The Sphenopalatine Ganglion (also known as Nasal Ganglion, Pterygopalatine Ganglion, Sluder’s Ganglion and Meckel’s Gangliion) is the largest Parasympathetic Ganglion of the head. While it is a Parasympathetic Ganglion it also carries Sympathetic Fibers from the Superior Sympathetic Cervical Chain and Somato-Sensory Nerves of the Trigeminal Nerve and the Facial Nerve.
It was originally described in 1908 by Dr Greenfeld Sluder fort he treatment of Sluder’s Neuralgia, also called Pterygopalatine Gangliion Neuralgia and Sphenopalatine Ganglion Neuralgia. It is now thought that he was actually describing a Trigeminal Autonomic Cephalgia (TAC), most likely Cluster Headache or a Tempormandibular Dysfunction. Costen diid not describe TMJ disorders until 1934.
The Trigeminal Nerve is often called the Dentist’s Nerve and it is the primary cause or source of all headaches, migraines, TACs regardless of the specific diagnosis.
the Myomonitor was originally invented by Dr Bernard Jankelson who was looking to help his wife’s treatment of MS, Multiple Sclerosis. It is the basis for all of Neuromuscular Dentistry and has an incredible safety record that is over 50 years. Neuromuscular Dentistry is incredibly successful in elimination of a wide variety of headaches, TACS and migraines when utilized in conjunction with a Diagnostic Neuromuscular Orthotic. The uniqueness of the Myomonitor is it’s use of ULF-TENS to relax muscles utilizing a single synapse reflex and an Anti-Dromic pulse.
The Myomonitor effectively serve as a Sphenopalatine Ganglion Neuromodulation Device that does not require surgical implantation. The Parasympathetic and Sympathetic fibers travel with the branches of the Trigeminal and Facial Nerves.
The Myomonitor works with three electrodes, two are placed over the coronoid notch to allow access to the maxillary division of the Trigeminal Nervous System which gives access to the entire Trigeminal Nervous System. The third electrode is the input to the other two electrodes and is placed on the neck. The current also passes thru the occipital nerve, both the greater and lesser occipital nerves and possibly the vagus nerve as well.
These are all areas that use Neuromodulation for treating Headaches, Migraines, TACs and TMD /MPD disorders.
Neuromodulation works similarly to Sphenopalatine Ganglion Blocks as a reset of the nervous system similar to rebooting your computer when it is not working correctly. Self-Administered SPG Blocks is probably the most effective approach among available modalities.
