The Sphenopalatine Ganglion (SPG) is a group of nerve cells located behind the nose that is linked to the main nerve involved in headache. These nerve cells carry information about sensation, including pain.
This procedure is done in an outpatient setting. Your physician will apply a local numbing medication. After your nose has been allowed to numb, you will be asked to lie down on your back with your head extended. A small plastic tube connected to a syringe called a Sphenocath will then be placed into one nostril and numbing medication will be inserted around the SPG. The procedure will be repeated in the other nostril. After the procedure has been completed, you may be asked to lie down for a short period of time and your blood pressure may be checked. Sphenocath can be repeated as often as needed to reduce pain.
