Identifying the Trigeminal Nerve Branches for Transovale Radiofrequency Thermolesion

Abstract

This method proved to be useful to determine the exact localization of individual subdivisions of the trigeminal nerve in anesthetized patients, making this procedure safer and more comfortable for them.

A Prospective Study of X-Ray Imaging Combined with Skin Stimulation Potential-Guided Percutaneous Radiofrequency Thermocoagulation of the Gasserian Ganglion for Treatment of Trigeminal Neuralgia

“…Percutaneous radiofrequency coagulation of the Gasserian ganglion is widely accepted worldwide as a minimally invasive technique for treatment of primary trigeminal neuralgia. However, the understanding and mastery of surgical details varies among different hospitals [13]. To establish and standardize an operation procedure that is efficacious, controllable, safe, and low cost are key tasks for clinical physicians.…”

CT-Guided Percutaneous Infrazygomatic Radiofrequency Neurolysis Through Foramen Rotundum to Treat V2 Trigeminal Neuralgia

“…Numerous technological advances have been described to improve correct positioning of the needle for safer therapy, including transition from fluoroscopy to computed tomography (CT) guidance, three‐dimensional (3D) navigation techniques, and electrophysiological recordings including evoked potential confirmations [12–15]. Here we report a novel CT‐guided technique to block the V2 branch via a trans‐FR approach.…”

Application of MRI and intraoperative CT fusion images with integrated neuronavigation in percutaneous radiofrequency trigeminal rhizotomy

“…Some authors have proposed another method of functional localization with an antidromic conduction to localize the target, but the technique was done for patients under general anesthesia [4]. Previous cadaveric studies revealed a safe puncture depth of 6-10 mm above the foramen ovale [2,6,8].…”
