Gyroscopic Radiosurgery for Trigeminal Neuralgia Treatment

This article is a research report detailing the clinical results and dosimetric parameters of gyroscopic frameless radiosurgery (GRS) for treating trigeminal neuralgia (TN). The study involved 30 patients who underwent GRS between February 2023 and January 2025, with a maximum dose of 90 Gy delivered to a 5-mm segment of the trigeminal nerve. The report outlines patient demographics, previous treatments, and pain intensity scale scores before and after GRS. Results indicated that the median age of patients was 66 years, with a median time from diagnosis to GRS of 4 years. The median pain intensity scale improved from IV to II post-treatment, with 80% of patients reporting no pain or occasional pain without medication. The article also discusses treatment planning, dose delivery, and the safety profile of GRS, noting complications such as facial hypesthesia and recurrence of pain in some patients. Overall, GRS is presented as a precise and effective tool for managing refractory TN.
