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

Area of Science:

• Dermatology
• Anesthesiology
• Medical Procedures

Background:

• Botulinum toxin injections are widely used for cosmetic and therapeutic purposes.
• Topical anesthesia with eutectic mixtures of lignocaine and prilocaine is standard but often insufficient for palm injections.
• Pain during injection negatively impacts patient experience and adherence.

Purpose of the Study:

• To evaluate a modified hyper-occlusive technique for topical anesthesia of the palms prior to botulinum toxin injection.
• To determine if this modification enhances patient comfort and satisfaction.
• To assess the impact on patient compliance with future treatments.

Main Methods:

• A cohort of patients undergoing botulinum toxin injections on their palms were included.
• A hyper-occlusive dressing was applied over the eutectic mixture of lignocaine and prilocaine.
• Pain levels and patient satisfaction were assessed post-procedure.

Main Results:

• The hyper-occlusive modification resulted in significantly reduced pain during botulinum toxin injections.
• Patient satisfaction scores were markedly higher compared to standard topical anesthesia techniques.
• Improved comfort is expected to enhance patient compliance for subsequent treatments.

Conclusions:

• A simple hyper-occlusive modification significantly improves the efficacy of topical anesthesia for botulinum toxin injections on the palms.
• This technique offers a practical solution for reducing injection pain.
• Enhanced patient comfort and satisfaction can lead to better treatment adherence.
