Purpose

The investigators know little about how patients feel following radiosurgery treatment of trigeminal neuralgia. Patient satisfaction may ultimately be one of the most important outcome measures for an individual patient; however, this has not been adequately assessed or followed. Multiple questions remain unanswered, including whether there is a correlation between patient satisfaction, the level of their current pain score, and the presence and degree of facial numbness, a possible side effect after radiosurgery. Therefore, the goal of this study is to gather this information from the patients who received radiosurgery for trigeminal neuralgia at Stanford and evaluate post-treatment patient satisfaction, the degree of facial numbness, and current pain score. This data will help the investigators understand outcomes that are important for patient satisfaction following treatment of a chronic pain syndrome.
