Trigeminal Neuralgia
Severe, electric-shock facial pain that can be triggered by everyday actions like chewing or brushing your teeth. When medication isn't enough, several procedural options can help bring relief.
Sudden, severe facial pain
Brief "electric shock" episodes, often triggered by light touch, chewing, talking, or brushing teeth.
Medication is first-line
Carbamazepine or oxcarbazepine often help, but some patients become refractory or can't tolerate side effects.
Procedural options available
Percutaneous procedures and stereotactic radiosurgery offer different paths to relief when medications fall short.
What is trigeminal neuralgia?
Trigeminal neuralgia (TN) is a condition that causes intense, sudden episodes of facial pain — often described as an electric shock. It's typically related to irritation of the trigeminal nerve, which carries sensation from the face to the brain.
Pain episodes can be disabling, but many patients respond well to a structured treatment pathway that begins with medication and progresses to procedural care when needed. The goal is always to find the approach that best balances pain relief with your tolerance for side effects.
Who may benefit from a procedure?
You may be a candidate if:
Most patients start with medication — procedures are considered when that's no longer sufficient.
-
✓Your symptoms fit the pattern of trigeminal neuralgia and you have tried appropriate medications — or cannot tolerate their side effects.
-
✓Your pain significantly impairs quality of life and you're looking for an option beyond medications.
Treatment Options
Each approach targets the trigeminal nerve differently. The choice involves balancing how quickly you want relief, your comfort with numbness, and whether you prefer an incisionless approach.
Radiofrequency Ablation
Percutaneous thermocoagulation of the trigeminal ganglion
Balloon Compression
Mechanical compression of the trigeminal ganglion
Stereotactic Radiosurgery
Focused radiation targeting the trigeminal nerve
Side-by-side comparison
Balancing speed of relief, invasiveness, and numbness risk.
| Feature | Radiofrequency | Balloon | Radiosurgery |
|---|---|---|---|
| Approach | Needle + heat | Needle + balloon | Focused radiation |
| Incision / needles | Needle (percutaneous) | Needle (percutaneous) | None |
| Anesthesia | Sedation (brief awake) | General anesthesia | Local only |
| Speed of relief | Often immediate | Often immediate | Gradual (weeks) |
| Numbness risk | Common / expected | Common / expected | Generally lower |
| Typical stay | Same day | Same day | Same day (outpatient) |
| Repeatable | Yes | Yes | Sometimes (with caution) |
What to Expect
All options begin with a thorough evaluation to confirm your diagnosis and match the right procedure to your goals.
Before your procedure
MRI review (often to assess neurovascular contact), medication review, and a discussion of your goals — including how you weigh fast relief versus an incisionless approach versus long-term durability.
During
Radiofrequency or balloon compression: Short procedural time, often same-day discharge.
Radiosurgery: Head immobilization under local anesthesia, outpatient treatment — no needles or incisions involved.
After
You'll track pain triggers and medication needs over the following weeks. Some patients are able to taper medications as pain control improves, guided by the clinical team. Follow-up visits focus on pain control, sensory exam, and your medication plan.
Benefits and Risks
Potential Benefits
- Meaningful pain reduction — often dramatic improvement
- Percutaneous procedures often act quickly
- Radiosurgery avoids needles and incisions entirely
- Potential to reduce or stop daily medications
Possible Risks
- Common: Facial numbness, transient jaw weakness, reduced corneal reflex
- Uncommon: Anesthesia dolorosa (painful numbness), corneal injury or keratitis, infection/bleeding, or delayed radiation injury (radiosurgery)
A note about corneal sensation
Some procedures can reduce corneal reflex (the protective blink response). If this occurs, eye protection strategies become important. Your team will discuss this before any procedure and monitor it during follow-up.

When to Seek Urgent Care
Seek urgent evaluation for new facial weakness, severe headache, fever, vision changes (especially if the eye feels dry or irritated after loss of corneal reflex), or confusion.
