Abstract

BACKGROUND Palmar and plantar hyperhidrosis (HH) is a common condition characterized by excessive sweating of the palms and soles. Botulinum neurotoxin (BTX) is a very effective and safe treatment. However, the associated intense injection pain is a major limiting factor deterring patients from selecting this treatment. OBJECTIVE The aim of this study was to review the numerous techniques used to minimize pain accompanying injections for palmoplantar HH. Additionally, the advantages and limitations of each modality will be discussed. MATERIALS AND METHODS The authors performed a comprehensive literature search in PubMed/MEDLINE, Embase, Cochrane Central, and Google Scholar on randomized controlled trials, cohort studies, and case series on techniques to relieve pain of BTX injections for treatment of palmar and plantar HH. RESULTS Current available techniques in reducing botulinum injection with merits and drawbacks are nerve blocks, Bier blocks, cryoanalgesia, needle-free anesthesia, topical anesthetics, and vibration anesthesia. CONCLUSION Topical anesthesia, ice, and vibration are the safest and most convenient noninvasive available methods to relieve pain associated with botulinum injection. Nerve blocks, Bier block, and needle-free anesthesia provide better anesthesia but are limited by the need for training and equipment.
