Trigeminal radiofrequency – Northern Italy
Specialist care for neuralgia and complex trigeminal pain
What is trigeminal nerve radiofrequency?
Trigeminal radiofrequency is an interventional procedure used in the treatment of selected forms of trigeminal pain, particularly when the pain is refractory to pharmacological therapies and correctly assessed from a diagnostic perspective.
The term encompasses different procedures in terms of anatomical target and delivery method. A treatment on a peripheral branch is not equivalent to an intervention on the Gasserian ganglion: indications, benefits, and risks must be discussed for the proposed technique.

When to consider radiofrequency
It is fundamental to clarify that trigeminal radiofrequency:
- is not a first-line therapy
- is not indicated for all facial pain
- requires accurate diagnosis and rigorous selection
In trigeminal neuralgia, carbamazepine and oxcarbazepine are the first-choice drugs. If control is insufficient or side effects limit their use, procedural and neurosurgical options are also discussed. In the classical form, microvascular decompression is the first recommended surgical option, when appropriate for the patient. EAN Guidelines.
Types of radiofrequency
The choice distinguishes the delivery method from the anatomical target. The two techniques are not interchangeable:
Pulsed radiofrequency
Delivers pulses interspersed with pauses, with the aim of modulating nerve activity and limiting the thermal effect. Its objectives differ from thermocoagulation and it carries possible risks: benefits and limitations must be assessed for the target and protocol used.
Thermal or lesional radiofrequency
Produces a controlled thermal lesion to reduce pain transmission. Percutaneous thermocoagulation at the level of the Gasserian ganglion is among the neuroablative options for neuralgia; it may involve a reduction in facial sensitivity.
Which trigeminal branches are treated?
Each division has specific anatomical and clinical characteristics. Choosing the target requires a clear diagnosis and individual planning.
Indications, procedural techniques and risks differ between V1, V2 and V3.
The care pathway before the procedure
Before considering trigeminal radiofrequency, the specialist path includes:
- In-depth clinical assessment
- Distinction between neuralgia, neuropathy, and other causes of persistent facial pain
- Review of clinical and therapeutic history
- Review of MRI and other available tests
- Possible selective diagnostic tests
The response to a block can provide information, but it does not confirm the diagnosis on its own nor does it guarantee the result of the radiofrequency. Bring reports, images, and the list of drugs tried with doses, benefits, and side effects to the visit. trigeminal assessment pathway.
Clinical experience dedicated to trigeminal pain
The interventional approach to the trigeminal nerve has represented a structured part of the clinical activity dedicated to craniofacial pain since 2012.
The experience gained over time allows for accurate selection of indications and personalised procedural planning based on the branch involved (V1, V2, V3).
Radiofrequency is not an automatic response to facial pain.
Medical care requires appropriate assessment and treatment; an individual outcome cannot be guaranteed.
Correct diagnostic definition represents the essential prerequisite for every therapeutic choice.
How radiofrequency is performed
- in a controlled environment
- under sterile conditions
- under fluoroscopic guidance
- with parameters selected based on the branch involved
The precision of positioning is a central element for the safety and efficacy of the procedure.
Risks and considerations
Like any interventional procedure, trigeminal radiofrequency also involves possible risks, which are assessed and discussed during the clinical path:
- numbness, tingling, or abnormal painful sensations in the treated area
- local pain, bleeding, or infection at the access point
- depending on the target: reduction of corneal sensitivity, masticatory weakness and, rarely, persistent pain in an insensitive area (anaesthesia dolorosa)
The risk/benefit assessment is an integral part of the indication.
Risks depend on technique and target. V1 requires particular attention to corneal sensitivity. Complications of ganglion procedures should not be attributed indiscriminately to all peripheral approaches. RCS Guidelines.
Expected benefits and limitations
In correctly selected patients, the procedure can result in:
- significant reduction in pain intensity
- decrease in the frequency of attacks
- improvement in quality of life
However, it is essential to clarify that:
- the response is not uniform
- pain may recur over time
- there are no guaranteed results
The result must be evaluated for the specific technique and diagnosis. During follow-ups, attacks, pain intensity, sensitivity, and daily activities are recorded. Any reduction in medication is agreed upon with the treating physician; a recurrence requires a re-evaluation before repeating the procedure.
When to re-evaluate the indication
- diagnosis still uncertain or persistent facial pain without a defined target
- central pain
- non-concordant clinical results, imaging, and tests: a negative block must be interpreted in context
- possible indication for microvascular decompression or other options to be discussed with the neurosurgeon
The term “atypical pain” alone does not constitute an indication for radiofrequency. The decision requires a defined diagnosis and a comparison between expected benefits, risks, and alternatives.
Clinical experience
The interventional management of trigeminal pain is handled by Dr Evangelos Panagiotakos MD within a rigorous and selective clinical pathway, developed over years of experience dedicated to complex craniofacial pain.

The path is also aimed at patients from Northern Italy with trigeminal neuralgia that is not adequately controlled or therapies that are poorly tolerated. The visit serves to verify the diagnosis and discuss the options suitable for the individual case.
