Abstract:Objective To investigate long-term efficacy of subthalamic nucleus deep brain stimulation (STN-DBS) for the treatment of primary dystonia.Methods Clinical data of 34 patients with primary dystonia receiving bilateral STN-DBS treatment were analyzed retrospectively.All the patients were evaluated with Burke-Fahn-Marsden dystonia rating scale (BFMDRS) and 36-item short form (SF-36) of health survey before surgery and 1,12,24 months after surgery.The mean follow-up time was 5.5±2.5 years,ranged from 2 to 10 years,and 19 patients were followed up more than 5 years.Results All the patients experienced a remarkable long-term and stable improvement after stimulation.The motor scale of BFMDRS and SF-36 scores significantly improved 1 month after stimulation (P < 0.05),further improved 12 months after simulation (P < 0.05),and kept stable after 12 months.The adverse events included misplacement or breakage of the electrode,implant rejection and sustained depression.Conclusions STN-DBS implantation is significantly effective for primary dystonia,can significantly improve the motor symptoms and quality of life,and maintain stable long-term efficacy and longer working life.
