Can a Sinus Infection Lead to an Ear Infection?
There’s a reason ear, nose, and throat doctors are called just that. Your ears, nose, and throat are all part of the otolaryngeal, or upper respiratory, system, connected by canals and mucus-producing tissues. Inflammation in one area can easily lead to inflammation in another.
At SLENT, with locations in Mandeville, Slidell, and Hammond, Louisiana, our otolaryngology specialists can diagnose and treat allergies, sinusitis, and ear infections, and clarify if there’s a link between sinus issues and your ear infection.
Sinus infections
Sinus infections, also known as sinusitis, can have either a bacterial or a viral cause. The common cold is the most likely culprit, but airborne bacteria, allergens, and even fungi can also be responsible.
In most cases, sinusitis presents as pain and pressure in your face, nasal congestion, and/or a thick, mucous nasal drip or discharge. If the infection is viral, we treat the symptoms and wait it out. If the cause is bacterial, we can use antibiotics to fight the infection.
Ear infections
The most common type of ear infection is acute otitis media, which is inflammation of the middle ear behind the eardrum. If the eustachian tubes that allow drainage are swollen or otherwise blocked, fluid collects and causes swelling and intense pain.
Ear infections can definitely happen because of an upper respiratory infection like sinusitis or rhinitis. Bacteria get into the eustachian tubes, causing infection, inflammation, and blockage. Left untreated, ear infections can result in temporary or permanent loss of hearing.
The connection
It’s estimated that 37% of acute otitis media cases are preceded by acute bacterial sinusitis. Even if the initial cause of a sinus infection is viral, like the common cold, mouth breathing can allow more bacteria into the otolaryngeal passageways.
Repeated bouts of sinusitis followed by an ear infection should be taken seriously. Repeated ear infections can damage your hearing.
Treatment for acute otitis media
Fortunately, bacterial ear infections caused by sinus infections are readily treated with antibiotics. Make sure you finish the entire round of medication even if you’re feeling better after a few days, and go back to your doctor for a follow-up to check your ears.
Also, treat your sinusitis with appropriate decongestants, and wash your hands and face regularly. If you’re around a lot of people, you might consider wearing a mask to prevent exposure to more viruses and bacteria.
If you seem to be constantly struggling with sinus infections and ear infections, it’s safe to bet the two are related. To learn more, schedule an evaluation at SLENT by calling the location closest to you, or visit the contact page for more information.
