双极射频对中国人皮肤松弛的紧缩作用

Bipolar radiofrequency （RF） for skin tightening in Chinese

目的评价双极射频Aluma（functional aspiration-controlled electrothermal stimulation，FACES）对面部皮肤松弛无创紧缩治疗的安全性及有效性。方法对39例中国人美容就医者，皮肤类型Ⅲ～Ⅳ，面部皮肤松弛合并眶周皱纹，接受Aluma（功率6～10w）治疗，每10d治疗1次，共5次。每次治疗前和末次治疗后1和3个月进行照像及临床评价。由医者及美容就医者本人据临床和照片共同评价，以鉴定皮肤松弛程度的改善。结果持续5次治疗后3个月，统计学显示颊部皮肤松弛显著改善（P〈0．05）；眶周、鼻唇沟和上颈部皮肤松弛得到轻度至中度改善，且没有严重的并发症。结论双极射频技术对中国人面部皮肤松弛有改善的效果，且无严重副作用。但此项技术的长期效果和最佳治疗参数还有待深入观察和研究。

Objective To evaluate the safety and efficacy of a device that called bipolar RF （Aluma） for non-ablative treatment of facial laxity. Methods Thirty-nine Chinese volunteers of skin types Ⅲ-Ⅳ, with facial laxity and periorbital rhytides, received five times treatments at 10 days interval with Aluma RF energies （6-10 W）. Standardized photographs were taken at baseline and serially for 3 months after the last treatment. The photographs were evaluated to assess the improvement in skin laxity by both doctors and patients. Results At 1-3 months after the last treatment, the results showed significantly subjective improvement in skin laxity of cheek （P〈0.05）, and mild to moderate subjective improvement in skin laxity of periorbital area, nasolabial fold and upper neck. There was no serious complication. Conclusion The bipolar radiofrequency produces mild to moderate improvement of facial laxity in Chinese with no serious adverse sequelae. A high patients＇satisfaction is achieved. However, further studies are necessary to demonstrate the long-term effects of the procedure and to optimize treatment parameters.
