Local treatment of spasmodic torticollis with botulinum toxin.

Abstract

Fifteen patients with spasmodic torticollis were treated with local injections of botulinum--A toxin. All the patients were followed for a period of 4 to 7 months. Thirteen out of 15 patients (86%) improved in the amount of sustained movements of torticollis. In six out of 9 patients presenting with pain complete relief was noted. Beneficial effects of botulinum toxin injections lasted from 2 to 3 months, with reproducible efficacy after repeated injections. The most frequent side effect was dysphagia, presented in 10 patients.
