Fractionated microneedle radiofrequency versus botuinum toxin A in primary axillary hyperhidrosis

Primary axillary hyperhidrosis (PAH) is a chronic idiopathic disorder of excessive sweating that affects the axillae. Treatment options include topical application of aluminum chloride, administration of anticholinergic agents and beta-blockers, tap water iontophoresis, botulinum toxin A (BTX-A) injection, excision and suction curettage of sweat glands, or transthoracic endoscopic sympathectomy. Radiofrequency (RF) has recently emerged as a new therapeutic modality in PAH.This study aims at comparing the efficacy and safety of fractionated microneedle radiofrequency with Botulinum toxin A injection in primary axillary hyperhidrosis.
