Radiofrequency trigeminal rhizotomy in treatment of symptomatic non-neoplastic facial pain

Research output: Contribution to journalArticlepeer-review


Twenty patients suffering from non-neoplastic symptomatic facial pain underwent percutaneous radiofrequency trigeminal thermo-rhizotomy. Fourteen patients had long-standing severe multiple sclerosis, two patients had intracranial aneurysms, three patients had basilar impression secondary to Paget's disease and developmental malformation of the skull, and one patient was suffering from chronic ocular pain that developed after retinal hemorrhage. Pain paroxysms similar to tic douloureux were present in patients with multiple sclerosis and in those with basilar impression, while continuous aching pain was present in the others. After thermo-rhizotomy, pain disappeared in all patients; however, at 1 to 4 years follow-up examination, a high recurrence rate (40%) was present in the multiple sclerosis group, and the percutaneous procedure was successfully repeated. In the patients with intracranial aneurysm not amenable to direct surgery, and in the other non-neoplastic diseases, complete pain relief was found at 4 years follow-up review.
