Am I a Candidate for a Sphenopalatine Ganglion Block?

If you suffer from headaches, craniofacial pain, facial pain, migraines or trigeminal neuralgia. These are all common ailments that can be treated by a SPG through a new technique offered by our Interventional Radiologists team using the SphenoCathTM.

What is SphenoCathTM ?

The SphenoCathTM is a small soft tube specifically designed to be gently inserted into a patient’s nose, as they lie on their back, and deliver medication precisely and consistently to the area of the sphenopalatine ganglion. It is a directed, no-needle therapy for migraine headaches and trigeminal neuralgia.

How does a Sphenopalatine Ganglion Block Work?

A ganglion is a collection of nerve cells that helps to regulate certain functions within your body. The sphenopalatine ganglion or SPG is located in the back of the nose and it plays a role in many different types of headaches. The medication used is intended to temporarily block the function of the SPG. This is a relatively quick and simple procedure that will improve your quality of life if you suffer from repeated headaches or facial pain.

How is a Sphenopalatine Ganglion Block Accomplished?

A flexible SphenoCathTM catheter is placed into the nasal passages under fluoroscopic guidance and then a medication is delivered to the mucosa over the sphenopalatine ganglion effectively delivering an SPG block for migraine pain without the use of needles, cotton swabs or harsh medicines. Patients, in most instances, can resume their normal activities within 15- 20 minutes.

What Should I Expect?

In most cases the provider will pre-medicate with a topical anesthetic spray or gel directly into the nose. Some patients will experience an unpleasant taste in their mouth or a temporary unpleasant numbness in their throat after the procedure. Some will feel difficulty in swallowing however this will resolve itself in a few minutes. Generally there is very little discomfort with the procedure.
