目的：观察一种新的射频技术———聚焦射频技术在面部年轻化中的应用效果。方法2015年10月至2016年2月，20名面部皮肤松弛患者接受聚焦射频治疗，分别在治疗前及治疗后3个月（3次）进行面部标准化照片拍摄，并测量双侧鼻唇沟长度和双侧鼻唇沟夹角。结果治疗前与治疗后3个月比较，两侧鼻唇沟长度均显著变短（P<0.05）。双侧鼻唇沟夹角治疗前为59.69°±7.42°，治疗后3个月为59.36°±5.65°，无显著性差异（P>0.05）。结论聚焦射频能有效改善面部皮肤松弛，尤其可显著改善鼻唇沟长度。%Objective To investigate the effectiveness of a novel radiofrequency system:focused-radiofrequency system on facial rejuvenation. Methods From October 2015 to February 2016, 20 patients with facial aging skin accepted the focused-radiofrequency therapy. Standard photographs and digitized measurement were taken before the therapy and 3 months after the therapy. The length of the bilateral nasolabial fold and the angle of bilateral nasolabial fold were measured. Results Compared with pre-treatment, the length of bilateral nasolabial fold 3 months after the therapy was significantly reduced (P<0.05). The angles of bilateral nasolabial fold before the therapy and 3 months after the therapy were 59.69 °±7.42 ° and 59.36 °±5.65 ° respectively, no significant difference was observed (P>0.05). Conclusion Focused-radiofrequency is an effective treatment for facial rejuvenation, especially in improving the length of nasolabial fold.
