Abstract
BACKGROUND Unwanted lateral fat most prominently affects the female population and may cause self-esteem issues. OBJECTIVE To investigate the effectiveness and safety of synchronized high-intensity focused electromagnetic (HIFEM) + radiofrequency (RF) for the treatment of lateral thigh adipose tissue. MATERIALS AND METHODS Ninety-three subjects (21–70 year old) received 4, 30-minute HIFEM + RF treatments of the lateral thighs. Magnetic resonance imaging (MRI) of the treated area was obtained at baseline, 1, 3, and 6 months post-treatment to document the changes in fat layer thickness. Furthermore, digital photographs, circumference measurements of the lateral thighs, subjects' satisfaction questionnaires, and therapy safety and comfort were documented. RESULTS Magnetic resonance imaging revealed a significant reduction of fat tissue in the saddlebag region peaking at 3 months (−18 ± 5.5 mm; N = 51). The thigh circumference measured at 3 predefined levels decreased on average by 2.3 cm, with the greatest change at the level of 10 cm below the infragluteal fold (−3.5 cm, 3-month follow-up). Results were maintained at 6 months. No adverse events were recorded. The therapy was found comfortable with a high satisfaction rate. CONCLUSION High-intensity focused electromagnetic + RF treatment to the lateral thigh area demonstrated effectiveness in long-term fat thickness reduction by MRI imaging. Secondary endpoint showed simultaneous effectiveness and safety.
Non-RCTSynchronized high-intensity focused electromagnetic (HIFEM) + radiofrequency (RF) treatment effectively reduces long-term fat thickness in the lateral thigh area, with high satisfaction rates and no adverse events.
