Abstract：Objective To explore the factors related to the recurrence of primary trigeminal neuralgia (PTN) after microvascular decompression (MVD).Methods The clinical data of 164 patients with PTN who underwent MVD in department of neurosurgery of our hospital from January,2014 to January,2017 were analyzed retrospectively.The factors related to the recurrence were statistically analyzed in the patients.Results The facial pain belonged in gradesⅠ～Ⅱin 139 patients (84.76%) and gradesⅢ25 (15.24%) 1 weeks after MVD according to Barow Neurological Institute pain grade.There were the postoperative complications including facial numbers,herps of corners of the mouths,hearing disturbance and taste deficiency in 11 patients.The trigeminal recurred 12～48 months after MVD in 31 patients.Multivariable Logistic regression analysis showed that the independent risk factors related to the recurrence included the disease duration≥5 years,insufficient decompression,and displacement of compression in patients with PTN (P＜0.05).Conclusions The curative effect of MVD on PTN and its safety are good.It is necessary to pay high attention to the risk factors related to the recurrence in the patients with PTN.
