Recurrence of Trigeminal Neuralgia in Patient's Undergoing Radiofrequency Ablation

October 28, 2021 updated by: Muhammad Hasan Wasim, Shifa Clinical Research Center

Recurrence Rate of Trigeminal Neuralgia in Patients Treated With Percutaneous Stereotactic Continuous Radiofrequency Rhizotomy at 80 Degrees Celsius for 90 Seconds- a Single Center Study.

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.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
56

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

27 years to 91 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Sampling Method

Probability 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.

Description

Inclusion Criteria:

  • 1. 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:

  1. lasting from a fraction of a second to 2 minutes
  2. severe intensity
  3. 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.

2. Age: Adults of both sexes 3. MRI brain ruled out organic or structural pathologies

Exclusion Criteria:

  • 1. Patient with concomitant co-morbid conditions like brain tumours, vascular pathologies or coagulopathies.

    2. Patients who had previously undergone trigeminal ganglion neurolysis with either alcohol or phenol.

    3. 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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Recurrence rate of trigeminal neuralgia after stereotactic rhizotomy
Time Frame: Recurrence within 12 months of the intervention
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
Time Frame: 5 years
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

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
September 1, 2016

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
