Hi Nikki,
A good neurologist or ENT really should be able to tell you whether you have GPN or not. There's a pretty clear process of elimination. One of the simpler ones are having a bit of freezing in the area of the glossa and if it relieves the pain it's a pretty clear indicator of GPN, as long as Eagles Syndrome has been ruled out. Also, just giving a detailed description of your experience to a neurologist would likely lead to a pretty conclusive diagnosis on the spot. Unfortunately GPN doesn't show up on MRI's.
Myself I just recently (Nov. 19/2010) had a resection of my Glossopharyngeal nerve with Dr. Christopher Honey at Vancouver General Hospital. At this point I feel like the procedure was a 100% success without any residual nerve damage. The procedure is done the same as an MVD up to a point. In both procedures, they drill a hole the size of a 50cent piece. I always pictured like a drill from a hardware store but they actually use like a dental drill and they go round and round, making the outline of a circle until they have just about broken through and they pop the bone cork out. There's lots of You Tube videos where you can see it being done. Our neck muscles run up under our skull and actually block the view of the brain at that point so they have to part the muscle (you definitely feel that after the surgery for a few weeks, but not unbearable) to gain access to the brain. The Glossopharyngeal nerve is a little buried in brain tissue so they carefullyl have to work away to expose the nerve. As they do that, it also exposes the artery that is usually the culprit of most of your suffering because it lays on the nerve and over stimulates it. This is where the procedures differ. With the MVD they would at this point place teflon batting between the nerve and the artery as a buffer. This usually produces relief for most people. The downside is that over time the padding can move and the pain can recurr. Another issue is that there is a bit higher occurence of meningitis. Meningitis while very serious is quite treatable, unfortunately for many people who have had a MVD and develop meningitis, the meningitis can be chronic. Meaning that even after being treated, the meningitis will continue to recurr and cannot be "cured" until surgery is done again to remove the teflon batting.
The "resection" I had done, requires the surgeon to expose the nerve down to the roots. They then, one at a time, stimulate the each root to see if it produces facial or any muscle movement. If it does then they leave it alone. If it doesn't, then it is a pain receptor and so they section off that root. After it's done there is nothing left behind.
Statistics seem to suggest that both procedures carry the same risks for facial paralysis or swallowing issues. I was Dr. Honey's 8th such procedure for GPN and all 8 have been successful without residual damage. He's also done about 200 similiar procedures for Trigeminal Neuralgia with complete success and no residual damage. He seems quite adamant in his belief that MVD is an outdated procedure.
I'm not a doctor and I barely know my ass from a hole in the ground, so I can't tell you if he's right or not. I can just say that he inspired total confidence in me and I have not seen much information out there about this procedure so I just thought I'd spread the word.
I have to say he had a Neuro Surgeon from Britain working with him as a fellowship. I took this to mean that they had not yet completed their training/residency but when I asked her about this she said "no, I'm a full fledged neuro surgeon but doing a fellowship with an experienced surgeon is just an option to add to your skills and working with someone like Dr. Honey is a real feather in your cap. I could tell she really admired him.
Anyway, hope that info helps.

Oh Tess, you are beautiful! I'm trying to figure this site out. I had a larangotomy (where's the spell-check on this thing?) - you know what I mean - YESTERDAY! I am NOT 10000000% convinced that I have GPN....so I had my ENT look WAY down there. He removed a node (what does that mean? I was DOPEY when we discussed it) but he said it was not at all suspicious and prob not the cause of pain. Sure hurts like hell today! Anyway, SO glad to know you're here. And so very happy you're improving daily. I'm still considering the MVD at the House Ear Clinic in LA.......but I need to be a gagillion % SURE that I do have GPN before I have that surgery. Don't know what it will take before I'm convinced.......Take good care, gorgeous!! Nikki
