Prognosis Comparison of Different Branches of Trigeminal Neuralgia.

OBJECTIVE

We explored the remission rate of different branches of the trigeminal nerve after microvascular decompression.

METHODS

A retrospective analysis of trigeminal neuralgia patients treated with microvascular decompression in our department from January 2014 to January 2015 was conducted to investigate the prognosis and factors affecting prognosis.

RESULTS

One-hundred and fifty-five patients with trigeminal neuralgia including 2 patients with V1 division had a remission rate of 100% at 1 day, 3 months, 1 year, and 3 years after surgery; 93.5%, 93.5%, 90.3%, and 67.7% of patients with V1-2 division. The patients with V1-3 division had rates of 91.7%, 87.5%, 75.0%, and 66.7%; V2 division rates were 88.4%, 81.4%, 76.7%, and 69.8%; V2-3 division rates were 90.2%, 90.2%, 87.8%, and 75.6%; and V3 division were 100%, 100%, 92.9%, and 92.9%.

CONCLUSIONS

Postoperative remission rate of non-V2-related branches (V1, V3) are higher than V2-related branches (V2, V1-2, V1-3, V2-3).
