| II Objective I evaluate the long-term efficacy in 23 patients who underwent microvascular decompression for trigeminal neuralgia. I method] Between 1992-2000ys, 51 patients with trigeminal neuralgia underwent microvascular decompression at the first affiliated hospital of XingJiang medical university. The results were studied to verify efficacy of microvascular decompression in 23 of 33 patients who participated in follow-up evaluation postoperatively. The follow-up period ranged from 5 to 91 months (mean 30.9 ins). [Result] The immediate postoperative cure rate was 95.6%(n22). Incomplete pain relief was 4.40/o(n1). Recurrence pain rate was 8.3 0%(n=2). Both of them occurred in the first year after operation. 18 Occurred rate of serious complication was 17.40/o(n4). Satisfactory results obtained by follow-up were 83.O%(n19). [conclusion] Microvascular decompression is the optimal surgical technique for treatment of trigeminal neuralgia. Improved methods of repositioning the affected vessels and of straighting the axis of the trigeminal nerve are important to obtain satisfactory follow-up results after microvascular decompression. |
