Sphenopalatine Ganglion Block

What is Sphenopalatine Ganglion Block?

The Sphenopalatine Ganglion is a group of nerve cells closely related to the trigeminal nerve. An SPG Block is an intervention that uses an anesthetic to block these nerve cells. This treatment can be remarkably effective in reducing pain signals in the face and head.

What Can It Treat?

The SPG Block is primarily utilized for the following conditions:

Chronic headaches and migraines

Cluster headaches

Certain types of facial pain

How Is It Administered?

The procedure is typically performed in an outpatient setting. Here’s how it’s done:

Preparation: The patient is positioned comfortably, and the area is cleansed.

Anesthetic Application: A small amount of local anesthetic is applied to numb the area.

Injection: A thin, flexible Qtip is guided to the sphenopalatine ganglion. The anesthetic is then left for several minutes to absorb into the ganglion and to block the nerves.

Monitoring: The patient is observed for a brief period to ensure that the procedure was successful.

What Are the Risks?

Though an SPG Block is generally considered safe, like all medical procedures, it carries some risks:

Discomfort or irritation at the injection site

Allergic reaction to the anesthetic



Incomplete pain relief

However, these risks are low

Sphenopalatine Ganglion Block is a potent tool in the arsenal of pain management. It offers a targeted approach to relieving chronic and acute facial and head pain, with minimal risks and side effects.
