Cryolipolysis for Noninvasive Contouring of the Periumbilical Abdomen With a Nonvacuum Conformable-Surface Applicator

BACKGROUND Although most cryolipolysis treatments are performed with vacuum applicators, some patients may have areas of fibrous, nonpinchable fat or find vacuum suction to be uncomfortable. OBJECTIVE This study evaluates a nonvacuum conformable-surface applicator for cryolipolysis of the periumbilical abdomen. METHODS/MATERIALS Twenty subjects with periumbilical subcutaneous fat were treated with a nonvacuum cryolipolysis applicator in this prospective, single-center, open-label clinical trial. Each subject underwent a single treatment cycle with an optional second treatment 10 weeks later. Efficacy was evaluated by blinded review of digital photographs. Subject satisfaction was assessed at 10-week follow-up. RESULTS Twenty subjects completed one treatment, of which 6 underwent the optional retreatment. Independent review demonstrated 77% correct identification of baseline photographs after one treatment, which improved to 100% after a second treatment. Patient questionnaires after one treatment revealed 50% satisfaction, with 60% willing to recommend the procedure and 60% reporting visible fat reduction. After second treatment, however, 100% were satisfied, 83% were willing to recommend, and 100% reported visible fat reduction. CONCLUSION Cryolipolysis with a nonvacuum conformable-surface applicator is safe, effective, and well tolerated for noninvasive reduction of fibrous periumbilical abdominal fat. Efficacy and subject satisfaction is significantly greater with 2 treatments than with a single session. Address correspondence and reprint requests to: Daniel P.
