Artery of Trigeminal Nerve Ganglion

The artery to trigeminal nerve ganglion has been identified as a branch that arises from the extracranial segment of middle meningeal artery prior to entry into the foramen spinosum. The role of the artery in being the arterial supply to trigeminal nerve ganglion is supported by electrophysiological and clinical suppression of trigeminal nerve activity during selective intra-arterial injection of anesthetics.
