Aim: Prognostic factors detection and analysis of long-term results of microvascular decompression for trigeminal neuralgia. Materials and methods.  161 cases of trigeminal neuralgia (TN) treatment by MVD technique without preliminary invasive interventions within 10 years were analyzed. Two blocks of information were designed which included objective case data (8 factors) and patient satisfaction survey (5 questions). Follow-up minimal cut-off was 1 year (median 5.8 years). The primary end point is the proportion of pain free patients and BNI (Barrow Neurological Institute) score at last follow-up. The secondary end point is the assessment of possible risk factors of  treatment failure: symptoms duration, decompression type, affected nerve branches, neurovascular conflict visible on MRI, different indications for surgery. Logit-regression analysis was carried out. Significance level was set at p
