Microvascular decompression for trigeminal neuralgia outcome

Microvascular decompression (MVD) is the most effective long-term surgical treatment for trigeminal neuralgia (TN) patients. The risk factors for poor pain control following MVD surgery are not fully understood.

Younger patients with TN had worse long-term pain outcomes following MVD. Additional factors associated with postoperative recurrence included poor preoperative pain control (BNI score > IV) and multivessel compression. Furthermore, SCA combined with PV was confirmed to be associated with a worse outcome 1).


Not all patients with TN manifest unequivocal neurovascular compression (NVC). Furthermore, over time patients with an initially successful MVD manifest a relentless rate of TN recurrence.

It does not achieve 100 % cure rate. Re-exploration of the posterior fossa may carry increased risk over first-time MVD and is not always successful, so other treatments are needed.


Age itself does not seem to represent a major contraindication of microvascular decompression for typical trigeminal neuralgia 2).

Patients 60 yr of age and older have significantly better long-term pain outcomes following MVD than younger patients 3).
