Introduction
Although Gasserian ganglion block is an established treatment for trigeminal neuralgia, the foramen ovale cannot always be
clearly visualized by classical X-ray radiography. We present a new method for percutaneous radio-frequency thermocoagulation
of the Gasserian ganglion, in which computed tomography (CT) fluoroscopy is used to guide needle placement.
Methods
In the present study, 15 patients with trigeminal neuralgia underwent percutaneous radio-frequency thermocoagulation of the
Gasserian ganglion guided by high-speed real-time CT fluoroscopy.
Results
Trigeminal neuralgia was improved in all patients after treatment without any severe complications. Moderate dysesthesia occurred
in only one case.
Conclusion
CT fluoroscopy-guided percutaneous radio-frequency thermocoagulation of the Gasserian ganglion was safe, quick, and effective
for patients with intractable idiopathic trigeminal neuralgia.
