Ultrasound Evaluation of a Single Treatment With a Temperature Controlled Multi-Frequency Monopolar Radio Frequency Device for the Improvement of Localized Adiposity on the Abdomen and Flanks.

BACKGROUND AND OBJECTIVES: Energy modalities used for fat reduction include cryotherapy, focused and unfocused ultrasound, radiofrequency, and laser. Two devices have been proven to reduce fat layer thickness using ultrasound as measurement after a single treatment. We hypothesized that a novel, high frequency monopolar radiofrequency device could increase the fat temperature enough to reduce its thickness as measured by ultrasound, without excessively increasing the temperature of the skin, leading to a safe, tolerable, and clinically relevant reduction of fat.
