This minimally invasive procedure offers immediate relief for most patients with chronic and episodic migraine, cluster headache, chronic daily headache and for other facial pain and headache syndromes. The SphenoCath® device is a soft, flexible catheter that delivers pain-relieving medication 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 SphenoCath® is designed to quickly and comfortably deliver medication to the area of the sphenopalatine ganglion.
Benefits of SphenoCath:
- 2 to 5 minute in-office procedure
- Majority of patients experience immediate relief
- Very high success rate
- Safe for adults and children
- Very low risk and side effects/li>
The duration of pain relief is different for every patient. Oftentimes this treatment can help patients’ bodies naturally combat the triggers of their pain (e.g., allergies, hormones, etc.) by “resetting” their sphenopalatine ganglion. Some patients require only one treatment. Other patients experience relief after the first treatment for one or two weeks, then require additional treatments. For these patients, the length of time between treatments typically increases to four weeks, and eventually longer.
During the Procedure
Patients lie flat. The small catheter is inserted into the patient’s nose, and pain medication (Lidocaine) is delivered through it. The procedure is not painful when performed correctly, although some patients experience a minor discomfort when the small, soft SphenoCath® is inserted into the nose.
SPG block using the SphenoCath® takes 2-3 minutes.
After the Procedure
Patients should remain in a flat or reclined position for 10-15 minutes afterward to maximize the benefit of the procedure.
Patients can resume their normal daily activities immediately.
