Randomized Controlled Trial
Ultrasound guidance combined with C-arm fluoroscopy in selective semilunar ganglion radiofrequency thermocoagulation through foramen ovale for trigeminal neuralgia: A randomized controlled trial.
To explore the clinical value of ultrasound guidance combined with C-arm guidance during selective semilunar ganglion radiofrequency thermocoagulation via the foramen ovale for trigeminal neuralgia. ⋯ Ultrasound guidance combined with C-arm guidance could be safely used for puncturing the semilunar ganglion via the foramen ovale, with more efficiency and less radiation exposure than C-arm guidance alone.
