A New Sphenopalatine Ganglion Treatment



When a topical anesthetic (a lidocaine mixture) is administered to a special nerve center deep within the skull (the sphenopalatine ganglion), you may receive immediate migraine relief (if currently experiencing an acute migraine or headache) or it may decrease the severity of future migraines or prevent them (if administered prophylactically).


A medical expert in using x-ray imaging guidance (an interventional radiologist) places a small catheter the size of cooked spaghetti noodle into your nasal cavity and guides the catheter to the surface of the opening to the nerve center, the expert then transfers x-ray contrast material to safely ensure that the catheter is in the proper location. Then, the topical anesthetic is transmitted through the catheter into the opening to the nerve center, providing migraine relief.

Needle-Less Procedure

This procedure is to administer a topical anesthetic through the nose. No needles are used.

Possible Side Effects

Lidocaine is the most widely used topical anesthetic in the world. Side effects may include mild irritation, redness, swelling and numbness, these effects usually disappear within a few minutes or hours. A very serious allergic reaction to the drug is rare (blurred vision, mental/blood changes, drowsiness, dizziness, unusually slow heartbeat). Please discuss with our doctors these and other potential side effects.
