FREYS-SYNDROME - TREATMENT WITH BOTULINUM TOXIN

The effectiveness of botulinum toxin injections for the management of Frey's syndrome was studied. Botulinum toxin A (similar to 0.5 Units/c m(2)) was injected intracutaneously into the affected skin area as det ermined by Minor's starch iodine test. Gustatory sweating in the treat ed skin area ceased completely within 1 week and has not reappeared (1 2 months follow up until now in the first treated case). There have be en no side effects. It is concluded that local botulinum toxin injecti ons are a highly effective and safe treatment for Frey's syndrome. Add itional study is required to evaluate the duration of the therapeutic effect.
