Comparison of Two Types of Radiofrequency Treatment for Trigeminal Neuralgia

Conventional RFA was performed at the Gasserian ganglion under fluoroscopic guidance with thermal lesioning at 70-75°C for up to 90 seconds. Sensory and motor stimulation were used to verify needle placement.

PRF was applied to the peripheral branch of the trigeminal nerve at 42°C for two cycles of 120 seconds using fluoroscopic guidance. This technique was preferred in our clinic to avoid thermal complications such as hypoesthesia or motor dysfunction.
