Sphenopalatine ganglion (SPG) block
An innovative treatment is now available at Thompson that has been found to offer sustained relief to many of those who suffer from chronic migraines and cluster headaches.
An intranasal sphenopalatine ganglion (SPG) block is an image-guided procedure that is minimally invasive and involves no needles. It is performed by an interventional radiologist specializing in pain management.
During the procedure, a thin catheter is inserted through the nasal passages to administer lidocaine. The procedure takes approximately 20 minutes and involves minimal risks. Those include minor bleeding if the nasal passages are dry.
Patients who receive an SPG block often feel some relief within a few hours, with relief improving over the course of the next few days.
Essentially, the lidocaine acts as a “reset button” for the brain’s migraine circuitry, so when the initial numbing of the lidocaine wears off, the migraine trigger has less effect than it did previously. The procedure can also benefit patients with facial distribution pain syndromes such as trigeminal neuralgia and persistent pain over the upper and lower jaws after root canals.
No referral is needed for a minimally invasive SPG block, and Dr. Butani said most insurances cover the procedure.
