Sphenopalatine ganglion block for the treatment of acute headache: An old treatment revisited

The sphenopalatine ganglion (SPG) is a collection of parasympathetic nerve cells located just behind the bony structures of the nose. It is closely associated with the trigeminal nerve, which is the main nerve involved in headache disorders [1]. SPG nerve blocks for the treatment of headache were 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 [1]. If effective, an SPG nerve block would potentially be the ideal headache treatment – fast acting, while avoiding the need for intravenous access, and minimal adverse effects.
