Laser lipolysis: current practices.
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.
