I recently saw a physician who came in to learn how to do nasal catheter treatment blocks of the Sphenopalatine Ganglion. He had a history of decompression surgery followed by 18 months of very severe pain and never achieved complete relief.
I brought him in and administered an SPG Block with lidocaine and it relieved his trigeminal Neuralgia Symptoms. I talked to him later and he had repeated the block and again achieved pain relief.
The first description of the SPG Block was in 1908 for Sluders Neuralgia. Today it is assumed his patient was either cluster headaches, TMJ disorder or Trigeminal Neuralgia.
I decided a search of Spenopalatine Ganglion Blocks for treating Trigeminal neuralgia would be worthwhile and found 10 abstracts on PubMed.
The newest study was from the polish neurological scociety and was limited to patients who had failed pharmocologic interventions. The Blocks were done by the Supra-Zygomatic Approach that I teach for injections. The Full PubMed abstract is below.
The second article was published in Pain Physician. 2013 Nov-Dec;16(6):E769-78.
“A novel revision to the classical transnasal topical sphenopalatine ganglion block for the treatment of headache and facial pain.” It describes the use of the TX360 device for SPG Blocks. There is an ongoing study that will finish in 2017.
There are three devices that are all similar that deposit anesthetic over the area of the sphenopalatine ganglion via a nasal catheter and the patients stays supine for 30 minutes. All three have similar effects. I sometimes use a sphenocath device but I prefer the “old -Fashioned” cotton tipped nasal catheters. They work very similar to the devices but provide a continual feed of anesthetic via capillary action, do not require lying supine and most important patients can learn how to self administer the block with the nasal catheter. I do one patient who self administers with the Sphenocath device as well.
Another PubMed abstract (below) also from Pain Pract. 2012 Jun;12(5):399-412.
The pterygopalatine ganglion and its role in various pain syndromes: from anatomy to clinical practice.
discusses utilization of SPG Blocks for multiple pain conditions and found that “various pain syndromes including headaches, trigeminal and sphenopalatine neuralgia, atypical facial pain, muscle pain, vasomotor rhinitis, eye disorders, and herpes infection. Clinical trials have shown that these pain disorders can be managed effectively with sphenopalatine ganglion blockade (SPGB).”
There is another study from Pain Pract. 2010 Jul-Aug;10(4):370-4. looking at
“Pulsed radiofrequency V2 treatment and intranasal sphenopalatine ganglion block: a combination therapy for atypical trigeminal neuralgia” While it discusses radiofrequency lesions in addition to SPG Blocks and Methadone. I would always prefer to sty less invasive which is why I find self administered blocks to be so successful, the patients uses them as needed..
Still another article discusses the use of a 8% lidocaine spray (abstract below) Br J Anaesth. 2006 Oct;97(4):559-63. Epub 2006 Aug 1.
Intranasal lidocaine 8% spray for second-division trigeminal neuralgia. The reults were less impressive but the lidocaoine is not directed ove the area of the sphenopalatine ganglion. I would always rather use directed catheters or injection over a nasal spray. A nasal spray can make catheter insertion more comfortable.

Trigeminal Neuralgia: First Line Approach with SPG Blocks Can Be Safe and Effective
The sphenopalatine ganglion (SPG) block is a safe, easy method for the control of acute or chronic pain in any pain management office. It takes only a few moments to implement, and the patient can be safely taught to effectively perform this pain control procedure at home with good expectations and results. Indications for the SPG blocks include pain of musculoskeletal origin, vascular origin and neurogenic origin. It has been used effectively in the management of temporomandibular joint (TMJ) pain, cluster headaches, tic douloureux, dysmenorrhea, trigeminal neuralgia, bronchospasm and chronic hiccup.

The effectiveness of neurolytic block of sphenopalatine ganglion using zygomatic approach for the management of trigeminal neuropathy.
Malec-Milewska M1, Horosz B2, Kosson D2, Sekowska A2, Kucia H2.
This study was performed to present the outcomes of trigeminal neuropathy management with the application of neurolytic block of sphenopalatine ganglion. This type of procedure is used in cases where pain is not well controlled with medical treatment. Twenty patients were treated with sphenopalatine ganglion neurolysis after their response to pharmacological management was not satisfactory. Significant pain relief was experienced by all but one patient and they were able to reduce or stop their pain medication. The time of pain relief was between a few months and 9 years during the study period. Number of procedures implemented varied as some of the patients have been under the care of our Pain Clinic for as long as 18 years, satisfied with this type of management and willing to have the procedure repeated if necessary. It appears that neurolytic block of sphenopalatine ganglion is effective enough and may be an option worth further consideration in battling the pain associated with trigeminal neuropathy.

A novel revision to the classical transnasal topical sphenopalatine ganglion block for the treatment of headache and facial pain.
Candido KD1, Massey ST, Sauer R, Darabad RR, Knezevic NN.
The sphenopalatine ganglion (SPG) is located with some degree of variability near the tail or posterior aspect of the middle nasal turbinate. The SPG has been implicated as a strategic target in the treatment of various headache and facial pain conditions, some of which are featured in this manuscript. Interventions for blocking the SPG range from minimally to highly invasive procedures often associated with great cost and unfavorable risk profiles.
The purpose of this pilot study was to present a novel, FDA-cleared medication delivery device, the Tx360® nasal applicator, incorporating a transnasal needleless topical approach for SPG blocks. This study features the technical aspects of this new device and presents some limited clinical experience observed in a small series of head and face pain cases.
Pain management center, part of teaching-community hospital, major metropolitan city, United States.
After Institutional Review Board (IRB) approval, the technical aspects of this technique were examined on 3 patients presenting with various head and face pain conditions including trigeminal neuralgia (TN), chronic migraine headache (CM), and post-herpetic neuralgia (PHN). The subsequent response to treatment and quality of life was quantified using the following tools: the 11-point Numeric Rating Scale (NRS), Modified Brief Pain Inventory – short form (MBPI-sf), Patient Global Impression of Change (PGIC), and patient satisfaction surveys. The Tx360® nasal applicator was used to deliver 0.5 mL of ropivacaine 0.5% and 2 mg of dexamethasone for SPG block. Post-procedural assessments were repeated at 15 and 30 minutes, and on days one, 7, 14, and 21 with a final assessment at 28 days post-treatment. All patients were followed for one year. Individual patients received up to 10 SPG blocks, as clinically indicated, after the initial 28 days.
Three women, ages 43, 18, and 15, presented with a variety of headache and face pain disorders including TN, CM, and PHN. All patients reported significant pain relief within the first 15 minutes post-treatment. A high degree of pain relief was sustained throughout the 28 day follow-up period for 2 of the 3 study participants. All 3 patients reported a high degree of satisfaction with this procedure. One patient developed minimal bleeding from the nose immediately post-treatment which resolved spontaneously in less than 5 minutes. Longer term follow-up (up to one year) demonstrated that additional SPG blocks over time provided a higher degree and longer lasting pain relief.
Controlled double blind studies with a higher number of patients are needed to prove efficacy of this minimally invasive technique for SPG block.
SPG block with the Tx360® is a rapid, safe, easy, and reliable technique to accurately deliver topical transnasal analgesics to the area of mucosa associated with the SPG. This intervention can be delivered in as little as 10 seconds with the novice provider developing proficiency very quickly. Further investigation is certainly warranted related to technique efficacy, especially studies comparing efficacy of Tx360 and standard cotton swab techniques.

The postsynaptic fibers of the pterygopalatine or sphenopalatine ganglion (PPG or SPG) supply the lacrimal and nasal glands. The PPG appears to play an important role in various pain syndromes including headaches, trigeminal and sphenopalatine neuralgia, atypical facial pain, muscle pain, vasomotor rhinitis, eye disorders, and herpes infection. Clinical trials have shown that these pain disorders can be managed effectively with sphenopalatine ganglion blockade (SPGB). In addition, regional anesthesia of the distribution area of the SPG sensory fibers for nasal and dental surgery can be provided by SPGB via a transnasal, transoral, or lateral infratemporal approach. To arouse the interest of the modern-day clinicians in the use of the SPGB, the advantages, disadvantages, and modifications of the available methods for blockade are discussed.▪

Intranasal lidocaine 8% spray for second-division trigeminal neuralgia.
Kanai A1, Suzuki A, Kobayashi M, Hoka S.
Trigeminal nerve block has been widely used for trigeminal neuralgia. This may induce paraesthesia. The second division of the trigeminal nerve passes through the sphenopalatine ganglion, which is located posterior to the middle turbinate and is covered by a mucous membrane. We examined the effectiveness of intranasal lidocaine 8% spray on paroxysmal pain in second-division trigeminal neuralgia.
Twenty-five patients with second-division trigeminal neuralgia were randomized to receive two sprays (0.2 ml) of either lidocaine 8% or saline placebo in the affected nostril using a metered-dose spray. After a 7 day period, patients were crossed over to receive the alternative treatment. The paroxysmal pain triggered by touching or moving face was assessed with a 10 cm visual analogue scale (VAS) before and 15 min after treatment. Patients used a descriptive scale to grade pain outcome, and were asked to note whether the pain returned and how long after therapy it recurred.
Intranasal lidocaine 8% spray significantly decreased VAS [baseline: 8.0 (2.0) cm, 15 min postspray: 1.5 (1.9) cm, mean (SD)], whereas the placebo spray did not [7.9 (2.0) cm, 7.6 (2.0) cm]. Moreover, pain was described as moderate or better by 23 patients of the lidocaine spray and 1 of the placebo group. The effect of treatment persisted for 4.3 h (range 0.5-24 h).
Intranasal lidocaine 8% administered by a metered-dose spray produced prompt but temporary analgesia without serious adverse reactions in patients with second-division trigeminal neuralgia.

Sphenopalatine ganglion block for treatment of sinus arrest in postherpetic neuralgia.
Saberski L1, Ahmad M, Wiske P.
A 64-year-old woman presented with bradycardia from sinus pauses during exacerbations of postherpetic trigeminal distribution neuralgia. She had underlying systemic lupus erythematosus. Sphenopalatine ganglion blockade was employed to treat her pain. The episodes of bradycardia resolved with successful alleviation of pain. This report emphasizes that a sphenopalatine ganglion blockade can be employed in the treatment and prevention of sinus arrest associated with postherpetic trigeminal distribution neuralgia.
Hi, I do believe this is a great web site.

I think I need to check out your site more reguraley.
Trying to decide which is the best option: SEPT block or Gasterrian block
I would always start with SPG Block as first step due to safety and afficay.
I have suffered with constant TN pain on the right side of my face for 4 years now.. The pain was intense for two years. I used the typical drugs to relieve symptoms, with muscle relaxers. Just recently I had a SPGB using the cotton swab procedure. I walked out of the office with just a small dull discomfort. Nowhere near the pain I was in before. Picking up nasal sorry today. Too me it felt as thou the nerve was in a tangled knot. When the lidocaine was administered the nerve untangle itself. I could feel it across the entire area of where I hurt on my face. Especially the nerve area across my cheek that affect pain over a upper tooth to my ear pain. I am Happy as a Lark! Crying with Joy and relief!
This is very exciting! Did the doctor teach you how to self administer SPG Blocks? Self-Administration give you control of your pain issue and elimates trips to the doctor and reduces medical expenses.
I am very happy for you.

Curious, I had the block done via the nasal passages with a syringe. I had a series of them and did not get any lasting relief. I only had days. Is the 30 minute procedure better? Should I look into it?
I am a firm believer in patients learing how to self administer SPG Blocks. They usually have an additive effect but I prefer patients do the blocks twice a day for 1-2 weeks until pain is greatly reduced or eliminated. Less frequent use is needed over time. If you had relief for days from a single block imagine what might occur with twice daily self administration.
SPG Blocks are only one tool. I typically utilize neuromuscular diagnostic orthotics and other techniques to reduce and/or eliminate pain.

Have you tried self administration of SPG Blocks yet?
I got the spg nerve block yesterday for trigeminal neuralgia and chronic daily migraine. Not impressed at all!! Was really hoping that it would work for those conditions, plus I have fibromyalgia and anxiety. I hoped the spg block would work on the sympathetic nervous system and reset it to para-sympathetic. But I’m in bed today with all of the regular chronic symptoms.
I tried to talk the doctor into doing another spg block ASAP. Like another within the same week. Or to give me some lidocaine to self administer at home 2xday. She said come back in 6 weeks. Let’s see how well it works by then. I was shocked! I could tell right then it wasn’t a home run for me. And when I got home nothing had set in as a change for the positive.
Needless to say that I am extremely disappointed! I waited for a few months to get an appointment. Being that I am chronic for years with all of the conditions that I mentioned I was hoping my doctor would be a little more aggressive in treating me. Doctors aren’t suffering like we are. So they can’t relate to months of waiting -while in terrible pain.
I am hoping that I can get a doctor to allow me to administer the 2xday lidocaine.
I think if that doesn’t help then I’m doomed. But I am holding out hope that the lidocaine 2xday will be the trick. I am bed ridden daily for years with trigeminal neuralgia and migraine.
I don’t know why I bother to hold out hope for something that will reset this pain. But I want to be a success story. And I want to be able to show other complex complicated chronic pain people that a treatment might be our path to finding life again.
I can’t afford to go to Chicago to the doctor that does the teaching of self administration of the lidocaine. And I’m too sickly to make the trip.
Thanks for your website! I appreciate everything you have on here and that you let us blog.
I don’t want to sound depressing that the one time administering of the spg block didn’t work for me in any way like it did so fantastically for others. But in case someone else didn’t get great results the first time, or anything to speak of food results. I would say keep trying because the theory behind the spg block makes a lot of sense. And I have read online that many many other people didn’t get results the first time either.
The doctor used the Allevio device to administer the lidocaine 4%. After the administration of the lidocaine I got a bad headache worse than what I had going into the office. She said that often happens. I think that if I can get a spg block regularly by q tips saturated with lidocaine or the Allevio or one of the other fancy squirt guns. I rather try that than the needle going through the roof of the mouth or through my jaw joint! There are far too many side effects and damage.
I asked my doctor if she would give me the steroid. She said that steroids applied to the spenopalatine ganglion causes atrophy!!! And that you don’t want to atrphoy that ganglion as that can cause a lot of problems of its own. She said that is one nerve group that you don’t want to mess with! I was glad that she was up front with me about that and I wanted to pass that along! I saw many videos of doctors adding steroids to the lidocaine trying to get better results. But I am finding out that the steroids in the spg nerve block is not a good idea and can be detrimental.
I am sorry to hear the first SPG Block didn’t work. In my office I routinely teach self administration exactly because of patients like you. It is possible to do the injections which are surprisingly easy and I often use them to “Jump Start” treatment. I hope you do better with additional blocks in the future. If you contact ICCMO.org they may be able to put you in contact with a doctor who learned Self-Administration of the blocks at one of my lectures.
What do you think about using cocaine instead of lidocaine for the blocks? I went to a pain doctor that uses cocaine but haven’t read of anyone using it. I might have to have the procedure done but am nervous about the cocaine.
I originally utilized cocaine for SPG Blocks in 1986. I might still use it but the Drug Enforcement Agency (DEA) keeps careful watch on pharmaceutical grade cocaine and there is a lot of paperwork involved to account for all cocaine including “left-over) after the block.
I teach self-administration which would not be possible with cocaine. I will assure you it is an excellent method. I will utilize injections on the most severe cases which I find extremely efficatious followed by self-administration.
The pain doctor said she can use cocaine or lidocaine but finds the cocaine relief lasts longer. I am confused by the time it takes to work. Everyone says they got relief right away but the doctor said it takes 2 weeks. Does that sound right?
Where did you have the
Block taken care of? I have suffered 4 years and I’m breaking my mouth is so bad. My front teeth and r side tissues. Help me please
I teach patients to self-administer SPG Blocks trans-nasally with cotton tipped nasal catheters in Chicago.
