The goal of this observational study is to learn about the long-term effects of microvascular decompression (MVD) in patients with trigeminal neuralgia (TN). The main question it aims to answer is:

Does undergoing post-operative dental treatment or other orofacial stimulation increase the likelihood of pain relapse after MVD for TN?

Participants who have previously undergone MVD for TN as part of their standard medical care will be asked to complete surveys over phone call. These surveys will focus on their pain experiences, timing, anxiety attacks and nature of any pain relapses, and whether they have received dental treatments or other orofacial interventions during follow-up.

Inclusion Criteria:

• MVD post-operative patients with type I Trigeminal Neuralgia.

Exclusion Criteria:

• Atypical (Type II) Facial Pain at presentation, revision surgery.
• Patients who are unable or unwilling to provide informed consent will be excluded from the study.

Potential participants will be identified through a review of the post-operative patient database at Robert Wood Johnson University Hospital in New Brunswick, New Jersey. Eligible subjects are individuals who have undergone initial microvascular decompression (MVD) surgery for trigeminal neuralgia. Medical records will be accessed through the EPIC system, with IRB approval in place
