NCT05101577

Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

  • 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

Sampling MethodProbability Sample
Study Population

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.

You may qualify if:

  • \. Patients fulfilling ICHD criteria:
  • Recurrent paroxysms of unilateral facial pain in the distribution(s) of one or more divisions of the trigeminal nerve, with no radiation beyond, and fulfilling criteria B and C
  • A. Pain has all of the following characteristics:
  • lasting from a fraction of a second to 2 minutes
  • severe intensity
  • electric shock-like, shooting, stabbing or sharp in quality B. Precipitated by innocuous stimuli within the affected trigeminal distribution C. Not better accounted for by another ICHD-3 diagnosis.
  • \. Age: Adults of both sexes 3. MRI brain ruled out organic or structural pathologies

You may not qualify if:

  • \. Patient with concomitant co-morbid conditions like brain tumours, vascular pathologies or coagulopathies.
  • \. Patients who had previously undergone trigeminal ganglion neurolysis with either alcohol or phenol.
  • \. Patients who were lost to follow-up before the completion of 6-month period or had not visited back after the procedure 4. Patients on oral anticoagulants 5. Patients declared high risk or ASA 3 and above for general anaesthesia.
