Assessing Comparative Utility Measures of Subcutaneous Fat

In reviewing studies of body contouring to date, no single objective technique that is sufficient for quantifying noninvasive fat reduction was found.

lsm-16-0273-alam-editedWausau, WI (February 27, 2018) – Currently available noninvasive fat reduction procedures include cryolipolysis, photobiomodulation, radiofrequency, high-intensity focused ultrasound, and chemical adipocytolysis. Studies support the safety and effectiveness of these procedures, but the variability among the quantitative measurement techniques complicates comparison of outcomes across trials. In a recent review published in Lasers in Surgery and Medicine (LSM), the official journal of the American Society for Laser Medicine and Surgery, Inc. (ASLMS), the most commonly used research methods for quantifying non-invasive fat reduction and assessed 36 studies, each with at least 10 subjects, with varying measurement techniques were described.

The review was conducted by Sogyong L. Auh, MD, PhD; Sanjana Iyengar, MD; Alexandra Weil, BS; Diana Bolotin, MD, PhD; Todd V. Cartee, MD; Jeffrey S. Dover, MD, FRCPC; Ian A. Maher, MD; Joseph F. Sobanko, MD; Joel L. Cohen, MD; Emily Poon, PhD; and Murad Alam, MD, MBA, MSCI. Their manuscript titled, “Quantification of Noninvasive Fat Reduction: A Systematic Review” was selected as Editor’s Choice in the February 2018 issue of LSM.

“Noninvasive fat reduction works, providing clinically and aesthetically significant improvements, but the degree of fat change is difficult to measure precisely,” said Dr. Alam.

There were significant limitations observed in all available methods: photographic comparisons were subjective; circumference or caliper measurements were confounded; ultrasound was operator dependent; MRI was expensive; computed models and simulations were in early development. As new technologies are developed, the need for reliable, accurate and practical measures of subcutaneous fat will increase.

Dr. Murad Alam is professor of dermatology, otolaryngology, and surgery; vice-chair of the department of dermatology; director of the cosmetic dermatology and laser clinic; and chief of the section of cutaneous and aesthetic surgery, at Northwestern University’s Feinberg School of Medicine.

Editor’s Choice is an exclusive article published in LSM, the official journal of the ASLMS. View the complete manuscript.
