Abstract:
To explore the efficacy and safety of fractional micro-needling radiofrequency (FMRF) in the treatment of enlarged pores on the cheek in a Chinese cohort. Patients with enlarged facial pores who underwent FMRF between January 2020 and December 2022 were included in this study. Blinded clinical assessments were performed by two independent dermatologists using a six-grade photographic enlarged pore scale and a quartile grading scale. Patients were asked to rate the degree of pain related to treatment on a visual analog scale (VAS), with scores ranging from 0 (no pain) to 10 (worst pain ever). A paired t-test was used to analyze the six-grade photographic enlarged pore scores. A total of 22 patients received three consecutive sessions of FMRF treatment, with intervals of 1-3 months, and underwent follow-up as scheduled. The mean six-grade photographic enlarged score was 3.55 ± 0.96 at baseline, while the score decreased significantly to 2.59 ± 0.59 after three treatment sessions (P < 0.05). The improvement score of the patients, assessed by two independent dermatologists, was 2.31 ± 0.71, according to the quartile grading scale. The mean VAS score was 6.42 ± 1.44. FMRF is effective and safe for the treatment of enlarged facial pores after three sessions.
摘要:
目的探讨中国队列患者局部微针射频(FMRF)治疗颊部毛孔增大的疗效和安全性。这项研究包括在2020年1月至2022年12月期间接受FMRF的面部毛孔增大患者。由两名独立的皮肤科医生使用六级摄影扩大毛孔量表和四分位数分级量表进行盲临床评估。要求患者以视觉模拟量表(VAS)对与治疗相关的疼痛程度进行评分,评分范围从0(无痛)到10(有史以来最严重的疼痛)。采用配对t检验分析六级摄影扩大毛孔评分。共有22名患者接受了连续3个疗程的FMRF治疗,间隔为1-3个月,并按计划进行了随访。基线时平均六级摄影放大评分为3.55±0.96,3次治疗后评分明显下降至2.59±0.59(P<0.05)。患者的改善评分,由两名独立的皮肤科医生评估,根据四分位数分级量表为2.31±0.71。平均VAS评分为6.42±1.44。FMRF在三个疗程后对面部毛孔增大的治疗是有效和安全的。
