Safety and efficacy of a non-contact radiofrequency device for body contouring in Asians

초록

Background: The non-invasive reduction of subcutaneous abdominal fat became popular. Radiofrequency, non-contact, selective-field device Vanquish (R) has been developed to selectively induce deep fat tissue heating to reduce waist circumference. Objective: The objective of this study was to evaluate the efficacy and safety of clinical, radiological results of the radiofrequency, non-contact, selective-field device treatment. Methods: Twelve healthy individuals with no underlying medical problem were treated with five sessions of radiofrequency treatment to reduce abdominal subcutaneous fat. 45-minute sessions were performed with an 1-week interval. For efficacy evaluation, patient's abdominal circumferences and body weight were measured, and photographs were taken at baseline and each follow-up visit for 12 weeks. One subject was examined with computed tomography (CT) before the first session and six weeks after the first CT scan, and we measured the volume of subcutaneous fat layer. Any adverse effect was assessed during the entire study period. Results: Reduction in abdominal circumferences was noted in most participants (10 of 12 patients). No serious adverse effect was reported. Volume reduction of abdominal subcutaneous fat layer was confirmed in a subject who took CT scan. Conclusions: Our study shows that the selective-field radiofrequency treatment seems to be safe and efficient for reduction of abdominal subcutaneous fat.
