Management of spasmodic torticollis.

Based on a review of the literature, the management of spasmodic torticollis may begin with the conservative measures of pharmacotherapy, sensory feedback, or percutaneous dorsal column stimulation. Approximately 50% of patients will benefit from an adequate trial of these modalities. With particularly resistant and disabling torticollis, the ablative procedures of microsurgical cervical rhizotomy or stereotaxic thalamotomy have offered significant relief in about 74% and 56%, respectively, of properly selected cases. Nevertheless, the variability in the duration of response to all forms of therapy has made the treatment of spasmodic torticollis a difficult and often frustrating undertaking.
