SPG blocks work best on headaches that have parasympathetic-related symptoms associated with them. SPG blocks can also treat temporomandibular joint disorders, trigeminal neuralgia, and post-herpetic neuralgia.

Jack Bragan MDDoes anyone routinely do this procedure ? and if so, is it difficult to get these patients to agree to this procedure ? and how good are your results ?
Thanks

Veronica B MDI’m a part of an online ED physicians group. I personally have not tried this, but other physicians are reporting good success. Sounds like they haven’t had problems getting patients to agree.

Adelaide Viguri, DOWe do routinely offer this block as part of our treatment for migraine and orofacial pain. I would say about a quarter of patients agree to the procedure, largely because it sounds more uncomfortable than it actually is. Patients that I performed the procedure on did not report any discomfort. I tried it on myself – the sensation of a cotton tip applicator in the tour nasal cavity does feels odd but otherwise, very tolerable. In my experience, I’ve had good results for migraines with autonomic symptoms and trigeminal neuralgia, but not successful for TMJ pain.

Barbie LongHi Doctor.
Do you know if these are effective for left sided moving into the facial and global?

Diana TowleMy daughter just had an SPG block with a doctor who uses the Sphenocath. She has been suffering from a constant 24/7 migraine for a year. The block eliminated her facial pain and pressure temporarily. It came back and made her realize how much facial pain and pressure she actually has which is good information to know as we are consulting with an ENT – though the pain in her temples is worse. She is having it done again as it seems the effects can be cumulative in chronic migraine patients. The hope is that it will calm and reset the nerve. It is one of the least invasive things a migraine patient can try.

Denise KI have had multiple SPG blocks and each has given me tremendous relief when oral medications (triptans, opioids, muscle relaxants,) and various IV medications in the ER failed. I have suffered from both migraines and TMJ disorder (bilaterally) for nearly 25 years. Sometimes the headaches are a mix of both, sometimes clearly one or the other. I did not hesitate when the SPG block was offered. The Q-tip type applicator was only tried once and it couldn’t be advanced far enough. So all of my blocks have been via a syringe with a really long needle or the SphenoCath device. No difference in either, just excellent and much-needed complete relief. Any discomfort is minimal and resolves quickly, or I wouldn’t have repeated this so many times.

Lisa KernDenise,
Have you been to an ENT to look at you septum? If it deviates to the side of the nose and touches, it could cause a migraine. A 20 minute in office surgery can fix it and it does have a strong correlation to migraines.

Barbie LongDo they let you have a supply of these at home?

Jan M.I have had the SPG procedure several times (I also have occipital nerve blocks in the back of my head same day). SPGs have been a great relief to what was debilitating pain behind and above my eyes after a brain injury. It is similar to a small catheter inserted momentarily in your nostril to pour the “magic medicine” down. It is within minutes, sometimes immediate, you feel relief. Very worth any initial awkwardness of having something put in your nose. Its quick and easy and provides great results!

Kimberly, RN, BSNWe started using the SphenoCath to deliver the anesthetic. it allows delivery to the ganglion. I ran an informal study prior to bringing this to my patients… we were realistically 90%. Decreased frequency and duration of cluster headaches, migraines… and a case of trigeminal neuralgia. Dolor Technologies distributes the catheter.

DebKimberly –
Where are you located?
Do you know of any doctors in Orlando doing this procedure?
Tks.

DeanaHi Kimberly, How long do the results typically last for the majority of your patients? My daughter suffered a concussion/whiplash 9 months ago and has had a constant migraine 24/7. She tried the SPG block and had relief but if only lasted 4 hrs and the headache came back much worse. She would try it again but is afraid of a similar result. Just wondering your experience/opinion with this procedure.

Naomi, PA-CIn my office-based practice, I have offered SPG blocks via syringe and angiocath (needle removed) for the past year. I use 0.4 cc of 2% Lidocaine per nostril. A piece of hard candy prior to the instillation of the Lidocaine blunts the bad taste, and the swallowing decreases any numbness.
Some patients have immediate relief, some take 20 minutes, some take close to an hour; but they all (so far) have gotten 3-8 VAS points of relief.
Most patients go on to have reduced number and severity of migraines. The usual schedule of treatment is one block per week for three weeks. After that, the patient returns when their symptoms first begin to resurface –usually 6- 8 weeks later. Repeating the block then typically results in 2-4 months of reduced migraines.
I also administer the block for anxiety and TMJ pain with good results.
I do not pre-numb the nostril nor use a heart monitor. Approximately 10% of patients (usually of Celtic heritage) will feel light-headed upon completion of the block. An additional 3 minutes or so of sitting is usually sufficient to restore them.
SPG blocks are easy and efficacious. Try them !

LucyIs the schedule 1 time per week for 3-4 weeks in row normally that general practice for administrating the spg block via SpinoCath?
January 18, 2020
Naomi, PA-CIt is a reasonable schedule. I prefer to perform 3 blocks within 10-14 days. Results seem to last longer with clustered treatments than with them spaced a month or so apart.

Dr Ira L ShapiraI have been utilizing Sphenopalatine Ganglion Blocks (SPG Blocks) since 1986. I( teach patients to self-administer the blocks with cotton-tipped catheters that give continual capillary release of lidocaine. Self-Administration give the patient control of their pain relief and allows more frequent use.
The blocks can be used prophylactically to prevent migraines or at the first sign of onset. They decrease suffering and reduce needs for visits to ER for relief.
2% lidocaine is used which has natural anti-inflamatory properties.
