Purpose
Trigeminal neuralgia or tic douloureux is severe, often debilitating, facial pain that significantly impairs the patient's quality of life and health. Stereotactic radiosurgery has been shown to provide pain relief in majority of patients treated. However, a common side effect of radiosurgery is facial numbness. To better understand how radiosurgery can bring about pain relief and facial numbness, we are conducting a study in which brain MRI scans will be done following stereotactic radiosurgery to learn if there are any changes in the MRI scans that correlate with symptoms.

Study Population
All patients age 18 years and older with typical trigeminal neuralgia, as determined by diagnostic criteria set by the International Headache Society, who was treated with SRS.
Criteria
Inclusion Criteria:
- All patients age 18 years and older with typical trigeminal neuralgia, as determined by diagnostic criteria set by the International Headache Society, who are 1) intolerant of or refractory to medical management and 2) not candidates for or refusing a surgical micro-vascular decompression, will be evaluated for treatment with SRS.
- ECOG or Karnofsky Performance Status will not be employed, but patients must be sufficiently healthy to tolerate all study procedures.
- Patient must exhibit the ability to understand and the willingness to sign a written informed consent.
Exclusion Criteria:
- Exclusion criteria
- Patients who present with pre-existing facial numbness.
- Patients MRI contraindications (e.g., pacemaker or defibrillator, cochlear implant, brain aneurysm clip, etc.)
- Patients who have previously been treated with MVD.
- Patients who have previously had an ablative treatment, including prior SRS.
- Pediatric patients (age <18), pregnant women, and patients who are unable to give informed consent will be excluded.
