Monopolar radiofrequency is an effective means of nonsurgical facial skin tightening.
The objective of this study was to determine whether using larger tips at lower energy and multiple passes, using patient feedback on heat sensation and treating to a clinical end point of visible tightening, would yield better results than single passes with small tips at high energy, as measured by patient and physician satisfaction.
Fourteen physicians from four specialties were surveyed to determine the answers to the following three questions. (1) Is patient's feedback on heat sensation a valid and preferred method for optimal energy selection? (2) Do multiple passes at moderate energy settings yield substantial and consistent efficacy? (3) Is treating to a clinical end point of visible tightening predictable of results?
A total of 5,700 patient treatments were surveyed. Comparisons were made using the original algorithm of high-energy, single pass to the new algorithm of lower energy and multiple passes with visible tightening as the end point of treatment. Using the original treatment algorithm, 26% of patients demonstrated immediate tightening, 54% observed skin tightening 6 months after treatment, 45% found the procedure too painful, and 68% of patients found the treatment results met their expectations. With the new multiple-pass algorithm, 87% observed immediate tightening, 92% had the tightening six months after treatment, 5% found the procedure too painful, while 94% found the treatment results met their expectations.
Patient feedback on heat sensation is a valid, preferable method for optimal energy selection in monopolar radiofrequency skin-tightening treatments.
单极射频是一种有效的非手术面部皮肤紧致方法。
本研究的目的是确定在较低能量下使用较大的治疗头并进行多次治疗,根据患者对热感的反馈并治疗至可见紧致的临床终点,与在高能量下使用小治疗头单次治疗相比,是否能产生更好的效果,评估指标为患者和医生的满意度。
对来自四个专业的14名医生进行调查,以确定对以下三个问题的答案。(1)患者对热感的反馈是否是选择最佳能量的有效且首选方法?(2)在中等能量设置下进行多次治疗是否能产生显著且一致的疗效?(3)将治疗至可见紧致的临床终点作为结果的预测指标是否可行?
共调查了5700例患者治疗情况。将使用高能量单次治疗的原始算法与以可见紧致为治疗终点的低能量多次治疗新算法进行比较。使用原始治疗算法时,26%的患者出现即时紧致,54%的患者在治疗6个月后观察到皮肤紧致,45%的患者认为该过程过于疼痛,68%的患者认为治疗结果符合其期望。采用新的多次治疗算法时,87%的患者出现即时紧致,92%的患者在治疗6个月后出现紧致,5%的患者认为该过程过于疼痛,而94%的患者认为治疗结果符合其期望。
在单极射频皮肤紧致治疗中,患者对热感的反馈是选择最佳能量的有效且首选方法。
