Objective:
This study aims to share a single surgeon's experience among patients with primary and secondary trigeminal neuralgia (TGN) managed with microvascular decompression (MVD), detailing immediate and last follow-up results and identifying the prognostic factors associated with various outcomes and recurrences.
Methods:
A retrospective observational analysis of 136 consecutive patients (78.2% primary, 21.8% secondary TGN) managed with MVD between June 2018 and January 2025, with at least 3 months of follow-up, was conducted. Surgical results, complications, and recurrence rates were reviewed along with factors affecting these outcomes.
Results:
A total of 101 patients were analyzed with a mean preoperative duration of symptoms of 4 years. V2V3 segment was the most common pain-harboring region. Superior cerebellar artery was the most common conflicting vessel. Immediate complete pain relief was achieved in 94.8% of cases (94.7% in primary and 95.2% in secondary TGN groups). At a mean latest follow-up of 266 (range: 10-2250 days) days, 84.2% of primary TGN and 95.2% of secondary TGN patients had experienced persistent pain relief (Barrow Neurological Institute [BNI] I). Poor immediate pain relief correlated strongly with poor outcomes at both first and final follow-up (P < 0.001). The most frequent complication was facial hypoesthesia (19.6%). The recurrence rate at last follow-up was 31.6%. Redo MVD stood out as the most efficient treatment modality.
Conclusion:
MVD still enjoys being the most coherent management strategy for drug-resistant TGN, with age being no bar. Favorable outcomes with shorter preoperative duration prompt the need for increasing patient awareness, improving multidisciplinary communications, and expeditious referral to a neurosurgical unit to amplify the patient's welfare. A duration of preoperative symptoms of more than 4 years, >2 vessels in conflict, and lack of immediate postoperative relief in symptoms herald the increased risk of pain recurrence.
