Some faciomaxillary surgeons are using a derivative of the toxin from Clostridium botulinum (Botox) to weaken muscles that cause frown line problems. Botox has been used effectively in treatment of overactive muscle problems including over-blinking and facial tics. Botox has been used in some patients with dystonia not related to Parkinsons. Does anyone know of a parkinsonian with dystonia who has had good or bad results with Botox? And YES, Botox comes from the bacillus that causes botulism - food poisoning.
