Hyperocclusive technique for topical anesthesia for injecting botulinum toxin in palmar hyperhidrosis.

Abstract

Injecting botulinum toxin under simple topical anesthesia using a eutectic mixture of lignocaine and prilocaine is a painful procedure. A simple hyper-occlusive modification in the existing technique of topical anesthesia of palms facilitates painless injections leading to greater patient satisfaction and compliance.
