SPG block for migraine

(sphenopalatine ganglion)

The sphenopalatine ganglion (SPG) is a bundle of nerve cells located behind the nose that is linked to the main nerve involved in headache, the trigeminal nerve. The SPG carries information about sensation, including pain, and by blocking the SPG with local anesthetics, pain can be reduced. The most common conditions treated by SPG blocks are cluster headaches and other trigeminal autonomic cephalalgias, trigeminal neuralgia and other facial pain syndromes, as well as migraine headaches.

How SPG BLOCKS Works AGAINST MIGRAINE

The Sphenopalatine Ganglion (SPG) is a group of nerve cells that is linked to the trigeminal nerve, the main nerve involved in headache.

The SPG, located behind the nose, carries information about sensation, including pain, and also plays a role in autonomic functions, such as tearing and nasal congestion.

The link between the SPG and the trigeminal nerve is important in head pain. If you apply local anesthetics (or numbing medications) to block or partially block the SPG, this can be helpful in reducing head and facial pain.

SPG blocks were first described in the 1900’s using a technique involving the application of numbing medication onto cotton swabs then placed into the back of the nose. This technique has been still used in emergency room to alleviate severe migraine/headache attack.

WHAT TO EXPECT

We use SphenoCath®, FDA approved device, to provide this procedure. The SphenoCath® Applicator is only available by prescription and should be administered by a qualified licensed health care provider.

A very thin cotton swab is inserted into nostrils to apply numbing gel to avoid discomfort. Then you will be asked to lie down on your back with your head extended. The catheter device will be gently placed into one nostril, and the catheter will be advanced. The numbing medication will be pushed through the syringe, and then the catheter will be taken out. The procedure will be repeated in the other nostril and in total takes between 10-20 seconds to complete. After the procedure is completed, you may be asked to lie down for about 15 minutes.

You may experience a brief or quick burning sensation or have a bad taste in your mouth as some of the numbing medication may be swallowed. Sucking on a piece of candy during the procedure can help.

Tearing and a brief temperature change may occur. You may experience an immediate reduction in head and/or facial pain, but results can take anywhere from 15 minutes to a few hours to occur.
