Background:
Cryolipolysis received U.S. Food and Drug Administration clearance for reducing fat from the flanks, abdomen, and thighs. The upper arms are an off-label indication for cryolipolysis, and outcome data on reducing fat from the arms using a cryolipolytic device has rarely been published.
Objective:
This pilot study evaluated cryolipolysis to reduce upper arm fat.
Materials And Methods:
A flat vacuum applicator was used to treat seven subjects in a single-side study. The patients underwent one cycle of upper-arm cryolipolysis treatment, and the contralateral arm served as a control. Follow-up was conducted at 8 weeks. Equalization treatments were delivered subsequently to the opposite arm. Efficacy was evaluated by ultrasound imaging, physician's assessment, and patient satisfaction. Side effects and adverse events were monitored.
Results:
Ultrasound measurements showed a decrease in the fat layer at 83.3% of the 12 measured sites. The mean reduction in fat layer thickness was 15.3%, corresponding to 2.03 mm. A significant difference was detected between baseline and 8-week assessments (p = 0.001).
Conclusion:
One treatment using a flat vacuum cryolipolysis applicator was safe and effective to reduce arm fat.
