50 million Americans experience and see a physician about headaches. Migraine headaches are a painful reality for approximately 28 million Americans, most of them women. Unfortunately, even a variety of medications do not provide adequate relief for many of these patients.

If you find that your current migraine treatment is not working, you may be considering newer alternative therapies. Horizon Vascular offers a short, simple procedure using an SPG (sphenopalatine ganglion) nerve block that may provide you with migraine pain relief.

What is the sphenopalatine ganglion (SPG)?

The sphenopalatine ganglion (SPG) is a group of nerve cells located behind the nose. The SPG carries information about sensation and pain to the brain where headache and migraine attacks may be generated. Targeting the SPG with neuromodulation, or alteration of nerve activity through delivery of electrical or pharmaceutical agents, helps disrupt the pain pathway.

What should you expect with a sphenopalatine ganglion block?

A sphenopalatine ganglion block involves delivering local anesthetics to the SPG through a small soft catheter that is gently placed into each nostril without the use of any needles or injections. The treatment takes only several minutes with minimal to no discomfort. Patients are able to return to work or other activities within 15 minutes.

Will an SPG block work for you?

This is a relatively quick and simple procedure that could improve your quality of life if you suffer from repeated headaches or migraines. Typically several treatments are performed over 1-2 months. Up to 70% of patients will find relief and improvement of their initial symptoms. In some cases, patients may have symptomatic relief in as little as 15 minutes. The SPG block has also been found to be effective in treating patients with trigeminal neuralgia and atypical facial pain.
