Hearing and Sinuses
The sinuses are air-filled channels located in your bones near your cheeks, forehead, nose and ears. Normally, mucus produced by the sinuses drains into your nose. The sinuses can become inflamed or swollen, causing them to become blocked. When this happens, a small channel leading from your ear to your throat may swell as well – the Eustachian tube. If the Eustachian tube swells, it blocks the passage from the middle ear to the throat, putting pressure on the eardrum. Symptoms may include a “plugged feeling”, popping or clicking, pain, or hearing loss.
