, and 6-month follow-up visits compared with baseline, and knee fat thickness measured by ultrasound in both axial and sagittal plane at 1 and 6 months after treatment ( p = 0.036 and p < 0.001, respectively) were recorded. Side effects were mild and transient, including mild erythema and tenderness. Conclusion The 1060-nm diode laser is effective and safe for knee circumference and medial knee fat layer thickness reduction. Trial registration ClinicalTrials.gov identifier, TCTR20220219002.

“…The diode lasers emitting at 975–980 nm have not been widely accepted in clinical practice. However, several reports explored their possible applications in otorhinolaryngology , oral surgery , surgery , treatment of benign prostatic hyperplasia , invasive laser lipolysis , and endovenous laser treatment of saphenous veins . For example, it was reported that a 980 nm diode laser with a pulse duration of 10 ms was successfully used to treat 300 patients with different skin disorders, including vascular lesions, cysts and pseudocysts, infectious diseases, and malignant tumors .…”

Temperature Depth Profiles Induced in Human Skin In Vivo Using Pulsed 975 nm Irradiation

et al. 2019

Background and Objectives The aim of this study was to determine the temperature depth profiles induced in human skin in vivo by using a pulsed 975 nm diode laser (with 5 ms pulse duration) and compare them with those induced by the more common 532 nm (KTP) and 1,064 nm (Nd:YAG) lasers. Quantitative assessment of the energy deposition characteristics in human skin at 975 nm should help design of safe and effective treatment protocols when using such lasers. Study Design/Materials and Methods Temperature depth profiles induced in the human skin by the three lasers were determined using pulsed photothermal radiometry (PPTR). This technique involves time‐resolved measurement of mid‐infrared emission from the irradiated test site and reconstruction of the laser‐induced temperature profiles using an earlier developed optimization algorithm. Measurements were performed on volar sides of the forearms in seven volunteers with healthy skin. At irradiation spot diameters of 3–4 mm, the radiant exposures were 0.24, 0.36, and 5.7 J/cm2 for the 975, 532, and 1,064 nm lasers, respectively. Results Upon normalization to the same radiant exposure of 1 J/cm 2, the assessed maximum temperature rise in the epidermis averaged 0.8 °C for the 975 nm laser, 7.4 °C for the 532 nm, and 0.6 °C for the 1,064 nm laser. The characteristic subsurface depth to which 50% of the absorbed laser energy was deposited was on average 0.31 mm at 975 nm irradiation, and slightly deeper at 1,064 nm, and 0.15 mm at 532 nm. The experimentally obtained relations were reproduced in a dedicated numerical simulation. Conclusions The assessed energy deposition characteristics show that the pulsed 975 nm diode laser is very suitable for controlled heating of the upper dermis as required, for example, for nonablative skin rejuvenation. The risks of nonselective overheating of the epidermis and subcutis are significantly reduced in comparison with irradiation at 532 and 1,064 nm, respectively. Lasers Surg.
