Sphenopalatine Ganglion (SPG) Block
SPG block is an accepted, minimally invasive therapy for chronic headaches. This is a “needle-less” intranasal approach to the Sphenopalatine ganglion, which is located in the back of the nasal cavity. This ganglion is located outside of the brain and as a result, is the only ganglion exposed to the environment. It also has very close connections with many nerves, including the trigeminal nerve. Many studies have demonstrated that the SPG is directly involved in the pathway of numerous forms of headaches and, when stimulated, can worsen symptoms and cause debilitating chronic headaches. By disrupting the function of the nerves in the SPG, it is possible to reduce facial pain and headaches, leading to significant improvement in symptoms and quality of life.
The diagram illustrates how this procedure is performed. After administering an anesthetic spray into each nostril, the patient is asked to lie down with his/her neck slightly extended. A fluoroscope is then used to guide a small catheter into each nostril. A small amount of contrast is injected to confirm adequate positioning of the catheter. This is then followed by the administration of lidocaine to block the SPG. The procedure takes 15-30 minutes. No sedation is required.
As with all the procedures at Cosmetic and Vascular Suite NYC, all SPG blocks are performed by Dr. James Silberzweig in a relaxed and professional atmosphere.
