Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Patients will be evaluated by a multi-disciplinary team composed of radiation oncologists and neurosurgeons. During their visit, a physician or research coordinator will explain the study. Patients will be given the informed consent form to read. If they agree to participate, they will be asked to sign the consent form prior to participating.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Patient’s pretreatment pain, neurologic function (including facial numbness), and health related quality of life will be assessed.
