Abstract

Thirteen subjects with trigeminal neuralgia were treated with botulinum-A neurotoxin (BoNT/A) in an open-label pilot study. After BoNT/A, visual analog scale score, surface area of pain, and therapeutic coefficient were reduced in all patients and for all branch trigeminal nerves studied. Therefore, BoNT/A is an efficient treatment. There were no major side effects. A placebo-controlled clinical trial is needed to confirm these findings.
