Hi Tim,
It worked! Very good job with the pictures!
Maybe just the sensitivity “shift” (in volume rendering) could be optimized a bit. For orientation I used the hyiod and thyroid cartilage for the adjustment of structures shown or hidden. Just play a little bit around with these functions if you like.
Looks like a type of Eagle Syndrome in my opinion: your styloids are normal length but a bit thick at the base. I think what causes your problems are partly calcified stylohyoid ligaments on both sides. (Or do you just show the right SP from the one and the other side? It is a little bit hard to see for me.) They are a little bit below the styloids looking like small toothpicks. That one on the left looks very close to the carotid artery but that is hard to estimate with this few images. I would definitely consult a specialist for Eagle Syndrome e.g. Dr. Samji.
Furthermore on the left a litte bit close to the jaw I see two little dots. Don’t know exactly what that is but it looks a bit too far from the stylohyoid system. Maybe from stylomandibular ligament? Or stones in the salivary glands? But I think your severe symptoms are most likely from the calcified stylohyoid ligament(s).
Sorry for the only semi-good news, man! Hopefully you can see a Specialist soon, wish you that!
Best regards

Certainly looks like calcified ligament, I agree…the styloids look very small as TheDude says, but wide. Not sure about the dots, whether they’re something or an artifact?

Agree with the above (not a doctor here). At least from what I see, I think the IJVs shouldn’t be affected directly by the styloid processes, so that’s something probably to cross out of the list.
But the shape of the neck is suspiciously “military-neck”-like (What is military neck or cervical kyphosis?). And call that a co-incidence, most CT scans that I have seen of people with Eagle’s have this “feature” (including mine). Maybe that is what makes the difference between people with asymptomatic and symptomatic elongated styloid processes, and similarly people with straight necks can have similar symptoms… Who knows.

Interesting theory!
Again, good observation, vdm. You’ve pointed this out on other members’ images. I keep forgetting to pay attention to that.
Our necks are supposed to have a slight kyphotic curve (like the curve in the lumbar spine/lower back). When that is absent/lost from too much looking down, injury or other cause then neck, shoulder, arm & upper back problems can ensue.
