The SPG Block or Sphenopalatine Ganglion Block is truly one of the most miraculous treatments for pain. It often works where other treatments have failed. The Sphenopalatine Ganglion is also known as the PterygoPalatine Ganglion, Meckel’s Ganglion and the Nasal Ganglion.
It is an old procedure originally described in 1908 by Sluder. Sluder’s Neuralgia is considered one of the early descriptions of Cluster headaches and TMJ Syndrome headaches.The Sphenopalatine Ganglion is the largest parasympathetic ganglion of the head. It also has sympathetic nerve fibers and somatic nerve fibers. It affects are primarily thru the autonomic nervous system and it acts similat to propanolol to shut off “Fight or Flight” reflex which causes anxiety and chronic pain.
Patient Testimonials are often amazing with SPG Blocks, the following is a patient who had migraines for more than 10 years. this video is after her first appointment and an SPG Block.
