Summary
To investigate the brain activations related to TN, using fMRI, and to evaluate changes in these activations following the application of pulsed and thermal Radiofrequency lesioning to the gasserien ganglion.
Conditions
Interventions
| Type | Name | Description |
|---|---|---|
| PROCEDURE | pulsed Radiofrequency | sensory stimulation will be carried out at 50 Hz. The definitive position of the electrode will be verified by inducing paresthesia with sensory stimulation between 0.1-0.3 V in the affected painful area, then pulsed radiofrequency will be applied for 10 patients for 10 mins |
| PROCEDURE | thermal Radiofrequency | sensory stimulation will be carried out at 50 Hz. The definitive position of the electrode will be verified by inducing paresthesia with sensory stimulation between 0.1-0.3 V in the affected painful area, then Thermal lesion will be applied for 10 patients for 2 cycles of 90 seconds |
