Microwave Sweat Treatment Holds Results Three Years Later
A Swedish study tracking 45 patients found that microwave therapy for severe underarm sweating maintained its effectiveness over three years, with significant quality-of-life improvements persisting. The finding matters to dermatology practices and medtech companies developing long-term treatment protocols for a condition affecting millions globally.
Originaltitel: Three-Year Results Following Microwave Therapy in Patients with Severe Primary Axillary Hyperhidrosis
<p>Microwave therapy (Miradry (R)) is an approved treatment for axillary hyperhidrosis (AH). There are several studies in the literature that show favourable safety and efficacy profile, although a few follow up patients under longer period and on larger cohort patients. In the present study, we report three-year results after microwave therapy for AH. At dermatology clinic in & Ouml;sterg & ouml;tland 103 patients with severe AH received one or two Miradry (R) treatments, between 2020 and 2022. Patients were examined at several intervals during study period. Between March 2024 and June 2025, 87 patients were contacted by post and asked to complete HDSS (Hyperhidrosis Disease Severity Scale) and Hyperhidrosis Quality of Life (HidroQoL (c)); 45 patients have responded to our survey (response rate 51.7%). Statistically significant improvement was observed in both HDSS (from medians 3 at the study inclusion to medians 2 at 3 year) and HidroQoL (c) (medians 26 at baseline and medians 6 at 3 year). As a conclusion, our data demonstrate that microwave therapy is a promising long-term efficient treatment for AH and significantly improves quality of life in patients suffering from severe AH.</p>
