Styloid bone is a normal bone present, it's enlargement can cause pain in the neck region. The ct images aren't clear so can't comment about it

Blockage may be due to eustichian tube obstruction

It doesn't look Eagle syndrome. CT scan looks normal.

Hi, I am Dr. Atul Kumar Nimawat MS ENT. Your symptoms are more suggestive of chronic rhinosinusitis with nasal polyposis, possibly causing Eustachian tube dysfunction—hence the ear blockage and referred throat symptoms. The persistent DNS on CT can occur post-surgery due to residual or deviated bony-cartilaginous structures. Regarding the Styloid Process: Elongated styloid (Eagle’s syndrome) is rare. Typically causes throat pain, foreign body sensation, or pain on swallowing/turning head, not mucus or ear block alone. It is a benign anatomical variant, rarely symptomatic unless very elongated and medialized.
