[The surgical results in patients with different forms of torsion dystonia].

The paper describes stereotactic operations made in 278 patients with different forms of torsion dystonia during 20 years. Late outcomes were studied and assessed in 130 patients. The duration of follow-ups was 3 to 23 years. The patients' mean age at surgery was 30.5 years. The indications for surgical treatment were ineffective medical treatment and progressive disease. Positive early and late postoperative outcomes were achieved in 93 and 70% of patients, respectively. Complications developed in 3.2 and 12.3% of patients after the first and second operations, respectively. The positive outcome depends on the form, etiology, the destructible structure or a complex of structures. Surgical treatment of patients with torsion dystonia by stereotactic operations on basal ganglia is an effective treatment that provides a steady-state positive result in 70% of patients in the late period.
