Abstract：
OBJECTIVE: This study aimed to evaluate the safety and efficacy of a novel therapeutic strategy, a microneedle fractional radiofrequency system, for hand rejuvenation.
METHODS: Sixteen subjects were enrolled in a self-controlled evaluator-blind prospective trial. All subjects received three microneedle fractional radiofrequency treatments at 4 weeks intervals. Hand volume was evaluated through subjective (Hand Volume Rating Scale) and quantitative measurements. Patients were also assessed on the Global Aesthetic Improvement Scale using digital photographs. Patients were followed up at 1, 3, and 6 months after the last radiofrequency treatment.
RESULTS: Statistically significant improvements on the Global Aesthetic Improvement Scale and Hand Rating Volume Scale were noted (p < 0.05). Compared with the control side, the treated hand showed a 44% improvement in dorsal skin surface roughness (p < 0.05). Quantitative measurements of hand volume showed a trend toward increased volume for the treated hand, but the difference was not statistically significant.
CONCLUSIONS: We conclude that microneedle fractional radiofrequency is a safe therapeutic option for hand rejuvenation.

摘要：
目的：本研究旨在评估一种新型治疗策略的安全性和有效性，微针部分射频系统,手的复兴。
方法：16名受试者被纳入一项自我对照评估者盲前瞻性试验。所有受试者以4周的间隔接受三根微针部分射频治疗。通过主观(手体积评定量表)和定量测量来评估手体积。还使用数码照片在全球美学改善量表上对患者进行了评估。在最后一次射频治疗后1、3和6个月对患者进行随访。
结果：注意到总体美学改善量表和手体积评分量表的统计学显着改善（p<0.05）。与控制侧相比，经处理的手显示背侧皮肤表面粗糙度改善44%(p<0.05)。手体积的定量测量显示，治疗手的体积有增加的趋势，但差异无统计学意义。
结论：我们得出结论，微针部分射频是手部年轻化的安全治疗选择。
