Trigeminal neuralgia (TN) is defined as sudden, severe, short-term, stabbing and recurrent pain in the distribution of one or more branches of the trigeminal nerve. Many invasive treatments are available for patients who respond poorly to medical therapy. Among them, radiofrequency therapy is a viable option with a reliable initial and long-term clinical efficacy.
The aim of this study is to compare the efficacy of radiofrequency of the Gasserian ganglion versus peripheral branches of the trigeminal nerve for the treatment of trigeminal neuralgia.
