Sphenopalatine Ganglion Block in League City: A Targeted Nerve Block for Migraine and Facial Pain
A minimally invasive, nonopioid option for stubborn head and facial pain, led by Dr. Ho, a board-certified anesthesiologist. Nearby Houston locations welcome League City patients, open 5 am to 9 pm daily.
When Migraines and Facial Pain Keep Coming Back
You’ve felt this before. A migraine that wipes out an entire afternoon. A cluster headache that hits on schedule and buckles your knees. Facial nerve pain that flares from a gust of wind or a sip of cold water. Across League City, it’s just as common. According to the American Migraine Foundation, nearly one in six Americans lives with migraine, and standard medication doesn’t always bring lasting relief.
Sphenopalatine Ganglion Block, sometimes shortened to SPG block, targets a nerve cluster sitting deep behind the nose that plays a major part in head and facial discomfort. It’s an option some patients explore once standard migraine and facial pain care hasn’t gone far enough. At Catalyst Health & Wellness, Dr. Ho performs the procedure in the office, with medical screening beforehand and monitoring afterward. Used for head and face pain, it’s an off-label option, meant to work alongside the care you already receive from your neurologist or headache specialist, not replace it. Responses differ from patient to patient.
What Exactly Is an SPG Block?
The sphenopalatine ganglion is a compact cluster of nerve cells resting deep behind your nose, inside a space known as the pterygopalatine fossa. It ranks as the largest bundle of nerve cells in the head outside the brain, and it sits at a busy junction of sensory and autonomic pathways connected to head and facial pain.
An SPG block delivers a local anesthetic to that ganglion to quiet the signals traveling through it. The most common technique is transnasal, a method ScienceDirect’s clinical overview describes as well established. Dr. Ho guides a slim, soft catheter through the nostril and places the anesthetic at the back of the nasal cavity, right where the ganglion sits. There’s no facial needle with this technique, and the whole procedure takes only a handful of minutes.
Doctors have targeted this ganglion for head and facial pain for well over a hundred years, dating back to Dr. Sluder’s first description of it in 1908. It’s a well-established anesthetic nerve block. Used for headache and facial pain, it’s considered an off-label option, meaning it isn’t FDA-approved for these specific uses. Dr. Ho will walk you through what that means for your case during your consultation.
What the research points to:
What Our Patients Say
How the Sphenopalatine Ganglion Block Functions
Think of the sphenopalatine ganglion as a control switch for much of the feeling and autonomic activity in your face, sinuses, and the front of your head. In many headache and facial pain conditions, that switch stays overactive, driving both the pain and the stuffy, watery-eyed, congested feeling that so often comes along with a bad flare.
Quieting an Overactive Nerve Center
By bathing the ganglion in local anesthetic, an SPG block temporarily interrupts the signals passing through it. For some people, quieting that hub may help settle a pain pattern that's become self-perpetuating. Because the anesthetic sits right at the ganglion, its effect stays focused on the pathways tied to head and facial pain rather than spreading through the whole body.
Interrupting the Pain and Reflex Loop
The sphenopalatine ganglion carries parasympathetic fibers, which explains why so many headaches arrive with a runny nose, watery eye, or facial pressure on the affected side. Interrupting that loop may calm both parts at once for some patients. Everyone responds differently, and the block is meant to support your existing care and make the rest of your treatment plan easier to build on.
Head and Facial Pain Conditions We Evaluate for SPG Block
We evaluate sphenopalatine ganglion block for League City patients whose head or facial pain hasn’t responded well to first-line care. Whether it suits you depends on your diagnosis, history, and goals.

Cluster Headache
The condition with the strongest research support for SPG block.
Trigeminal Neuralgia and Facial Nerve Pain
Sharp, shocking facial pain that's hard to control.
Persistent Facial Pain
Ongoing facial pain without a clear structural cause.
Post-Traumatic Headache
Headache lingering after a head injury, an area still being studied.
Other Head and Face Pain

Your Sphenopalatine Ganglion Block Path With Catalyst Health & Wellness
We've designed every step to feel simple, clear, and centered on your needs. Here's what to expect.
Step 1: Free Phone Consultation
Your journey starts with a no cost, confidential phone call. It isn’t a sales pitch, just a real conversation about whether an SPG block makes sense for you. You’ll:
- Ask any questions about the procedure
- Share your headache or facial pain history and current symptoms
- Learn what a transnasal SPG block involves
- Get honest guidance on whether it fits your situation
There’s no charge and no obligation to continue.
Step 2: Medical Evaluation
If you decide to move forward, you’ll complete a medical evaluation so we can confirm the block is appropriate for you. This includes:
- Review of your diagnosis, medical history, and current medications
- A look at which headache or facial pain treatments you’ve already tried
- Any imaging or records your referring physician has shared
- A clear explanation of what to expect during and after the procedure
Step 3: Day of Procedure
Preparation is simple:
- No special fasting for most patients
- Wear comfortable clothing
- Arrange transportation if we advise it for your situation
- Plan for an easy rest of your day
Step 4: The Sphenopalatine Ganglion Block Procedure
The block itself takes just a few minutes, and you stay awake and alert the whole time.
- You recline comfortably while Dr. Ho positions a slim, soft catheter in the nostril
- He delivers the local anesthetic to the back of the nasal cavity, at the ganglion
- Most people find any discomfort mild
- You may notice a bitter taste, mild numbness at the back of the throat, or a little nasal drip
Those sensations are expected and pass on their own.
Step 5: Recovery and Observation
After the block, you’ll rest while we monitor you.
- We observe you for a short period afterward
- You take it easy for the remainder of the day
- Most people return to normal activity soon after
Step 6: Assessing Response and Follow-Up
Responses to SPG block vary widely from person to person. Some notice a change within the same day, others need a short series of visits.
- We’ll track how you respond
- Repeat blocks may be recommended based on your results
- Together we’ll decide whether and when to continue
Since everyone’s different, we personalize follow up around your individual response.
The Research Behind Sphenopalatine Ganglion Block
Interest in the sphenopalatine ganglion for head and facial pain stretches back more than a hundred years, and the techniques keep evolving. A narrative review published in Brain Sciences looked at SPG block, neuroablation, and neurostimulation across a range of head and facial pain conditions. It found the firmest support for cluster headache, alongside encouraging evidence in migraine and trigeminal neuralgia, and noted that larger controlled trials are still needed to confirm these findings.
A clinical overview published in Current Pain and Headache Reports describes SPG neuroablation as a focused, minimally invasive option for selected cluster headache cases, and stresses that careful patient selection and follow-up monitoring shape how well it works.
Notable findings include:
- The longest history and strongest backing sit with cluster headache
- Encouraging evidence appears in migraine and trigeminal neuralgia
- The procedure stays minimally invasive, nonopioid, and repeatable
- Larger controlled trials are still needed across most applications
- Patient selection and clinical monitoring shape the outcome
That’s a fair picture of where the evidence stands: long used, promising, and still under study. Part of what your consultation covers is Dr. Ho’s read on that research and whether it applies to your particular pain.

Commonly Asked Questions
Get Help NowDoes a sphenopalatine ganglion block hurt?
Most people find it easy to tolerate. Because the common approach goes through the nostril instead of a needle into the face, any discomfort is usually mild. You might feel the catheter and notice a bitter taste as the anesthetic settles in.
How is an SPG block different from a stellate ganglion block?
They target different nerves for different problems. Stellate ganglion block goes to a bundle of nerves in the neck and is used for trauma and anxiety symptoms. Sphenopalatine ganglion block sits behind the nose and is used for head and face pain. Dr. Ho performs both.
How long does relief last?
It varies quite a bit from person to person, and some people need more than one visit. There’s no set timeline we can promise. We’ll track how you respond and plan any follow up around your results.
How many treatments will I need?
That depends on your condition and how you respond. Some people are managed with occasional single blocks, while others do better with a short series. Dr. Ho will recommend an approach based on your results.
Is the sphenopalatine ganglion block FDA approved for headaches?
The block is an established anesthetic procedure. Used for headache and facial pain, it’s an off label option and isn’t FDA approved for those specific conditions. We’ll always be straight with you about that.
Can I drive myself home?
For many patients the transnasal block doesn’t require sedation, but we’ll tell you at your evaluation whether to arrange a ride based on your specific plan. When in doubt, bring someone along.
Can an SPG block be combined with my current headache treatment?
Yes. It’s meant to work alongside the care you already have, not replace it. We’re glad to coordinate with your neurologist or headache specialist so everyone’s on the same page.
Will insurance cover a sphenopalatine ganglion block?
Coverage varies by plan and diagnosis. We can help check your benefits and go over payment options during your consultation.
