Laser Lipolysis Using a 1064/1319-nm Blended Wavelength Laser and Internal Temperature Monitoring

Marc J. Salzman, MD, FACS

Lasers, both in single and multiple wavelength designs, have recently been introduced to
enhance the results of liposuction. Safe parameters of fluence and temperature have not
yet been described. In this study, I describe a series of laser lipolysis patients treated with
a dual wavelength (1064/1319 nm) laser where internal and external temperatures have
been measured. From this series of 36 patients treated with a 1064/1319-nm wavelength
laser for laser lipolysis, we calculated the specific heat of the fat and tumescent fluid
combination to be 4.7 J/(g°C). The average increase in temperature measured in the
subcutaneous space was 16°C.

Laser Lipolysis: Current Practices

Melanie D. Palm, MD | Mitchel P. Goldman, MD

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.

Noninvasive Radio Frequency for Skin Tightening and Body Contouring

Robert A Weiss, MD, FAAD, FACPh

The medical use of radio frequency (RF) is based on an oscillating electrical current forcing collisions between charged molecules and ions, which are then transformed into heat. RF heating occurs irrespective of chromophore or skin type and is not dependent on selective photothermolysis. RF can be delivered using monopolar, bipolar, and unipolar devices, and each method has theoretical limits of depth penetration. A variant of bipolar delivery is fractional RF delivery. In monopolar configurations, RF will penetrate deeply and return via a grounding electrode. Multiple devices are available and are detailed later in the text. RF thermal stimulation is believed to result in a microinflammatory process that promotes new collagen. By manipulating skin cooling, RF can also be used for heating and reduction of fat. Currently, the most common uses of RF-based devices are to noninvasively manage and treat skin tightening of lax skin (including sagging jowls, abdomen, thighs, and arms), as well as wrinkle reduction, cellulite improvement, and body contouring.

Regional Anesthesia for Aesthetic Surgery

John Bramhall

WHAT WE NOW refer to as aesthetic or cosmetic surgery was not commonly practiced until the advent of effective, reliable, and safe anesthetic techniques.
