Choose SphenoCath® for Migraine Pain Relief

The SphenoCath® device is a one-of-a-kind patented, soft, flexible, spaghetti-sized catheter which employs a flexible outer sheath with soft edges for comfort and an inner angled flexible catheter to deliver medication without the use of a needle inside the nasal passageway with maximum patient comfort. SPG block stands for sphenopalatine ganglion block. The sphenopalatine ganglion is a collection of nerve cells located just under the tissue lining the back of the nose. By applying a local anesthetic to the area, nerve impulses can be temporarily blocked, providing relief from various types of pain. The patented SphenoCath® is designed to quickly and comfortably deliver medication to the area of the sphenopalatine ganglion. 


  • Very low risk 2 to 5 minute in-office procedure
  • Majority of patients experience immediate relief 
  • Very high success rates
  • Reimbursed by most insurance companies

About the Procedure

Coastal Spine and Pain Center’s board-certified pain specialist Eugene Wang is trained in this advanced technique and it is offered as part of our comprehensive care for our patients.

We are a Certified Center of Excellence for SphenoCath®. In addition to migraines, SphenoCath® can be used to treat a number of other headache conditions, such as facial pain and cluster headaches.

Will it hurt? Some patients experience a minor discomfort when the small, soft SphenoCath® is inserted into the nose, but the procedure is not painful when performed correctly. In the past, SPG block was accomplished with a long needle through the side of the head or with a stiff, cotton-tipped applicator through the nose. The patented SphenoCath® uses no needles and is designed to be comfortable and safe for patients.

What medications are used? Most practitioners perform SPG block using a local anesthetic such as lidocaine, the same or similar medication that is injected by a dentist or used to anesthetize a laceration before stitches. With the SphenoCath®, however, no needles are used. The medication is absorbed through the lining of the nose.

What are the risks? The risks of using the SphenoCath® include irritation to nasal cavity or mucosa, nose bleeding and/or mild pain.
