Comparison of microvascular decompression and percutaneous balloon compression efficacy in patients with V2 idiopathic trigeminal neuralgia

This study aims to compare the efficacy and long-term prognosis of microvascular decompression (MVD) versus percutaneous balloon compression (PBC) in patients with idiopathic V2 (maxillary branch) trigeminal neuralgia. We retrospectively analyzed the clinical information and follow-up data of patients who underwent surgical treatment for V2 idiopathic trigeminal neuralgia from January 2020 to January 2023. A total of 58 patients were included in the MVD group and 99 in the PBC group. All surgeries were performed by two physicians at the same center, with follow-up conducted by a separate, trained researcher. We compared the initial versus 12-month postoperative pain relief rates (scored using the BNI), surgical complications, and described pain relief rates after long-term follow-up in both groups using Kaplan-Meier analysis. The study included a total of 157 patients (MVD 58, PBC 99). The median age of patients in the MVD group was lower than that in the PBC group (58 [51-65] vs. 63 [58-69], = 0.002). There was no significant difference between the two groups in terms of pain relief rates initially after surgery and at 12 months ( = 0.521, = 0.713). However, the MVD group had significantly better outcomes regarding postoperative facial numbness (
