![]() ![]() At a median follow-up time of 14.2 months, 19 patients (95%) reported at least some improvement in pain. Barrow Neurological Index (BNI) pain scale for TN was used for assessing treatment outcome. In addition, specially acquired three-dimensional fast imaging sequence employing steady-state acquisition (FIESTA) MRI was utilized to improve target delineation of the trigeminal proximal nerve root entry zone. ![]() The median brainstem dose to 1.0 cc and 0.1 cc was 2.3 Gy and 13.5 Gy, respectively. Majority of the patients received a maximum dose of 90 Gy. Thin cuts MRI images of 1.5 mm thickness were acquired and fused with the simulation CT of each patient. Each SRS procedure was performed using the BrainLAB Novalis System. A total of 20 patients were treated between July 2004 and February 2007. We describe our initial experience of using BrainLAB Novalis stereotactic system for the radiosurgical treatment of TN. To date, most reports have been about Cobalt-based treatments (i.e., Gamma Knife) with limited data on image-guided stereotactic linear accelerator treatments. Stereotactic radiosurgery (SRS) is one of the least invasive treatments for trigeminal neuralgia (TN).
