Abstract:

Objective    To explore the method and effectiveness of micro-vascular decompression(MVD) on the treatment of primary trigeminal neuralgia(TN). Methods    MVD was carried out on 142 primary TN patients, and the data were retrospectively analyzed. Results     Of all cases, total pain relief was achieved in 128 (90%), partial pain relief in 9, and a total of 137(96.5%) profited from MVD. In the 82 cases with a more than 2-year follow-up, pain vanished in 74, pain sometimes occurred in 5, which could be relieved by oral medicine (carbamazepine), and the remaining 3 could not be effectively controlled by medicine. Conclusions    MVD is an effective method in treating primary TN. Finding responsible vessels exactly and handling properly are the key to MVD. Skilled manipulation could lower the probability of mortality and complications to the greatest degree.
