The Sphenopalatine Ganglion (SPG) Block is a type of injection that targets pain in the head and face by numbing the nerves of the Sphenopalatine Ganglion. This treatment is often used to relieve pain from chronic migraines as well as some severe non-migraine headaches. In today’s post, we’ll discuss how the SPG block for migraines is used to relieve pain for those who suffer from chronic headaches and how it differs from other treatments.
What is the Sphenopalatine Ganglion?
The Sphenopalatine Ganglion, or SPG, is a group of nerves gathered behind the nose, deep inside the face. These nerves carry pain signals to the brain from the eyes, face, and sinuses. Facial pain associated with a migraine headache is usually attributed to the SPG nerves.
How does the SPG Block for Migraines work?
The SPG is connected to the brain via the trigeminal nerve, a nerve usually associated with headaches. The SPG block for migraines works by injecting a numbing medication into this nerve, effectively blocking the pain signals transmitted to the SPG nerves.
What is the procedure like?
There are multiple ways to administer an SPG block. The best method will depend on the patient’s situation. According to the American Migraine Foundation, the use of an SPG block for migraines was first described in the 1900’s using a technique involving the application of numbing medication onto cotton swabs then placed into the back of the nose.
The easiest way of receiving an SPG block for migraines is through the nasal cavity. This process involves the insertion of a thin tube through the nose to deliver the numbing medication to the site of the SPG nerve bundle. This is the most common method of conducting this procedure. Another technique used to block the SPG involves using a needle to inject the SPG through an area on the cheek. This process is invasive, and usually requires the use of an x-ray machine to place the injection correctly.
What makes the SPG Block different from other treatments for migraines?
The best treatment for chronic migraine headaches will vary from patient to patient.
The SPG block for migraines offers immediate relief for patients that can last anywhere from several weeks to a few months. Some patients find that multiple injections help them achieve better, more long-lasting relief. Unlike Botox injections, SPG blocks can be used to treat both episodic and chronic migraines. SPG blocks also provide relief faster than Botox, and have fewer associated side effects.
