Hi, and welcome!
I agree that your styloids aren’t super long, but they are extremely thick as you’ve spotted! The internal jugular vein , the vagus nerve and the internal carotid artery are all close together and emerge from the jugular foramen, a small hole in the base of the skull which is right next to the styloid process…so it’s easy to see if a styloid process is very thick or angled it could easily compress these blood vessels where they emerge from the skull.
I’m not very good at recognising the individual blood vessels in the axial images you’ve posted, but if you’re interested, one of our members posted a tutorial about this:

The styloids look pretty thick on these images too, to me the IJV looks slightly flattened indicating compression between the styloid process and the C1 process…
Your neck does also look quite straight to me, which means it’s lost it’s natural curve, which is quite common but can worsen symptoms. There’s some info about this and some neck exercises which you can do to restore the curve which sometimes helps:

Have you got a follow up appointment arranged with Dr Oliviera to discuss the CT? I hope that he reviews the images himself, and doesn’t just rely on the report- lots of members have had reports from radiologists saying nothing remarkable is seen, when the have elongated styloids & vascular compression… your symptoms certainly indicate vascular compression, as well as the more common ‘classic’ ES symptoms!
