Abstract
ObjectiveTo evaluate the safety and efficiency of deep brain stimulation (DBS) in the treatment of spasmodic torticollis (ST) and to compare the difference between the efficiency of STN (subthalamic nucleus)-DBS and GPi (globus pallidus internus)-DBS.
MethodsFourteen patients underwent DBS from February 2005 to February 2018 at Neurosurgery Department of Beijing Tiantan Hospital, Capital Medical University and were retrospectively enrolled into our study. Seven cases were treated with STN-DBS and seven cases with GPi-DBS. The effects of stimulation on cervical dystonia were analyzed based on the Toronto Western Spasmodic Torticollis Scale (TWSTRS). The scores were collected at baseline and the latest follow-up. Related side effects were also documented.
ResultsThe fourteen patients were followed up for the median of 24 (3-150) months. Eleven out of fourteen patients showed a significant improvement from baseline in TWSTRS (P=0.003). The median improvement rate was 69.6% (46.2%-83.6%). However, there was no significant difference between STN-DBS and GPi-DBS with the improvement rates of 69.8%(46.2%-83.6%) and 68.7%(56.0%-74.0%) respectively (P=1.000). Of all 14 patients, there was 1 case of lead breakage, 4 cases of dyskinesia, 1 case of face tic and 1 case of dysarthria, dysphagia and neck fatigue.
ConclusionDBS seems to be an effective and safe therapy method of ST. Both STN and GPi are effective targets for the treatment of ST.
