This is Dr. David
I am wondering how your dentist found something in your sinuses? did he feel your sinuses? how does your dentist look into your sinuses?
if you have a mass in your sinuses, you need to see an ENT ear nose throat doctor and get a CT scan of your sinuses to look inside
xrays of your teeth is not enough to look into your sinuses
yes, a mass in your sinuses can cause hearing issues and hearing symptoms and ear pain.
you need to have the area better imaged with a CT or MRI scan
you will need to get a biopsy of the mass as soon as possible
and to see an ENT doctor as soon as possible
let me know if you have other questions.
