摘要
The results of the treatment of trigeminal neuralgia by neurovascular decompression or partial sensory rhizotomy in a personal series of 220 patients are presented. Microvascular decompression was performed in 178 patients and partial sensory rhizotomy in 42. The mean follow-up was 5.2 years. Immediate pain relief was achieved in 94% of all patients, but the rate dropped to 84% during the follow-up period. The recurrence rate in the microvascular decompression group was 6% and in the PSR 49%. Permanent sequelae occurred in 4 patients (loss of hearing 1; loss of corneal reflex, 1; lesion of the portio minor, 2), but transitory complications (impaired hearing caused by hematotympanum and diplopia) were more frequent, especially in the beginning of the series. Elderly patients tolerated the procedure very well and the percentage of complications was evenly distributed in all age groups. Three patients died. No patient developed painful dysesthesias or anesthesia dolorosa. There were no differences in the outcome, considering sex and age. The duration of symptoms did not influence the prognosis. Patients with severe compression did better than those with a mild one, and patients with an arterial compression did better than those with a venous one. Trigeminal neuralgia in multiple sclerosis is seldom relieved by microvascular decompression. The experience of the surgeon reduces the number of negative findings considerably.
