“…Third, the high laser energy delivered in continuous mode, besides rupturing the adipocytes, coagulates collagen fibers together with small vessels [20,21]. As a consequence, surgical injury and bleeding are drastically reduced without changing the hemodynamics [22][23][24]. Fourth, the process of tissue retraction and skin tightening is rather slow and should not be assessed until 2 months after surgery.…”

Laser-assisted lipolysis in the treatment of gynecomastia: a prospective study in 28 patients

Gynecomastia is the most common breast pathology. Numerous excisions and liposuction techniques have been described to correct bilateral male breast enlargement. Recently, there has been a shift from the open approach to minimally invasive techniques. This article reports a 5-year experience using laser-assisted lipolysis (LAL) to treat gynecomastia, and describes the surgical technique. Between January 2006 and December 2010, a total of 28 patients with bilateral gynecomastia were treated with LAL. Patients had a mean age of 36.5 years (range 24 to 56 years). LAL was performed with a 980-nm diode laser (continuous emission, 15 W power, 8-12 kJ total energy per breast) after tumescent anesthetic infiltration. The breast was evaluated objectively by two physicians who compared chest circumference and photographs. Patients were also asked to score the results using a visual analogue scale: 75 to 100 (very good), 50-74 (good), 25 to 49 (fair) and 0 to 24 (poor). The postoperative period for all patients was incident-free. After 6 months, 18 patients (64.3%) scored the results as "very good", 6 as "good" (21.4%), 3 as "fair" (10.7%) and 1 "poor" (3.6%). Mean chest circumferences pre- and postoperatively were, respectively, 117.4 ± 11.1 cm and 103.3 ± 7.5 cm (p < 0.001), corresponding to a mean difference of 14.1 cm. Physicians scored the photographs as "very good" in 22 patients (78.6%), as "good" in five patients (17.9%), and as "fair" in one patient (3.6%). LAL in gynecomastia is safe and produces significant effects on fatty tissue, with a reduction in breast volume, together with significant skin tightening. Provided an appropriate amount of energy is delivered by an experienced operator, the results are both significant and consistent.

“…They concluded that serum cholesterol and triglyceride levels remained in the normal range after laser lipolysis. They proposed two hypotheses: fat elimination is so gradual that an increase in circulating lipid levels is not measurable and/or the damaged adipocytes are undergoing apoptosis and being removed by phagocytosis, presumably via activated macrophages [41].…”

Laser liposuction was initially developed as a technique for laser lipolysis. In 1992, Apfelberg was the first to describe the direct action of laser in the adipose tissue. Initially, the technique was developed only for lipolysis of unwanted fat in a small region without suction of dissolved fat. Later, it evolved as laser-assisted liposuction, which is a technique that combines adipocyte disruption with laser beam and suction of the dissolved fat from the treated area with different types of cannulas. The neodymiumdoped yttrium aluminum garnet (Nd:YAG) 1064 nm has been introduced as first laser for lipolysis. Blugerman, Schavelzon, and Goldman introduced the concept of the pulsed 1064-nm Nd:YAG system for laser lipolysis. They proved the effect of the laser energy on fatty tissue as well as the on surrounding tissues (dermis, vasculature, apocrine, and eccrine gland). After tissue damage with photo-optical thermal energy, the following histological changes have been noted: (1) adipocyte cells have been disrupted, (2) blood vessels have been coagulated, (3) new collagen has been induced. All those histological changes induce better clinical outcome such as less ecchymosis, less bleeding, smoother, and firmer skin as result of new collagen formation followed by skin retraction. Laser liposuction was developed as a minimally invasive liposuction technique, where energy breaks adipocytes (comparing with traditional liposuction, in which disruption is manual). Wave length of 1064 nm has hemoglobin as a target for its photo-optical energy, and new wave length of 1470 nm has water molecules (H 2 O) as a target. Infiltration of the Klein's solution helps laser to dissolving of fatty tissue faster and more energy to accumulate, followed by new collagen formation. Laser-assisted liposuction in all types of lipodystrophies and cellulite can be successfully applied. High definition of the body is a result of the energy as well as the technique of liposuction. Laser liposuction can be applied on the face for fat removal and as a part of face lifting or better to say endolight lifting. Today, we have lot of companies that have developed different liposuction lasers (Nd:YAG; diode) with different wave lengths.

Laser-assisted liposuction (LAL) is a recent innovation within the field of liposculpture. In addition to body contouring, the indications of LAL are skin retraction in areas of flaccidity and fat melting for challenging surgical cases including revisions, areas of dense fibrosity, and large-volume cases. A photothermal effect explains the effects of LAL on tissue, regardless of the wavelength used. Advantages of LAL include reduced bruising, edema, pain, and recovery time. Disadvantages are most often related to thermal effects on tissue, such as skin blistering. Currently, 3 wavelengths, 980, 1064, and 1320 nm, are Food and Drug Administration-approved for LAL. Comparative studies examining the safety and efficacy of LAL have appeared in the medical literature. Technical considerations, emerging technology, and future indications are important to the success and continued development of this procedure.
