A split‐body study evaluating the efficacy of a conformable surface cryolipolysis applicator for the treatment of male pseudogynecomastia

BACKGROUND: Cryolipolysis is a non-invasive method of body shaping that has been used for male pseudogynecomastia. However, traditional vacuum suction cryolipolysis requires a minimum pinchable fat layer which may not always be present in this area. OBJECTIVE: To evaluate the efficacy and safety of a conformable surface cryolipolysis applicator for the reduction of male pseudogynecomastia. MATERIALS AND METHODS: Ten male subjects with pseudogynecomastia received two cycles of cryolipolysis to the breast 6 weeks apart. Ultrasound was used to measure the thickness of adipose tissue. RESULTS: Seven of 10 patients completed the study. Compared to baseline, the mean ± SD change in adipose tissue thickness was 8.12 ± 6.94 mm for the treated versus 1.03 ± 6.03 mm for the control breast at week 6 (p = 0.014), and 8.71 ± 7.04 mm for the treated vs. 2.66 ± 7.04 mm for the control breast at week 12 (P = 0.16). Four (4) of seven (57%) patients were at least slightly satisfied with the treated breast, and although subject satisfaction was higher in the treated breast, this did not reach significance (0.085). Adverse events were mild and transient. CONCLUSION: A conformable surface cryolipolysis applicator was effective in reducing the mean adipose tissue thickness in subjects with male pseudogynecomastia. Lasers Surg.
