VOI thalamotomy in spasmodic torticollis
Applied Neurophysiology
|January 1, 1980
Summary
Stereotactic VOI thalamotomy effectively treated spasmodic torticollis in 17 patients. Most patients experienced delayed improvement, but all ultimately recovered, regardless of initial psychological state.
Area of Science:
- Neurosurgery
- Neurology
- Movement Disorders
Background:
- Spasmodic torticollis is a debilitating movement disorder characterized by involuntary neck muscle contractions.
- Surgical interventions are considered for refractory cases.
- Thalamotomy has been explored as a treatment option.
Purpose of the Study:
- To evaluate the efficacy of stereotactic Ventralis Oralis (VOI) thalamotomy as a surgical treatment for spasmodic torticollis.
Main Methods:
- Stereotactic VOI thalamotomy was performed as the sole surgical intervention.
- Seventeen patients with spasmodic torticollis, primarily horizontal type, were included.
- Patient outcomes were assessed postoperatively.
Main Results:
- All patients demonstrated improvement following unilateral thalamotomy.
- Delayed improvement was observed in most cases, ranging from 3 months to 2-3 years.
- Preoperative psychological disturbances did not correlate with the final surgical outcome.
Conclusions:
- Stereotactic VOI thalamotomy is an effective surgical treatment for spasmodic torticollis.
- Delayed recovery is a common feature, necessitating long-term follow-up.
- Patient psychological status does not predict surgical success.
