Sphenopalatine Ganglion Block

Sphenopalatine Ganglion (SPG) Blocks

The sphenopalatine ganglion (SPG), located deep in your face, controls many involuntary functions, such as nasal congestion. It also carries sensory information and, as such, is thought to be a key nerve in understanding headaches, migraines, and atypical facial pain. If you suffer from such pains, your doctor may perform a sphenopalatine ganglion block to treat your pain.

Unlike most nerve and ganglion blocks, the procedure is not an actual injection. When receiving an SPG block, your doctor will anesthetize your nasal passage, then slowly lead a cotton-tipped applicator through the nasal passage to the ganglion. An anesthetic solution is then placed through the applicator, allowing the numbing solution to bathe the ganglion. More solution may be applied every 5-10 minutes with the total procedure lasting approximately 30-40 minutes. After a brief observation period, you can then go home the same day. You may feel numbness in your face afterwards. This procedure should improve the intensity and frequency of your pain and can be repeated if necessary.

The SPG block is performed in a variety of ways and is a safe, proven procedure, with risks including bleeding, infection, or reaction to the anesthetic. Let your doctor know if you are on blood thinners, are immunosuppressed, or have an active infection.
