title: Retrogasserian glycerol injection or percutaneous stimulation in the treatment of typical and atypical trigeminal pain.
abstract: Of 164 patients with trigeminal neuralgia treated by percutaneous retrogasserian glycerol injections, we have studied the long-term outcome (one to four years) of 72 patients. 51 patients suffered from idiopathic trigeminal neuralgia, and of these 92% were freed from pain by the operation. 21 patients suffered from symptomatic trigeminal neuralgia due to multiple sclerosis or of traumatic or infectious origin. Of these, only 38% became free of pain. A further 8 patients with facial deafferentation pain who underwent treatment by retrogasserian neurostimulation with a permanently implanted electrode were included in this study. 4 of these patients were rendered free of pain by this procedure.
