Actual (reported)This study aims to find recurrence rate of the trigeminal neuralgia after patients undergo stereotactic rhizotomy by radiofrequency ablation at 80 degrees Celsius for 90 seconds under fluoroscopic guidance, a protocol that was modified from the originally described parameters for rhizotomy by John Tew, Chad J. Morgan and Andresw Grande et al. The presumption being that the higher temperature of the probe tip would lead to a more long-lasting lesion and lesser recurrence, but at the cost of more frequent sensory and motor deficits.

Actual (reported)Recurrence rate of trigeminal neuralgia after stereotactic rhizotomy
Recurrence of pain in the same distribution of the trigeminal nerve branch or branches for which the stereotactic rhizotomy was originally performed
Recurrence within 12 months of the intervention
Proportion of patients with neurological deficits after stereotactic rhizotomy
locally deviced protocol for stereotactic rhizotomy of the involved trigeminal gangion dictates the use of higher temperature of 80 degree Celsius for 90 seconds, which translates into better pain relief and longer pain free intervals at the cost of higher percentage of sensory and motor deficits

Adult patients of all genders presenting to Pain Clinic, referred of otherwise, diagnosed to have trigeminal neuralgia without concomitant central nervous pathologies including space occupying lesions, vascular and auto-immune disorders, who were planned for stereotactic rhizotomy under deep sedation and monitored anesthesia care as daycare cases.
