This site is dedicated to exploring the amazing uses of the Sphenopalatine Ganglion Block (SPG Block), the block utilized by Dr Milton Reder in the book “Miracles on Park Avenue”

The Sphenopalatine Ganglion is also known as the Pterygopalatine Ganglion, the Nasal Ganglion, Sluder’s Ganglion and Meckel’s Ganglion.

Blocks can be done with nasal catheters (Sphenocath, Allevio and Tx360) or by injection either intraorally or extra-orally.

I firmly believe that the best method for chronic pain is self-administered blocks with cotton tipped nasal catheters.  This allows the patient to control their pain without constant trips to ER departments or physicians offices.

There is an amazing number of disorders that can  be trearted utilizing these blocks including all types of headaches and migraines, cluster headaches and other autonomic cephalgias.

SPG blocks can also be used to treat anxiety, depression, eye pain multiple conditions of the ear, trigeminal neuralgia, complex regional pain syndromes and even prevent and treat essential hypertension.

Please brouse thru the site to learn more.

There are also various types of neurostimulation that can be done with the sphenopalatine ganglion.  Many of these are invasive and carry surgical risks.

The Myomonitor, an ULF-TENS  has been used by neuromuscular dentists for over 50 years to treat chronic head, neck and TMJ disorders and one of its actions is to stimulate the spenopalatine ganglion.  This stimulation may explainwhy neuromuscular dentistry is amazingly successful at treating both TMJ disoders and headaches.
