Summary
Microvascular decompression (MVD) for trigeminal neuralgia (TN) offers long-term pain relief for many. Recurrence is possible, especially within two years post-operation, but unlikely after five pain-free years.
Area of Science:
- Neurosurgery
- Neurology
- Pain Management
Background:
- Trigeminal neuralgia (TN) is a debilitating condition characterized by facial pain.
- Microvascular decompression (MVD) is a surgical treatment option for TN.
- Understanding the long-term efficacy and recurrence rates of MVD is crucial for patient management.
Purpose of the Study:
- To prospectively determine the incidence 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.
- Data collected on pain recurrence, time to recurrence, and operative findings.
Main Results:
- 71% of patients remained pain-free long-term.
- 29% experienced major or minor recurrence of TN.
- 90% of recurrences occurred within 2 years; no recurrences were observed after 5 pain-free years.
- Recurrence was more likely with non-compressive operative findings and onset age < 35 years.
Conclusions:
- MVD provides durable pain relief for a majority of trigeminal neuralgia patients.
- Early recurrence is the norm, with a plateau of pain freedom observed after 5 years.
- Identifying patients at higher risk for recurrence can aid in surgical decision-making and follow-up strategies.
