SPG Injections
Migraine Treatment

What is the SPG Block?
The sphenopalatine ganglion (SPG) is a cluster of nerve cells that may contribute to head and face pain. The cluster is located under the tissue lining the back of the nose. By applying a local anesthetic to the nerve bundle, nerve impulses may be blocked. This is otherwise known as an SPG Block.

How long before I notice migraine improvements?
Oftentimes individuals will experience immediate relief of a current headache or migraine. Over the course of the 4 treatments, frequency and intensity of migraines should be diminished. The first 2 treatments are scheduled 2 weeks apart, with the final 2 treatments 4 weeks apart.


Are there any side effects to the procedure?
Normally, there are no serious side effects associated with the SphenoCath® treatment. Common reactions may include eye watering and a feeling of tightness in the face during the treatment which resolve soon after.

How is the SphenoCath the most accurate SPG block?
Because the device extends the reach of its soft applicator tip over the middle turbinate and rests directly above the sphenopalatine ganglion, SphenoCath® is able to drip medication directly onto the sphenopalatine ganglion. This highly-targeted positioning means that medication reaches the area directly rather than in a periphery spray-type application as with other SPG blocks.
