Abstract
The sphenopalatine ganglion (SPG) is a large extracranial neural structure that is located in the pterygopalatine fossa (PPF). It has rich autonomic sympathetic and parasympathetic components, which explains the autonomic features associated with cluster headache. Cluster headache involves activation of the parasympathetic outflow from the superior salivary nucleus of the facial nerve, predominantly through the SPG.
