None of those tests will tell if there is SM I'm afraid. Only an MRI can reveal syrinxes. The neurological exam could verify that there are neurological problems though that lean toward an SM diagnosis, if there's no PSOM.
It is standard for them to need to repeat the procedure at least once on many dogs -- just so you know this is very common. I hadn't heard that a CT scan for the absence of the plug improves the success rate -- but this may be the case or may be something they are trying to verify. I always understood the plug rcan reform for reasons not understood.
That is interesting that they include air scratching as I had understood from other folks that this usually is not seen with PSOM but Dr Cole is definitely the expert on this odd condition, so I will change what I have told people in the past.
I would def. go ahead with this study. OSU is def. doing SM work still as well but I don;t know what phase they are at and oif they are taking new cavaliers into thr study. I think the study went on hold when their neuros all went elsewhere over time and they only just got a new person in recently. The Cavalier Health Trust funds some of the OSU research but hasn;t been very clear in what is going on, who is participating, or what any of the results have been over the past few years. icon_nwunsure
Here's my email and the reply I received from Dr Cole this morning re; PSOM/SM correlation:

Hi Barb,
If we determine that Bentley does not have PSOM, or if he does have PSOM but
the clinical signs do not improve with the middle ear flush, then we would
consider SM as a cause of the clinical signs. When we do the CT scan, if
there are signs of SM, then the dog does have it....if there are NO signs
noted, that does not mean the dog does not have SM, and an MRI would need to
be done to determine if he had it or not. Right now, we do not have any SM
studies going on here at OSU.....
Hope this helps
Dr. Cole
I am definitely going to do the initial day of the study with Bentley. If he is eligible to continue to the second day then I will definitely do that, too.
Research is certainly tricky, isn't it?!? I can see the researchers must be very, very careful not to jump to any conclusions, and the results can be so foggy! My respect level is definitely rising for the doctors and researchers who struggle to maintain scientific method cleanliness!
