Non-invasive focused ultrasound for abdominal circumference reduction: does it really work?

Aim:Non-invasive body contouring is a promising modality. However, due to a lack of good evidence-based data, the mechanism by which contouring occurs remains unclear. The purpose of this study was to evaluate the effect of treatment with the Contour I? ultrasound system (Ultrashape?, Syneron?, Isra...

description Aim:Non-invasive body contouring is a promising modality. However, due to a lack of good evidence-based data, the mechanism by which contouring occurs remains unclear. The purpose of this study was to evaluate the effect of treatment with the Contour I? ultrasound system (Ultrashape?, Syneron?, Israel) on abdominal circumference and to compare 2 power levels for efifcacy and safety. Methods:A prospective, self-controlled double-blind design was used. Thirty-six women, aged 30-45 years, were randomized to receive treatment with the Contour I at high or low acoustic outputs in 3 successive sessions, 1 month apart. Safety was evaluated by adverse events, local skin reaction, and pain. Efifcacy was evaluated by the change in abdominal circumference relative to baseline and to the untreated thigh area (internal control). Patients were followed for 28 days after the last treatment session. Results:At 1 month after the ifrst session, the mean reductions in abdominal circumference measured 1.65 cm (P

At 1 month after the last session, the cumulative reductions in circumference were 2.56 cm (P&lt;0.001) and 1.49 cm (P&lt;0.012), respectively. There was no change in the internal-control circumference throughout treatment. There were no treatment-induced severe adverse events. Conclusion: Multiple successive treatments of the abdominal area with the Contour I lead to a signiifcant progressive reduction in circumference.
