Abstract
We aimed to evaluate the efficacy and safety of a fractional microneedle radiofrequency device (FMRD) for the treatment of primary axillary hyperhidrosis (PAH). The FMRD adopted insulated microneedles, which could be located at a depth of up to 4.5 mm and deliver a radiofrequency current in a fractional manner. Also, the device could automatically regulate the amount of the delivered energy. Sixteen Korean patients with PAH received two FMRD treatment sessions at a 3-week interval and were followed-up until week 15. The primary outcome was Patient Satisfaction Scale (PSS) score at each visit. Hyperhidrosis Disease Severity Scale (HDSS) and Global Aesthetic Improvement Scale (GAIS) were also assessed. The area and amount of sweat produced were evaluated by specific tests. Mean PSS score significantly improved from 1.6 at week 3 to 2.5 at week 15 by 56%. More than a 50% improvement in sweating assessed by the PSS score was seen in 63% and 50% of patients at weeks 11 and 15, respectively. Mean HDSS score significantly decreased by week 3 and further decreased by week 7. Mean GAIS scores improved from the first follow-up visit at week 3 and improved again at week 7. The mean hyperhidrosis area assessed by starch-iodine test significantly decreased by 36% at week 15 compared with baseline. Mean transepidermal water loss level significantly decreased by 42% at week 15 compared with baseline. No patients experienced any serious adverse events. FMRD can be an effective and safe treatment modality for PAH.
