Background:
Radiofrequency microneedling (RFM) is a potential treatment for primary hyperhidrosis. However, its efficacy is unclear, and treatment parameters and outcomes vary across studies.
Objective:
To understand the effect of RFM on treating primary hyperhidrosis, as measured by changes in the Hyperhidrosis Disease Severity Score (HDSS) before and after treatment, and to clearly define treatment settings most likely to optimize results.
Materials And Methods:
A systematic literature search utilizing Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was conducted across PubMed, EMBASE, MEDLINE, Web of Science, and the Cochrane Library. Studies were evaluated for risk of bias via the ROBINS-I tool and Levels of Evidence/GRADE criteria. A random forest model identified RFM settings that predict HDSS score decrease.
Results:
Six publications met inclusion criteria. The level of evidence was classified as Grade B, indicating moderate quality. RFM intervention resulted in a mean HDSS score decrease of 1.63 (52% reduction, p < .05). The strongest predictors for HDSS score decrease were dwell time, energy, and depth, with feature importances of 0.43, 0.19, and 0.15 respectively.
Conclusion:
Radiofrequency microneedling treatment significantly reduces HDSS scores in patients with primary hyperhidrosis. Moving forward, it would benefit physicians to standardize objective protocols in reporting RFM parameters and measuring outcomes.
