Sphenopalatine Ganglion Block

A Sphenopalatine Ganglion Block (SPG block) is a procedure that delivers an anesthetic agent or numbing medicine to a collection of nerves for the purpose of stopping pain signals to the brain.
This is done by inserting a small plastic catheter (tube) with lidocaine, a local anesthetic. The medication baths the nerve endings behind this bony structures in the back of the nose and decreases the inflammatory response that results in pain signals reaching the brain. The procedure is not painful and takes about five minutes. There are few side effects associated with the procedure. Some patients experience tearing of the eyes, bitter taste in mouth, or mild dizziness.

This procedure may be done to stop an active migraine or as a series of 2 per week for 5 weeks to achieve long term relief.

If you have further questions about this procedure or other procedures in our office, call and speak to one of our caring providers.
