Post-Operative Trigeminal Pain After Microvascular Decompression for Trigeminal Neuralgia

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.
