A dose of 60 Gy dose was administered 1 to 2 mm from the root entry zone with a maximum isodose of 20% delivered to the brainstem. Clinical results for pain control and any " side effects were analysed at 12 and 36 months (BNI score).Results: The study included 71 patients (mean follow-up 50.5 months). Pain improvement at 12 months was observed in 68.11% of the total (28.98% with BNI score Hi; 39.12% with BNI score III) and at 36 months in 58.21% (23.88% BNI score I-II; 34.32% BNI score III). Average recovery time was 3.69 months and the relapse rate was 44.68%. Patients with typical pain displayed statistically significant differences in improvement rates at 12 and at 36 months (PenAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Trigeminal neuralgiaRadiosurgeryLinear acceleratorTypical painNeurosurgeryFacial numbnessGamma-knife surgeryStereotactic radiosurgeryRecurrentNerveZoneresearch articleopen access10.1016/j.nrl.2015.10.0031578-1968https://doi.org/10.1016/j.nrl.2015.10.003398335100005
