Migraine can be difficult to treat, particularly when headaches are frequent, severe, or do not respond well to standard medications. One treatment that may be considered for certain patients is a sphenopalatine ganglion (SPG) block. This minimally invasive procedure targets a cluster of nerve cells located deep behind the nose that plays an important role in headache and facial pain.
The sphenopalatine ganglion is a collection of nerve cells located behind the nasal passages. It is connected to the trigeminal nerve, one of the major nerves involved in migraine. It also contains autonomic nerve fibers that can contribute to symptoms such as tearing, nasal congestion, and facial pressure that sometimes accompany severe headaches.Because of these connections, temporarily reducing activity in the SPG may interrupt some of the pain signals involved in a migraine attack.
Despite the name โnerve block,โ an SPG block usually does not require an injection through the face or skull. For migraine treatment, a physician typically administers a local anesthetic, such as lidocaine, through the nostril. Depending on the technique, the medication may be delivered using a small catheter or applicator designed to reach the back of the nasal cavity, close to the SPG.
The procedure generally takes only a few minutes and is usually performed in the office. Patients remain awake, and sedation is typically unnecessary.
An SPG block may provide relatively rapid relief for some patients with an acute migraine. Studies have reported reductions in headache pain shortly after treatment, although results vary considerably from person to person.Some physicians also use a series of SPG blocks in patients with frequent or chronic migraine. However, the evidence for long-term migraine prevention is less established than it is for standard preventive treatments such as CGRP-targeting medications, certain oral medications, or Botox for chronic migraine.
For this reason, SPG blocks are generally considered one potential tool in a broader migraine treatment plan rather than a cure for migraine.
Patients may notice temporary numbness in the nose, throat, or roof of the mouth. A bitter taste, watery eyes, or mild nasal irritation can also occur. Occasionally, a small nosebleed develops. Because the treatment uses a local anesthetic and does not involve surgery, serious complications are uncommon.
An SPG block may be worth discussing if migraines are severe, prolonged, or difficult to control with usual rescue medications. It may also be considered when medication side effects or other medical circumstances limit treatment choices.
The most important point is that migraine treatment should be individualized. An SPG block will not work for everyone, but for selected patients it may offer a relatively quick, minimally invasive option for reducing migraine painโwithout adding another daily medication.
