Abstract

Microwave energy technology treats axillary hyperhidrosis through thermolysis of the apocrine and eccrine glands. Successful short-term reduction of sweating has been studied, but there is limited information on long-term efficacy and safety. To evaluate patient satisfaction with microwave energy device for axillary hyperhidrosis performed within the last 5 years. From June to August 2019, a standardized telephone survey was conducted of 24 patients who received microwave energy device treatment for bilateral axillary hyperhidrosis between June 2014 and June 2018. Demographic information, previous treatment modalities, sweat reduction scores, and side effects were reported. Eighteen patients completed the survey with a mean follow-up of 38 months (range 12-52). The mean hyperhidrosis disease severity scale (HDSS) was reduced by 1.6 (95% CI 1.2-2.0, p < .01). The mean sweat reduction was 61-70%. Sixty-seven percent of patients experienced a reduction in odor and 54% did not require deodorant after treatment. Adverse effects included bruising (67%), pain (56%), swelling (44%), numbness (28%), and nodules (22%). Sixty-six percent of side effects resolved within 2 weeks and all side effects resolved within 12 weeks. The microwave energy device is an effective, durable therapy for axillary hyperhidrosis associated with minimal downtime and a high degree of long-term patient satisfaction.
