Prognosis comparison of different branches of trigeminal neuralgia

Abstract Objective Exploring the remission rate of different branches of the trigeminal nerve after Microvascular decompression (MVD). Methods A retrospective analysis of Trigeminal neuralgia (TN) patients treated with MVD in our department from January 2014 to January 2015 was conducted to investigate the prognosis and factors affecting prognosis. Results 155 patients with TN, including 2 patients with V1 division, had a remission rate of 100.0% 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 were 91.7%, 87.5%, 75.0% and 66.7%; V2 division were 88.4%, 81.4%, 76.7% and 69.8%; V2-3 division were 90.2%, 90.2%, 87.8% and 75.6%; V3 division were 100.0%, 100.0%, 92.9% and 92.9%. Conclusions Postoperative remission rate of non-V2 related branches (V1, V3) is higher than V2 related branches (V2, V1-2, V1-3, V2-3).
