SphenoBlock is a minimally invasive procedure designed to temporarily block a collection of nerves (the sphenopalatine ganglion – SPG), effectively delivering pain relief. The SPG lies in a bony cavity which is deep in the midface nasal cavity and is related to a variety of facial pain conditions, such as migraines, cluster headaches and atypical facial pain.
A sphenopalatine ganglion block is done to:
- Diagnose the cause of pain in the face and head
- Manage the pain of certain types of chronic headaches
- Manage sympathetically maintained facial pain
During a SphenoBlock, pain-relieving medicine is injected to the region where the ganglion lies, sometimes with the use of a fine needle (the SphenoCath). This may reduce the release of the chemical norepinepherine activating the pain sensitive nerves and reduce the pain with long-lasting effects.
Patient will not feel numbness in the face.
Procedure is painless.
Requires no X-rays.
Takes about 30 minutes in the office.
Most insurance companies, as well as Medicare, cover the procedure.
SphenoBlock can often give immediate relief to an ongoing pain episode and/or help to give longer term relief by “resetting” this group of nerves (SPG).
If you’re currently taking medicine for migraines or other chronic facial pain, this simple procedure may over time replace the need for narcotics or other pain medications. It fits into the overall treatment plan with regards to medications, Botox injections and surgery for migraines.
