Botulinum toxin in the therapy of gustatory sweating

J Neurol. 1996 Feb;243(2):143-6. doi: 10.1007/BF02444005.


Three patients suffering from gustatory sweating following trauma to the preauricular region from a bullet wound or parotid gland surgery were treated by intracutaneous injection of botulinum toxin A. Within 2 weeks, gustatory sweating in the area injected completely ceased in all patients with no side-effects. The efficacy of treatment was confirmed by repeated Minor's iodine starch tests. So far, sweating has not recurred during a follow-up period of up to 8 months. Botulinum toxin appears to be a promising new drug for the treatment of this autonomic disorder.
