[CyberKnife stereotactic radiosurgery in the treatment of patients with trigeminal neuralgia].

摘要

Trigeminal neuralgia (TN) is a disabling disease with severe impairment of quality of life and everyday activity of patients. Range of treatment modalities is wide and includes conservative therapy, surgical methods and stereotactic radiosurgery (SRS). SRS is a minimally invasive technique which provides good results and minimal rate of complications. High geometrical and clinical precision of frameless SRS using CyberKnife system allows its application in TN when high dose is delivered to a small volume. The given paper focuses on the first Russian experience of frameless SRS of TN using robotized system CyberKnife. Since April 2009 till June 2011 4 patients with TN were treated in department for radiation therapy of Burdenko Neurosurgical Institute using CyberKnife system. Mean age was 63 years. Mean and maximal target dose reached 70 and 90 Gy, respectively. Data of catamnestic clinical examination were available in all 4 patients. Follow-up period reached 8 months. Response to treatment was observed in all cases. In 2 (50%) patients full effect was reached while in the rest only partial effect was present. No complications were encountered. Effectiveness and safety of SRS using CyberKnife system is comparable with framed SRS.
