Stereotactic Gamma knife radiosurgery for idiopathic trigeminal neuralgia:analysis of long-term complications and treatment effect

Objective To study the long-term complications and treatment effect of stereotactic Gamma knife radiosurgery performed on idiopathic trigeminal neuralgia. Methods Long-term follow-up (5-8 years, 75.7 months average) was performed in 33 trigeminal neuralgia treated with Gamma knife in our department, the complications and degree of pain relief were recorded. Results Complications were noted in 15.1% of patients. The percentage of patients who achieved pain free or relieved significantly was 90.9% for short-term follow-up, and 75.7% for long-term follow-up. Conclusion Stereotactic Gamma knife radiosurgery for idiopathic trigeminal neuralgia could achieve good effect for long term, and the complications were light and occurred in a low rate. We recommend Gamma knife be treatment of choice for idiopathic trigeminal neuralgia.
