Summary
Repeat microvascular decompression (MVD) offers a viable treatment for recurrent trigeminal neuralgia (TN), with 67% success. Older age and immediate pain relief are key success factors, and complications like facial numbness can be minimized.
Area of Science:
- Neurosurgery
- Neurology
Background:
- Microvascular decompression (MVD) is the primary treatment for medically refractory idiopathic trigeminal neuralgia (TN).
- The efficacy and safety of repeat MVD for recurrent TN remain less established.
Purpose of the Study:
- To evaluate the outcomes, risk factors, and complication rates of repeat MVD in patients with recurrent TN.
- To assess the feasibility of repeat MVD as a therapeutic option for trigeminal neuralgia.
Main Methods:
- A retrospective chart review and telephone interviews were conducted for 33 patients who underwent repeat MVD between 1990 and 2012.
- Risk factors for success were analyzed using binary logistic regression.
Main Results:
- 67% of repeat MVD procedures were successful at 12-month follow-up, with 19 patients achieving complete pain relief without medication.
- Older age and immediate post-operative pain relief were significant predictors of success.
- Facial numbness occurred in 27% of patients, with minimal other morbidity and no mortality.
Conclusions:
- Repeat MVD is a feasible and effective treatment for recurrent TN, even after prior neurodestructive procedures.
- Careful surgical technique, including limited neurolysis, can minimize complications such as facial numbness.
