SPG Block Q & A

What is SPG?

The sphenopalatine ganglion (SPG) is a group of nerves that relate to the trigeminal nerve. It’s this nerve that is responsible for carrying pain signals to the brain. The SPG also assists with certain bodily functions, including nasal congestion and eye tearing.

The relationship between SPG and headaches makes it possible to reduce the severity and frequency of headaches by numbing this main nerve.

How does an SPG block work?

An SPG block is a specialized technique that delivers anesthetic medications through a catheter your provider inserts through your nose to access the nerve.

Your provider may use the guidance of an X-ray to ensure the medication is reaching the nerves. Using the imaging device provides a closeup view of your internal structures for treatment accuracy.

What can I expect during the SPG block procedure?

Your provider performs the block procedure in a comfortable office environment. To keep you comfortable, they may provide a numbing medication for your nose before inserting the catheter.

Once the catheter is in the proper position, your provider pushes through the anesthetic medication until it reaches your SPG, then immediately removes the catheter. They use the same technique in your other nostril.

What are the side effects of an SPG block?

You can expect to go home right after your treatment. It’s normal to feel some temporary numbness in your throat that should resolve in a few hours. You may need to limit what you eat to prevent choking.

For some, an SPG block procedure can also trigger a nosebleed. If you have excessive pain or signs of an infection, notify The Center for Neurology and Neurophysiology as soon as possible.

How long does an SPG block last?

Your provider can discuss how long you can expect to experience a relief of symptoms during your consultation, based on your medical history and the severity of your pain.

Typically, an SPG block for treating chronic migraine pain may involve a series of treatments over several months. However, each person responds differently to treatment and the team at The Center for Neurology and Neurophysiology can determine how many treatments you need to achieve your desired results.
