Botulinum toxin: An effective treatment for prosthesis-related hyperhidrosis in patients with traumatic amputations

Hyperhidrosis-related to prosthesis use in patients who have suffered a traumatic limb amputation presents itself as a barrier to comfort, prosthesis use and overall quality of life. This review intends to encourage dermatologists to consider the use of botulinum toxin A or B for the treatment of hyperhidrosis in the residual limb and may serve as a stimulus for a modern, in-depth, and more comprehensive study. A review of the literature was conducted using the PubMed database, focusing on hyperhidrosis treatment after traumatic limb amputation. Articles discussing hyperhidrosis treatment for amputations secondary to chronic medical conditions were excluded. Seven case studies published over the last 12 years have demonstrated positive outcomes of this treatment strategy. Overall, there is little data examining this topic and current publications focus primarily on small case series. A larger, double-blind, placebo-controlled study would likely benefit veterans, service members, and civilians.
