A novel anesthetic technique for palmar botulinum toxin injection

Botulinum toxin type A effectively treats persistent palmar hyperhidrosis, but treatment-associated pain limits utility.1 Topical anesthesia, ethyl chloride spray, and cold packs have shown limited success. Deep-wrist nerve blocks that target the median and ulnar nerves are effective but carry risks of vessel puncture, impaired hand dexterity, and needle-related nerve trauma. Because patients typically need repeated injections at regular intervals, the compounded risks make deep nerve blocks even less attractive.
