Summary
Microvascular decompression surgery (MVDS) effectively treated trigeminal neuralgia in 92.5% of patients resistant to medication. This procedure offers a high success rate for long-term pain relief in suitable candidates.
Area of Science:
- Neurosurgery
- Neurology
Background:
- Trigeminal neuralgia (TN) is a debilitating neuropathic pain disorder.
- Medical management often fails for refractory TN cases.
Purpose of the Study:
- To prospectively evaluate the efficacy of microvascular decompression surgery (MVDS) for medically refractory trigeminal neuralgia.
- Assess long-term outcomes in patients undergoing MVDS.
Main Methods:
- Prospective study of 40 patients with TN undergoing MVDS between 2008-2010.
- Standardized follow-up using annual surveys and direct interviews.
- Surgical approach: lateral suboccipital in supine position.
Main Results:
- 37 out of 40 patients (92.5%) achieved complete pain relief post-surgery.
- Mean age of patients was 48 years (SD, 13).
- Etiology: idiopathic/vascular compression (39 patients), epidermoid tumor (1 patient).
Conclusions:
- MVDS is the treatment of choice for medically refractory trigeminal neuralgia.
- Pure MVDS demonstrates a high long-term cure rate (>98%) when significant vascular compression is identified.
- Supports MVDS as a definitive treatment for TN with clear vascular etiology.
