Nerve blocks are a fast and often effective way to relieve pain caused by trigeminal neuralgia. Although they do not work for everyone, many patients experience significant improvement.
What Is a Nerve Block?
A local anesthetic, often combined with a corticosteroid, is injected near the affected nerve.
The anesthetic interrupts pain transmission, while the steroid reduces inflammation and may prolong the effect.
The procedure is usually performed under ultrasound guidance.
Which Nerves Can Be Blocked?
Depending on the location of pain, blocks may target:
- Ophthalmic branch (V1)
- Maxillary branch (V2)
- Mandibular branch (V3)
In classical trigeminal neuralgia, blocks closer to the trigeminal nerve root may also be performed.
When Are Nerve Blocks Considered?
They may be recommended when:
- pain is severe and medication is ineffective,
- medication cannot be used,
- rapid pain relief is needed,
- other facial pain conditions are present.
Benefits
Many patients experience immediate relief. The effect may last from days to months, oral medication requirements often decrease, and normal daily activities can usually be resumed.
Safety
Nerve blocks are minimally invasive and generally safe. Minor bruising or temporary numbness may occur. Serious complications are rare when performed by an experienced physician.
If relief is short-lived, other options such as cryoablation, radiofrequency thermocoagulation, or neurosurgical procedures including Gamma Knife or CyberKnife may be considered.
