To use 3D photography to evaluate the clinical efficacy of a novel radiofrequency delivery device used to improve the appearance of rhytids and laxity of the face and neck.
Forty-nine subjects received a total of two radio-frequency treatments to the face and neck one-month apart. The novel radio-frequency delivery device was used to heat the dermis between 41-43°C for five heat cycles. Primary outcome measures were clinical efficacy quantified by the Global Assessment Improvement Scale (GAIS) and a patient survey that assessed treatment satisfaction.
Assessments of 3D photographs revealed an overall improvement in 74% of study subjects. 85% of patients noted an overall improvement in the appearance of their skin. 81% of patients rated their post-treatment skin laxity as improved, 85% rated their skin smoothness as improved and 62% rated their skin brightness as improved.
Subjects in this study demonstrated an overall improvement in face and neck appearance with regard to skin tightening, wrinkles, and skin texture suggested by overall patient satisfaction (85%) and physician-rated GAIS improvement (74%). This study suggests that radiofrequency applied with a continuous thermal treatment device is a safe and efficacious way to improve the overall appearance of aging facial skin.
使用三维摄影评估一种新型射频递送装置改善面部和颈部皱纹及皮肤松弛外观的临床疗效。
49名受试者在相隔一个月的时间里接受了总共两次面部和颈部的射频治疗。使用新型射频递送装置在41 - 43°C之间对真皮进行加热，共进行五个加热周期。主要结局指标是通过整体评估改善量表（GAIS）量化的临床疗效以及一项评估治疗满意度的患者调查。
对三维照片的评估显示，74%的研究受试者整体有所改善。85%的患者指出其皮肤外观整体有所改善。81%的患者将治疗后的皮肤松弛评为有所改善，85%将皮肤光滑度评为有所改善，62%将皮肤亮度评为有所改善。
本研究中的受试者在面部和颈部外观方面，在皮肤紧致、皱纹和皮肤质地方面整体有所改善，这由患者总体满意度（85%）和医生评定的GAIS改善情况（74%）表明。本研究表明，使用连续热疗装置进行射频治疗是改善衰老面部皮肤整体外观的一种安全有效的方法。
