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.
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 modified Barrow Neurological Institute Pain Intensity Score
The efficacy of the treatment will be assessed using the modified Barrow Neurological Institute Pain Intensity Score (I: No pain, off medications; II: Occasional pain, off medications; IIIa: No pain, continued use of medications; IIIb: Pain persists, but adequately controlled with medications; IV: Pain not adequately controlled with medications; V: No relief).
Time frame: six months
Numeric rating scale
Pain will evaluated by a numerical rating scale (0 indicates no pain, 10 indicates the most severe pain imaginable).
Time frame: baseline to six months
Patient satisfaction
Patient satisfaction scores on the 5-point Likert scale (1: poor, 2: fair, 3: good, 4: very good, 5: excellent)
Time frame: six months
