Ultra-Early Gamma Knife Stereotactic Radiosurgery for TN

Sponsor: University of Alberta

Summary

The goal of this clinical trial is to evaluate the feasibility and potential benefit of Gamma Knife stereotactic radiosurgery (GK-SRS) as an ultra-early treatment option for trigeminal neuralgia (TN). The main questions it aims to answer are: 1. will earlier GK-SRS provide more durable pain relief compared to later GK-SRS? 2. will earlier GK-SRS reduce or eliminate the need for high-dose medical therapy? 3. will earlier GK-SRS have a lower risk of serious complications compared to other first-line treatments? If participants are assigned to GK-SRS treatment group, they will be asked to: • Undergo a preoperative MRI, measurements of heart rate and blood pressure, stereotactic head-frame placement, post-operative management and observation. Both groups will be asked to: * Complete medical histories and neurological examinations. These are part of standard of care. * Participants will be asked a series of questions related to overall physical health, pain severity, and mood. Completing these questionnaires is part of the research activity. It will take approximately 15- 30 minutes to complete. These questionnaires include: The Barrow Neurological Institute Pain Intensity Score, Brief Pain Inventory-Facial (BPI-Facial), Visual Analog Scale (VAS), Medication Quantification Scale (MQS), Hospital Anxiety and Depression Scale (HADS), Pain Catastrophizing Scale (PCS), and the Short Form Health Survey.
