Description
Summary:Introduction Previous studies demonstrated that multiple treatments using focused ultrasound can be effective as an non‐invasive method for reducing unwanted localized fat deposits. The objective of the study is to investigate the safety and efficacy of this focused ultrasound device in body contouring in Asians. Method Fifty‐three (51 females and 2 males) patients were enrolled into the study. Subjects had up to three treatment sessions with approximately 1‐month interval in between treatment. Efficacy was assessed by changes in abdominal circumference, ultrasound fat thickness, and caliper fat thickness. Weight change was monitored to distinguish weight loss induced changes in these measurements. Patient questionnaire was completed after each treatment. The level of pain or discomfort, improvement in body contour and overall satisfaction were graded with a score of 1–5 (1 being the least). Any adverse effects such as erythema, pain during treatment or blistering were recorded. Result The overall satisfaction amongst subjects was poor. Objective measurements by ultrasound, abdominal circumference, and caliper did not show significant difference after treatment. There is a negative correlation between the abdominal fat thickness and number of shots per treatment session. Conclusion Focused ultrasound is not effective for non‐invasive body contouring among Southern Asians as compared with Caucasian. Such observation is likely due to smaller body figures. Design modifications can overcome this problem and in doing so, improve clinical outcome. Lasers Surg. Med. 41:751–759, 2009. © 2009 Wiley‐Liss, Inc.
