Summary
Botulinum toxin injections effectively treat severe palmar hyperhidrosis, reducing sweat production for up to 12 months. This therapy offers a safe and long-lasting alternative for managing this chronic condition.
Area of Science:
- Dermatology
- Neurology
Background:
- Palmar hyperhidrosis is a chronic condition often resistant to traditional treatments.
- Botulinum toxin functions by inhibiting acetylcholine release, thereby reducing sweat production.
Purpose of the Study:
- To assess the short-term and long-term efficacy of botulinum toxin therapy for palmar hyperhidrosis.
Main Methods:
- Four patients with severe palmar hyperhidrosis received subepidermal botulinum toxin injections.
- Each palm was treated with 50 injections (2 mouse units each).
- Median and ulnar nerve blocks were administered prior to injections, with a 12-month follow-up period.
Main Results:
- Botulinum toxin injections significantly decreased sweat production in the palms.
- The duration of anhidrosis varied, lasting 4 to 12 months among patients.
- One patient experienced temporary mild thumb weakness, with no other adverse effects reported.
Conclusions:
- Botulinum toxin is a safe and effective long-term treatment option for severe palmar hyperhidrosis.
- Further research is recommended to optimize treatment techniques.
