With the Pulsed Radiofrequency treatment (PRF) Of the Gasserian ganglion for tRigeminal nEuralgia: a retroSpective Study (PROGRESS) the objective is to document the outcome of PRF (Pulsed Radiofrequency treatment) for patients with TN (Trigeminal Neuralgia), unresponsive to conservative treatment.
Primary objective: To determine the proportion of patients in which PRF (pulsed radiofrequency) of the Gasserian ganglion for trigeminal neuralgia (TN) provides acute pain relief of at least 50% on the GPE (Global perceived effect) score (six weeks after treatment) Secondary objectives: \- To determine the duration during which PRF of the Gasserian ganglion for trigeminal neuralgia provides a reduction of at least 50% on the GPE (Grade Point Equivalent) score.

GPE <50%
To determine the proportion of patients in which PRF (pulsed radiofrequency) of the Gasserian ganglion for trigeminal neuralgia (TN) provides acute pain relief of at least 50% on the GPE (Global perceived effect) score (six weeks after treatment)
Time frame: Six weeks after treatment
Duration of GPE <50%
To determine the duration during which PRF of the Gasserian ganglion for trigeminal neuralgia provides a reduction of at least 50% on the GPE (Grade Point Equivalent) score. This will be assessed six weeks post procedure and will be followed-up until definitive or possible relapse of neuralgia, assessed up to 48 months.
Time frame: From six weeks post procedure until definitive or possible relapse of neuralgia, assessed up to 48 months.
