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.
探究在中国人群中，微针点阵射频（FMRF）治疗面颊部毛孔粗大的疗效和安全性。
本研究纳入了 2020 年 1 月至 2022 年 12 月期间接受 FMRF 治疗的面部毛孔粗大患者。两名独立的皮肤科医生使用六级照片毛孔粗大量表和四分位分级量表进行盲法临床评估。患者使用视觉模拟评分法（VAS）对与治疗相关的疼痛程度进行评分，分值范围为 0（无痛）至 10（最痛）。使用配对 t 检验分析六级照片毛孔粗大评分。
共 22 例患者接受了三次连续的 FMRF 治疗，间隔 1-3 个月，并按计划进行随访。基线时六级照片毛孔粗大平均评分 3.55±0.96，三次治疗后评分显著降至 2.59±0.59（P<0.05）。根据四分位分级量表，两名独立皮肤科医生评估的患者改善评分为 2.31±0.71。VAS 平均评分 6.42±1.44。
三次治疗后，FMRF 治疗面部毛孔粗大有效且安全。
