Abstract：Objective To investigate the risk factors for recurrence of trigeminal neuralgia after fully endoscopic microvascular decompression.Methods The clinical data of 104 patients with trigeminal neuralgia treated with fully endoscopic microvascular decompression from February 2020 to January 2024 were retrospectively analyzed.Postoperative follow-up was conducted for 1 year,recurrence were assessed according to the Barrow Neurological Institute(BNI)Pain Intensity Scale.Results Immediate postoperative pain was completely relieved in 103 cases(99.04%);complications occurred in 4 cases(2.70%).During the 1-year postoperative follow-up,recurrence was observed in 11 cases(10.58%).Multivariate logistic regression analysis showed that poor response to analgesic drugs,atypical clinical symptoms,non-arterial compression,and a cerebellopontine angle area ratio(healthy/affected side)>1 were independent risk factors for recurrence of trigeminal neuralgia after fully endoscopic microvascular decompression(P<0.05).Conclusion Fully endoscopic microvascular decompression is an effective method for treating trigeminal neuralgia.Patients with poor response to analgesic drugs,atypical clinical symptoms,non-arterial compression,and a cerebellopontine angle area ratio(healthy/affected side)>1 have an increased risk of postoperative recurrence.
