SPG Block ‐ A well‐tolerated, FDA approved technique to treat migraines, headaches and trigeminal neuralgia.
SPC Block — Headache Treatment
Nerves are cells that carry messages, including pain, as small electrical signals from one part of the body to another. Often, Nerves that are sensitized by trauma, infection or other causes can trigger pain. Numbing these nerves may interrupt the electrical signals and offer relief to the patient.
The sphenopalatine ganglion (SPG) is a bundle of nerves that is linked to other nerves within the head and typically involved in headaches and facial pain. The SPG is located just under the tissue that lines the back of the nose. When this bundle of nerves is anesthetized or
blocked it can help diminish or possibly even eliminate the pain; it may also help prevent this pain from reoccurring, especially cluster headaches, migraines, tension headaches and trigeminal neuralgia.
Temporary blocking the SPG can provide prompt, and possibly sustained relief from pain. An SPG block may be repeated as often as needed and is typically used in conjunction with patients previously prescribed medications. Patients can typically resume their normal activities after the procedure, including driving.
How is the procedure done?
A SPG block is performed within an out‐patient clinic setting and does not required sedation. The certified nurse anesthetist inserts a small soft catheter into each nostril and injects the numbing medication towards the back of the nose to the site of the SPG. The procedure is completed within seconds. Patients are then required to lie flat for 10 to 15 minutes and typically experience mild to no discomfort.
Temporary blocking of the SPG can provide prompt, and possibly sustained relief from pain. Talk to your medical provider and ask if they think this procedure could benefit you.
