Palmar and plantar hyperhidrosis: best practice recommendations and special considerations

Area of Science:

• Dermatology
• Neurology

Background:

• Palmar and plantar hyperhidrosis (HH) significantly impact quality of life.
• Topical therapies and tap water iontophoresis (TWI) are first-line treatments but may be insufficient.
• Botulinum toxin type A (BTX-A) offers an alternative when initial treatments fail or are not tolerated.

Purpose of the Study:

• To provide best practice guidelines for using BTX-A to treat palmar and plantar hyperhidrosis.
• To detail essential techniques, including dilution, injection methods, dosage, and anesthesia.
• To address practical considerations such as insurance reimbursement for BTX-A therapy.

Main Methods:

• Review of current literature and expert consensus on BTX-A application for HH.
• Description of specific techniques for precise injection in highly innervated areas (palms and soles).
• Discussion of patient selection, pre-injection preparation, and post-injection care.

Main Results:

• BTX-A (Botox) requires careful technique due to dense innervation in palms and soles.
• Specific recommendations provided for dilution, syringe choice, injection grids, and anesthesia.
• Guidance on navigating insurance coverage challenges for BTX-A treatment of HH.

Conclusions:

• BTX-A is a viable and effective treatment option for palmar and plantar hyperhidrosis.
• Adherence to best practice techniques ensures optimal outcomes and patient safety.
• Understanding the insurance landscape is crucial for patient access to BTX-A therapy.
