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).
