Sphenopalatine Ganglion Blocks
Reducing migraine, facial, and head pain.
What are Sphenopalatine Ganglion Blocks? (SPGBs)
We inject an intranasal anesthetic to help manage acute migraines, acute and chronic cluster headaches, and a variety of facial neuralgias including trigeminal neuralgia and herpes zoster. The anesthetic blocks a collection of nerve cells that are closely associated with the trigeminal nerve, one of the main nerves involved in headache disorders.
What Conditions Do They Treat?
- Acute migraine headaches
- Acute and chronic cluster headaches
- Persistent daily headaches
- Facial neuralgia
- Trigeminal neuralgia
- Herpes Zoster
- Stress-related or sympathetic responses that worsen disorders like Fibromyalgia and TMJ
How long does the procedure take?
How fast is the relief?
Instant, and it lasts for many hours or even days. We typically recommend it as a series of treatments, which often provides lasting relief for up to several months.
SPGB has also been shown to reduce hypertension in some people with hyperactive sympathetic nervous systems and can eliminate hypertension in roughly one-third of newly diagnosed cases. This can make it an ideal treatment for patients with headaches or migraines who also suffer from high blood pressure due to an overactive sympathetic nervous system.
