Trial summary

Essential trigeminal neuralgia is the most common facial pain. In forms resistant to drug and disabling treatments, surgical treatment may be offered to the patient. The type of intervention will be conditioned by the presence or absence of a vasculo-nervous conflict objectified by MRI(Magnetic resonance imaging)… Read more about this study

About this study

Essential trigeminal neuralgia is the most common facial pain. In forms resistant to drug and disabling treatments, surgical treatment may be offered to the patient. The type of intervention will be conditioned by the presence or absence of a vasculo-nervous conflict objectified by MRI(Magnetic resonance imaging) Morphological MRI with contrast injection does not always allow an accurate assessment of trigeminal nerve damage in patients with essential facial neuralgia. Despite advances in the anatomical definition of high-resolution MRI, the correlation between a vascular conflict visible on MRI and present during surgery and prolonged postoperative clinical improvement remains insufficient These data raise the question of additional imaging sequences to assess the distressing characteristics of NT in addition to the usual anatomical criteria for compression By performing during morphological MRI two additional sequences, one in diffusion tensor (DTI) and one in resting state (fMRI), we could better characterize the achievement of NT

The contribution of new imaging sequences in the context of essential trigeminal neuralgia treated with microvascular decompression (MVD) would:

1/improve the diagnostic criteria for suffering and compression of the NT (trigeminal nerve) 2 / define objective prognostic criteria for the effectiveness of surgery, particularly in the context of unusual clinical symptoms or moderate conflict on MRI (Magnetic resonance imaging) 3 / to analyze more precisely the causes of recurrence at a distance from surgery and help in the decision of re-intervention Our main hypothesis: the addition of a diffusion tensor sequence and sequences (allowing functional brain analysis) in addition to standard anatomical MRI in the assessment of a vasculo-nervous conflict would allow us to better characterize involvement of the trigeminal nerve in essential facial neuralgia. It also helps guide therapeutic management and surgical indications.

This is a prospective, monocentric cohort study. It will be offered to patients referred to neurosurgery or to the pain assessment and treatment center for assessment and management of a neuralgia of the essential trijumeau unilateral.

Read the detailed description

Name:

MRI in morphological sequence, diffusion tensor and resting functional

Description:

The MR exam will be performed on the Neuroradiology 3 Tesla (Philips) MR according to the following protocol:

  • Standard anatomical sequences T1, FLAIR, TOF, DRIVE, sequence centered on the V after injection of gadolinated contrast product as part of standard care
  • Diffusion tensor sequence (DTI) It allows the analysis of encephalic white matter beams in healthy subjects as well as in many pathologies
  • resting state sequence (fMRI) This sequence is based on the spontaneous correlation of the BOLD signal (blood-oxygen level dependent) between different distant brain regions.
  • The total duration of the exam will be about 45 minutes, including 15 minutes for the sequences added by the search.

Questions about this trial

What is this clinical trial studying?

A study testing Assessment of the trigeminal nerve by diffusion tensor MRI and in "resting state" in the context of essential neuralgia in people with Trigeminal Neuralgia and Microvascular Decompression Surgery, run by Fondation Ophtalmologique Adolphe de Rothschild at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 11 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Assessment of micro-structural changes in the trigeminal nerve in essential neuralgia (time frame: Day 0 - inclusion). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Jun 2025.
