There is no direct link between the capillaries in the sinuses and the ear. The Eustachian tubes drain the middle ear (between the eardrum and the inner ear) into the nasopharynx, the part of the throat that is just behind the nose. The para-nasal sinuses drain into the nasal passages themselves at different points.

A number of things can go wrong with your eustachian tubes and middle ear, including: Blockage due to swelling. This swelling is most commonly caused by a sinus infection, a cold, or allergies.
What causes blocked Eustachian tubes?

People with sinus infections are more likely to develop plugged eustachian tubes. Altitude changes can also cause problems with your ears.
