Case report: computed tomography scan-guided Gasserian ganglion injection of dexamethasone and lidocaine for the treatment of recalcitrant pain associated with herpes simplex type 1 infection of the ophthalmic division of the trigeminal nerve.

Abstract

We describe the case of a 17-year-old boy with dermatologic herpes simplex virus-1 outbreaks with incapacitating facial pain requiring multiple hospitalizations. He failed to respond to aggressive treatments including antiviral drugs, opioid analgesics, stellate ganglion, and supraorbital and supratrochlear nerve blocks. The patient elected to undergo dexamethasone and lidocaine Gasserian ganglion block under computed tomography-scan guidance. He had immediate and complete relief of his pain for the first time in almost 2 years. The patient remained pain free during 6-month follow-up visits. This is the first reported use of Gasserian ganglion block for treatment of herpes simplex virus-1 infection of the trigeminal nerve.
