Long term efficacy of microvascular decompression for trigeminal neuralgia

Objective: To evaluate the long term follow up efficacy and subjective satisfaction of microvascular decompression in 91 patients with trigeminal neuralgia who were followed up more than 1 year. Methods: Patients comprised 61 cases who underwent MVD between 1982 and 1992 in Yamagata University and 30 cases who underwent MVD between 1991 and 1996 in Ningxia Medical College. They were followed up from 13 to 126 months (mean 60 months), and follow up results were studied. Results: The immediate postoperative cure rate were 93 4%. Satisfactary results obtained by follow up were 80%. Incomplate pain relief were 6 6%. Recurrence pain rates were 15%. Occurred rates of postoperative hearing and facial sensory dysfunction were 7 7%. Conclusion: Improving immediate postoperative cure rate and decreasing complication ofter MVD by using improved techniques of MVD are important and feasible obtain satistfactory follow up results.
