The feasibility, safety, and efficacy of a novel radiofrequency device for radiofrequency-assisted liposuction were evaluated in various body areas.
From July to December of 2008, 23 subjects underwent radiofrequency-assisted liposuction using the BodyTite system. Information regarding aesthetic results and local and systemic complications was collected immediately after the procedure and at 6- and 12-week follow-up.
The mean age of the patients was 38.8 +/- 12.4 years, and 87 percent were women. Radiofrequency-assisted liposuction was performed successfully in all cases; volume aspirated per patient was 2404 +/- 1290 ml, whereas operative time was 158 +/- 44 minutes. All patients underwent liposuction at the hip and low abdominal areas, bilaterally. Body contour improvement was observed postoperatively in all patients and there were no severe systemic or local complications, although postoperative pain was minimal in all patients. Weight and circumference reductions were significant at both 6-week and 3-month follow-up. Skin tightening was judged optimal by the surgeon in all patients.
The authors' study suggests that the removal of moderate volumes of fat with concurrent subdermal tissue contraction can be performed safely and effectively with radiofrequency-assisted liposuction. Additional benefits of this technique are excellent patient tolerance and fast recovery time. Nonetheless, a larger sample is required to confirm the authors' results and guarantee the efficacy and safety of the procedure. Direct comparison with traditional liposuction or energy-assisted liposuction techniques may provide some insights to tailor future indications of this novel technique.
新型射频设备在辅助吸脂术中的可行性、安全性和有效性已在多个身体部位得到评估。
2008 年 7 月至 12 月，23 例患者接受了 BodyTite 系统辅助的射频吸脂术。术后即刻、术后 6 周和 12 周收集了有关美容效果和局部及全身并发症的信息。
患者的平均年龄为 38.8±12.4 岁，87%为女性。所有患者均成功进行了射频辅助吸脂术；每位患者抽吸的体积为 2404±1290ml，而手术时间为 158±44 分钟。所有患者均在双侧臀部和下腹部进行吸脂术。所有患者术后均观察到身体轮廓改善，无严重全身或局部并发症，尽管所有患者术后疼痛均轻微。术后 6 周和 3 个月随访时体重和周长均有明显下降。所有患者的皮肤收紧均由外科医生判断为最佳。
作者的研究表明，射频辅助吸脂术可安全有效地去除中等体积的脂肪并同时收缩皮下组织。该技术的其他优点是患者耐受性良好，恢复时间快。然而，需要更大的样本量来确认作者的结果并保证该手术的有效性和安全性。与传统吸脂术或能量辅助吸脂术的直接比较可能会为该新技术的未来适应证提供一些见解。
