Located in the pterygopalatine fossa, it is the largest parasympathetic ganglion in the head. This ganglion has three roots (sensory, parasympathetic, and sympathetic) with branches reaching to the maxillary nerve, nervus intermedius, and the trigeminal ganglion. The SPG is responsible for innervating specific sites of the head and neck. This includes the lachrymal glands, the paranasal sinuses, and the gingiva.
SPG blocks have been performed to treat chronic headaches for around 100 years. Past methods include using needles through the maxilla or the soft palate of the roof of the mouth.With these methods to administer medication directly to the SPG because of its small location. With the Allevio™ SPG catheter, it allows medical professionals to pinpoint the exact location the medication needs to be delivered. It has been found to reduce pain level, duration, and frequency of even the most severe headache sufferers.
