Sierra Corbin, a physician assistant at Gulf Coast Breathe Free, said that sinusitis can increase mucus production, leading to drainage that allows bacteria to travel up the Eustachian tube and potentially cause ear infections. This statement was made on Instagram on November 27, 2024.
“Anytime that you have sinusitis, inflammation of the sinuses, you also may produce a lot of extra mucus,” said Corbin, according to Instagram. “That mucus can go down the back of your throat, and that is basically where your ear connects. If you have a lot of drainage going down the back of your throat, that bacteria can actually travel up that middle ear tube, the eustachian tube, and get into the ear and cause ear infections. Or even just simply the inflammation of the eustachian tube can lead to problems like pressure or difficulty in equalizing pressure, and that leads to infections as well.”
According to the Mayo Clinic, sinusitis, or inflammation of the sinuses, can lead to increased mucus production. This excess mucus can drain down the back of the throat, reaching the opening of the Eustachian tube, which connects the middle ear to the nasopharynx. If bacteria-laden mucus enters the Eustachian tube, it can travel to the middle ear, potentially causing an ear infection.
As detailed in a Wikipedia article on Eustachian tube dysfunction, this tube plays a crucial role in equalizing pressure between the middle ear and the external environment. Inflammation or blockage of this tube, often due to sinusitis or upper respiratory infections, can impair its function. This dysfunction can lead to symptoms such as ear fullness, discomfort, and difficulty in pressure equalization, increasing the risk of developing ear infections.
The New York Post reports that blowing your nose too forcefully can push mucus into the Eustachian tubes, increasing the risk of ear infections. To minimize this risk, experts recommend blowing one nostril at a time and doing so gently. This practice helps prevent pressure buildup that can force bacteria-laden mucus into the middle ear.
