Introduction Axillary hyperhidrosis and bromhidrosis have serious social, emotional, and professional consequences. There are several treatments of axillary hyperhidrosis. We present a case series evaluating the efficacy and safety of microwave device for axillary hyperhidrosis and bromhidrosis. Materials and methods Seven patients were included in our case series. Four patients had both hyperhidrosis and bromhidrosis. Three patients had only hyperhidrosis. To evaluate the degree of hyperhidrosis and degree bromhidrosis a self-reported Hyperhidrosis Disease Severity Scale (HDSS) score and 4-point malodor grade were assessed. All patients underwent 1 or 2 microwave treatments. Patients underwent a survey on treatment outcomes and adverse effect conducted through telephone 12 months after their last procedure. Results Six of seven patients had a 2-point drop in HDSS score. The four patients with bromhidrosis had a 2-point drop on the self-reported malodor measurement 12 months post treatment. Minor adverse effects related to the therapy occurred. Conclusion This novel microwave-based treatment was effective for the treatment of axillary hyperhidrosis and bromhidrosis. Patient satisfaction with the procedure is high, and adverse events are typically transient and well tolerated.
