Here are a couple of pics of my CT w/ contrast. I used 3D Slicer according to the tutorial written by Snappleofdiscord (thanks for that!).
This first one shows my right (red circles) and left (green circles) SPs. Using the ruler in 3D Slicer, I measured the right to be 4.5 cm (circle to circle) and the left to be 3.1 cm (4.4 cm if going out to the second green dot).
Oddly, my ENT measured my right and left to be 3.5 and 3.4, respectively. Did I measure too far towards the base or did the ENT just forget a centimeter?
This picture shows my right SP laying up against a vessel (not sure which one). By rotating the image, I can see that the vessel is touching the SP rather than in front of it.
Could this be why I have a swimmy/heavy-headed feeling in my brain that started a month or so before my ear pain? I would think that vessels on both sides would need to be impeded for anything like that, and the left SP doesn’t contact any vessels.
