Trigeminal neuralgia treatment

Understand trigeminal neuralgia treatment options, from medication to specialist procedures.

What is trigeminal neuralgia treatment?

Trigeminal neuralgia treatment focuses on managing facial pain and reducing its impact on daily life. Medication is usually the first treatment offered and can be effective for many people.

If pain is not well controlled with medication, or side effects become difficult to manage, other treatment options include microvascular decompression, procedures that target the trigeminal nerve, and stereotactic radiosurgery using Gamma Knife.

Treatment options will vary from person to person and may depend on the cause of trigeminal neuralgia, symptoms, overall health and response to previous treatments.

Medication for trigeminal neuralgia

Medication is generally the first treatment used to manage trigeminal neuralgia.

Standard pain relief medicines such as paracetamol are usually not effective. Instead, medicines that reduce the transmission of nerve signals are prescribed most often, including:

Carbamazepine – commonly used as a first-line treatment
Oxcarbazepine – may be used as an alternative
Other medicines – including lamotrigine, gabapentin, pregabalin and baclofen, depending on individual circumstances

Medication can provide effective pain relief, particularly when treatment first begins. However, its effectiveness may change over time, and some people experience side effects such as drowsiness, dizziness or difficulty concentrating.

If pain is no longer adequately controlled or medication is causing difficult side effects, a specialist may discuss other treatment options.

Do not change or stop medication for trigeminal neuralgia without speaking to a healthcare professional.

Microvascular decompression for trigeminal neuralgia

Microvascular decompression (MVD) is a surgical procedure used to treat trigeminal neuralgia when a blood vessel is compressing the trigeminal nerve.

During the procedure, a neurosurgeon accesses the nerve through an opening in the skull and carefully separates the blood vessel from the nerve. A small piece of material may be placed between them to prevent further contact.

Unlike treatments that intentionally affect the function of the trigeminal nerve, MVD aims to address the underlying compression while preserving the nerve.

MVD can provide long-term pain relief for some people, particularly where imaging shows a blood vessel compressing the trigeminal nerve. However, it’s a major operation performed under general anaesthetic and has associated surgical risks.

A neurosurgeon can discuss whether MVD may be suitable based on the cause of the trigeminal neuralgia, general health and other individual factors.

Percutaneous procedures for trigeminal neuralgia

Percutaneous procedures are minimally invasive treatments that deliberately affect part of the trigeminal nerve to interrupt the transmission of pain signals to the brain.

A needle or thin tube is passed through the cheek towards the trigeminal nerve. The procedure is usually performed under sedation or general anaesthetic, and imaging is used to help guide treatment.

Types of percutaneous procedures include:

Radiofrequency lesioning – uses controlled heat to affect selected nerve fibres
Balloon compression – uses a small balloon to compress part of the trigeminal nerve
Glycerol injection – uses glycerol to affect the nerve and disrupt pain signals

These procedures can provide pain relief, although pain may return over time. Because they deliberately affect the trigeminal nerve, facial numbness or altered sensation can occur following treatment.

Gamma Knife radiosurgery for trigeminal neuralgia

Gamma Knife radiosurgery is a non-invasive treatment that uses highly focused beams of radiation to target a small area of the trigeminal nerve.

Despite its name, Gamma Knife doesn’t involve a knife or surgical incision. Multiple beams of radiation are precisely focused on the nerve while limiting radiation exposure to surrounding areas.

For trigeminal neuralgia, Gamma Knife treatment aims to disrupt the transmission of pain signals along the trigeminal nerve.

Gamma Knife radiosurgery may be considered when:

medication is no longer adequately controlling pain
medication is causing difficult or unacceptable side effects
other treatments have not provided sufficient pain relief
surgery is not suitable or not preferred
a non-invasive treatment option is preferred

Suitability for Gamma Knife radiosurgery is assessed by a specialist team and depends on individual circumstances.

What happens during Gamma Knife treatment?

A specialised head frame is typically fitted to help keep your head in a precise position during imaging and treatment. Detailed imaging, such as an MRI, is then taken to help plan your treatment.
Your treatment team uses the images to carefully plan the area of the trigeminal nerve to be treated and where the radiation will be delivered.
The Gamma Knife machine delivers multiple highly focused beams of radiation to the targeted area of the trigeminal nerve. No incision is required, and treatment is typically completed in a single session.

What happens after Gamma Knife radiosurgery?

Pain relief following Gamma Knife radiosurgery is not usually immediate. It may take several weeks or longer for the treatment to take effect.

Medication may therefore need to continue for a period following treatment. Any changes to medication should be discussed with the treating specialist.

Follow-up appointments are used to monitor pain relief, medication requirements and any side effects.

Some people may experience facial numbness or altered sensation following Gamma Knife treatment. The specialist team will discuss the potential benefits and risks before treatment.

Which trigeminal neuralgia treatment is right for me?

There is no single treatment that is appropriate for everyone with trigeminal neuralgia.

The treatment recommended will depend on factors including:

the type and underlying cause of trigeminal neuralgia
the severity and frequency of pain
how well medication is controlling symptoms
side effects from medication
findings from MRI or other investigations
previous treatments
general health
the potential benefits and risks of each treatment
individual treatment preferences

For some people, medication may control symptoms effectively for many years. For others, changes in their pain or how well they tolerate medication may mean it’s time to explore other treatment options.

A specialist assessment can help determine which treatments may be suitable and provide an opportunity to discuss their potential benefits, risks and expected outcomes.

Frequently asked questions

There is no single best treatment for everyone with trigeminal neuralgia. Medication is usually the first treatment, with carbamazepine or oxcarbazepine commonly used to control nerve pain.
If medication doesn’t adequately control pain or causes difficult side effects, procedures such as microvascular decompression, percutaneous treatments or stereotactic radiosurgery with Gamma Knife may be considered.
The most appropriate treatment depends on the type and cause of trigeminal neuralgia, general health, previous treatments and individual preferences.
The medication Carbamazepine is commonly recommended as a first-line treatment for trigeminal neuralgia. Oxcarbazepine is another commonly used option.
These medicines work by reducing the abnormal nerve signals responsible for trigeminal neuralgia pain. Treatment and dosage should be managed by a doctor, as these medicines can cause side effects and shouldn’t be stopped suddenly without medical advice.
If medication no longer provides adequate pain relief, or the dose required causes difficult side effects, a specialist may recommend reviewing the diagnosis and discussing other treatment options.
These can include different medications, microvascular decompression, percutaneous procedures or stereotactic radiosurgery such as Gamma Knife.
A referral for specialist assessment doesn’t necessarily mean a procedure will be recommended. It provides an opportunity to understand the available options, and which may be appropriate for individual circumstances.
Yes. Medication is usually the first treatment for trigeminal neuralgia and can provide effective symptom control for many people.
Gamma Knife radiosurgery is another option that doesn’t involve an incision or opening the skull. Although the name includes the word ‘surgery’, it uses focused radiation rather than conventional surgery.
Whether a non-surgical treatment is appropriate depends on individual circumstances and should be discussed with a specialist.
Gamma Knife radiosurgery is a form of stereotactic radiosurgery that uses highly focused beams of radiation to target a small area of the trigeminal nerve.
The treatment aims to disrupt the transmission of pain signals through the nerve. It doesn’t involve an incision or opening the skull and is generally delivered in a single treatment session.
Gamma Knife radiosurgery can provide meaningful pain relief for some people with trigeminal neuralgia, but results vary and pain can return over time.
Unlike some surgical procedures, pain relief is generally not immediate and may develop gradually over several weeks or months.
A specialist can explain the likelihood of pain relief and recurrence based on individual circumstances and the available clinical evidence.
Gamma Knife radiosurgery doesn’t usually provide immediate pain relief. Improvement may begin within several weeks, although for some people it can take several months.
Medication may need to continue while the treatment takes effect. Any reduction in medication should be discussed with the treating specialist.
Gamma Knife treatment does not involve an incision. A lightweight head frame or custom face mask is used to help keep your head in a precise position during imaging and treatment.
You may experience some temporary discomfort or tenderness associated with the head frame. Your treatment team will explain which approach will be used and what you can expect before, during and after treatment.
One of the main potential side effects of Gamma Knife radiosurgery for trigeminal neuralgia is a change in facial sensation. This can include numbness, tingling or altered sensation in part of the face.
Side effects and their likelihood vary between individuals. The treating specialist will discuss the potential risks and benefits before deciding whether treatment is appropriate.
Yes. Trigeminal neuralgia pain can return after a period of successful treatment. The likelihood and timing of recurrence varies depending on the treatment and individual circumstances.
If pain returns, further treatment with medication or another procedure may be possible.
There is currently no treatment that can guarantee trigeminal neuralgia will never return.
Microvascular decompression can provide long-lasting pain relief for many people with classic trigeminal neuralgia caused by compression of the nerve by a blood vessel.
Other treatments, including Gamma Knife radiosurgery and percutaneous procedures, can also provide significant pain relief, although symptoms may return over time.
The expected duration of pain relief and risk of recurrence should be discussed when considering treatment.
It may be appropriate to discuss further treatment options when trigeminal neuralgia pain is not adequately controlled with medication, medication is becoming less effective, side effects are difficult to tolerate, or symptoms are having a significant impact on everyday life.
A specialist assessment can help determine whether options such as microvascular decompression, a percutaneous procedure or Gamma Knife radiosurgery may be appropriate.
