About this study
Official title: A Prospective, Randomized Comparison of the Radiofrequency of Gasserian Ganglion Versus Peripheral Branches of the Trigeminal Nerve for the Treatment of Trigeminal Neuralgia.
The aim of this study is to compare the efficacy of radiofrequency of the Gasserian ganglion versus peripheral branches of the trigeminal nerve for the treatment of trigeminal neuralgia.
Read the detailed description
Trigeminal neuralgia (TN) is defined as sudden, severe, short-term, stabbing and recurrent pain in the distribution of one or more branches of the trigeminal nerve. Many invasive treatments are available for patients who respond poorly to medical therapy. Among them, radiofrequency therapy is a viable option with a reliable initial and long-term clinical efficacy.
- Conditions
- Trigeminal Neuralgia
- Being tested
- radiofrequency of gasserian ganglion, radiofrequency of the peripheral trigeminal branches
- Medical subject headings
- Trigeminal Neuralgia
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
radiofrequency of gasserian ganglionProcedure or surgery
radiofrequency ablation of the gasserian ganglion
radiofrequency of the peripheral trigeminal branchesProcedure or surgery
radiofrequency of the peripheral trigeminal branches ( maxillary, mandibular, supraorbital)
| Study group | Role | What they receive |
|---|---|---|
| Radiofrequency of peripheral branches of the trigeminal nerve | Experimental | pulsed radiofrequency treatment of the peripheral branches of the trigeminal nerve Receives: Procedure: radiofrequency of the peripheral trigeminal branches |
| Radiofrequency of gasserian ganglion | Active comparator | radiofrequency ablation of the gasserian ganglion Receives: Procedure: radiofrequency of gasserian ganglion |
What is being measured
The primary outcome is the main question the study is designed to answer.
The modified Barrow Neurological Institute Pain Intensity Score
The efficacy of the treatment will be assessed using the modified Barrow Neurological Institute Pain Intensity Score (I: No pain, off medications; II: Occasional pain, off medications; IIIa: No pain, continued use of medications; IIIb: Pain persists, but adequately controlled with medications; IV: Pain not adequately controlled with medications; V: No relief).
Measured: six months
Secondary outcomes (2)
Numeric rating scale
Pain will evaluated by a numerical rating scale (0 indicates no pain, 10 indicates the most severe pain imaginable).
Measured: baseline to six months
Patient satisfaction
Patient satisfaction scores on the 5-point Likert scale (1: poor, 2: fair, 3: good, 4: very good, 5: excellent)
Measured: six months

Questions about this trial
What is this clinical trial studying?
A study testing radiofrequency of gasserian ganglion and radiofrequency of the peripheral trigeminal branches in people with Trigeminal Neuralgia, run by Diskapi Teaching and Research Hospital at 1 site in Turkey (Türkiye).
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 3 inclusion and 4 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: finished, as of the sponsor's last update on 6 Sep 2023. 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 Turkey (Türkiye). 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The modified Barrow Neurological Institute Pain Intensity Score (time frame: six months). 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 6 Sep 2023; AzTrials last refreshed its copy on 8 Nov 2026.
