The sphenopalatine ganglion (SPG) is a bundle of nerves located in the back of the nose that control face and head pain. We can block the nerve impulses by applying a local anesthetic to the bundle of nerves causing a reduction in pain. This is known as a sphenopalatine ganglion block. The Sphenocath is a specially designed catheter that allows us to deliver anesthetic directly to the SPG without the use of needles or harsh medicine. Some conditions relieved by the SPG block are headache pain, craniofacial pain, migraines, and trigeminal neuralgia.
