@RitaPita - Nice job on the 3D conversion! I annotated 3 of your images. I’m a little confused though as the images you have marked as left look like the right side & the right look like the left. Are the images posted in “mirror image” positions (i.e. the first image looks like the left to me but you labeled it as the right)? I’ve annotated them according to the way you labeled them (L & R) above.
In this first one, your left styloid looks minimally elongated but it is very pointed & you have a couple of small areas of calcification on your stylohyoid ligament. It appears the small vein branching off your IJV may be causing some compression to your internal carotid artery (ICA) as the area of the artery below the branch looks engorged to me, whereas the area above it is much narrower. Your IJV doesn’t look compressed in the styloid/C1 area, but lower down within the white oval, there appears to be compression which could come from the SCM or other muscle/soft tissue. Other head positions could possibly cause IJV compression as has been speculated. You have some stylohyoid ligament calcification on each of the lesser horns of your hyoid. You’ve lost the natural curve in your cervical spine which can bring the styloids closer to nerves & blood vessels. The curve can be restored using gentle PT exercises, but it takes time & determination. List of my favourite resources on YouTube to learn anatomy
Second picture annotations are self explanatory
In this image, the base of your right styloid looks quite thick & the styloid is also very pointed but overall it’s not very elongated. You have at least one section of calcified stylohyoid ligament as well as s-h ligament calcification at the hyoid’s lesser horn. Your IJV may be somewhat narrowed lower down as on the left, but I can’t tell for sure.
Since I’m not a doctor, these are things you can discuss with whichever ES specialists you consult with to get their opinions.
