Summary
Microvascular decompression (MVD) for trigeminal neuralgia (TN) offers long-term pain relief for many patients. Recurrence is uncommon after 5 pain-free years, with most relapses occurring within 2 years post-operation.
Area of Science:
- Neurosurgery
- Neurology
- Pain Management
Background:
- Trigeminal neuralgia (TN) is a debilitating neuropathic pain condition.
- Microvascular decompression (MVD) is a surgical treatment for TN.
- Long-term recurrence rates after MVD for TN require further investigation.
Purpose of the Study:
- To determine the incidence and timing of recurrent trigeminal neuralgia (TN) after posterior fossa microvascular decompression (MVD).
- To identify factors associated with TN recurrence following MVD.
Main Methods:
- Prospective follow-up of 133 patients who underwent MVD for TN.
- Follow-up duration ranged from 6 months to 15 years.
- Analysis of recurrence rates and associated clinical/operative factors.
Main Results:
- 71% of patients remained pain-free long-term.
- 29% experienced recurrence, with 90% occurring within 2 years.
- No recurrence was observed in patients pain-free for 5 years post-MVD.
- Recurrence was linked to non-compressive findings and younger age at onset (<35 years).
Conclusions:
- MVD provides durable pain relief for a majority of trigeminal neuralgia patients.
- The risk of recurrence significantly decreases after 5 pain-free years.
- Identifying specific operative findings and patient demographics can help predict recurrence risk.
