Large-scale long-term retrospective study of noninsulated microneedle radiofrequency treatment on neck rejuvenation is lacking. We conducted a 3-year retrospective observation of subjects treated with noninsulated microneedle radiofrequency (NIMNRF) for neck rejuvenation in Chinese subjects. Of all subjects, 28 subjects (28.6%) received only 1 session of treatment. About 50% subjects achieved ≥ 50% improvement, and average improvements were 37.0% at 3 months follow-up (M3) and 41.6% at 6 months follow-up (M6). Seventy subjects (71.4%) accepted 3 sessions of treatments. The neck aging scores were 3.57 ± 1.28 at baseline, and significantly decreased to 1.10 ± 0.84 at M3 (p < 0.05), 1.04 ± 0.86 (p < 0.05) at M6, separately. The average improvements were 73.3% at M3 and 75.1% at M6. It showed a trend of better efficacy with the increasing number of sessions (p < 0.05). Among of 6 subjects who was followed up for 1 year, 5 subjects who received 3 sessions of treatment achieved about 70% improvement after final session, and another 1 subject who received 1 session remained the improvement up to 40%. The results demonstrate NIMNRF treatment has significant and long-lasting effect on neck laxity and wrinkle reduction with minimal discomfort and downtime.
目前缺乏关于非绝缘微针射频治疗颈部年轻化的大规模长期回顾性研究。我们对中国受试者进行了一项为期3年的回顾性观察，这些受试者接受了非绝缘微针射频（NIMNRF）治疗以实现颈部年轻化。在所有受试者中，28名受试者（28.6%）仅接受了1次治疗。约50%的受试者改善程度≥50%，在3个月随访（M3）时平均改善率为37.0%，在6个月随访（M6）时为41.6%。70名受试者（71.4%）接受了3次治疗。颈部衰老评分在基线时为3.57±1.28，在M3时显著降至1.10±0.84（p<0.05），在M6时为1.04±0.86（p<0.05）。M3时的平均改善率为73.3%，M6时为75.1%。随着治疗次数增加，疗效呈更好的趋势（p<0.05）。在随访1年的6名受试者中，接受3次治疗的5名受试者在最后一次治疗后改善程度约为70%，另一名接受1次治疗的受试者改善程度达40%。结果表明，非绝缘微针射频治疗对颈部松弛和皱纹减少具有显著且持久的效果，不适和停工期极小。
