Trigeminal Cistern Glycerol Injections for Facial Pain

Abstract

SYNOPSIS The treatment of paroxysmal facial pain is often easily accomplished. At times, however, the converse occurs; the pain becomes more refractory, and unresponsive to therapy. This is especially the case when trigeminal neuralgia, cluster headache, and atypical facial pain become chronic. This report will summarize our experience with injection of glycerol into the region of the trigeminal cistern for intractable facial pain in 71 patients; 58 with trigeminal neuralgia, 5 with chronic cluster headache, and 8 with atypical facial pain.
