Summary
Microvascular decompression (MVD) effectively treats trigeminal neuralgia (TN). This surgical approach offers significant pain relief for most patients, with no associated mortality, making it a recommended first-line treatment.
Area of Science:
- Neurosurgery
- Neurology
Background:
- Trigeminal neuralgia (TN) is a debilitating condition characterized by facial pain.
- Microvascular decompression (MVD) is a surgical option for TN.
- Factors influencing recurrence after MVD require further investigation.
Purpose of the Study:
- To present the experience with MVD for idiopathic TN.
- To identify factors associated with recurrence after MVD.
- To evaluate the efficacy and safety of MVD for TN.
Main Methods:
- Retrospective review of 90 patients with idiopathic TN who underwent MVD between 1986 and 2004.
- Exclusion of patients with atypical or secondary TN.
- Analysis of patient characteristics, surgical findings, and outcomes.
Main Results:
- Vascular compression of the trigeminal nerve was identified in 97% of patients.
- Arterial compression was more common (92%) than venous compression (8%).
- Complete symptom resolution occurred in 77 patients; partial relief in 10 patients. No improvement in 3 patients. No mortality was reported.
Conclusions:
- MVD is an effective and reliable treatment for trigeminal neuralgia.
- Vascular compression is the primary cause of TN in most cases.
- MVD is recommended as a first-line surgical treatment for medically refractory TN.
