What is a Sphenopalatine Ganglion Block?
The Sphenopalatine Ganglion (SPG) is a group of nerve cells linked to the main nerve involved in headaches, the trigeminal nerve. The SPG is located behind the nose and carries the pain sensation.
A sphenopalatine ganglion block is a minimally invasive migraine treatment used to treat headaches and facial pain by the use of an injection. This procedure has been used by pain management physicians for many years to treat migraine pain.
A sphenopalatine ganglion block can be performed in several approaches including the transnasal, transoral and lateral approach. The transnasal approach is the most common and typically takes 15-30 minutes to complete. This migraine treatment can be performed as a diagnostic block to test the pain response or as a therapeutic block to administer the injection of a local anesthetic and a neurolytic agent to alleviate the pain.
What are the Benefits and Risks of a Sphenopalatine Ganglion Block?
A sphenopalatine ganglion block is a safe and effective migraine treatment with a low risk rate. The pain relief is felt almost immediately but may take a few days to reach full benefit. The most common side effects are developing a bitter taste in the mouth or numbness in the back of the throat from the local anesthetic dripping down into the mouth and throat.
