Histopathological evidence of efficacy of microneedle radiofrequency for treatment of axillary hyperhidrosis.

Abstract

A major concern about the treatment of hyperhidrosis is the lack of clinical guidelines. Many medical (e.g. Botulinum toxin type A) and surgical methods have been used to overcome excessive sweating with variable results.[1] Energy-based devices have recently gained increasing acceptance for the treatment of many skin disorders and cosmetic conditions including facial rhytides and skin laxity.[2,3] Recently, some researchers clinically evaluated the use of radiofrequency (RF) energy in the treatment of primary axillary hyperhidrosis (PAH), which suggest that the bipolar radiofrequency devices are effective in reducing the amount of sweating,[4-6] but very limited published data on histological confirmation of successful treatment is available.
