Hearing loss is never an easy thing to deal with – but what should you do if it’s only affecting one ear? Keep reading to learn everything you need to know about hearing loss in one ear, what causes it, and the treatments available to get your hearing back to normal.

Why Does It Only Affect One Ear?

Hearing loss is a funny thing. While most people associate it with the elderly or people who suffer some sort of eardrum trauma, it could actually happen at any point and for a number of reasons. Hearing loss that only affects one ear can happen all of a sudden or gradually and could happen in one ear or the other.

Sudden sensorineural hearing loss (SSNHL), if that’s what it is, usually remains unexplained and affects about one out of every 5,000 adults per year, though many cases go unreported or even misdiagnosed. Many people first experience SSNHL by waking up one morning and realizing they can only hear out of one ear. While it might be tempting to write this sudden loss of hearing off as temporary, it’s actually very important that you go see a hearing specialist right away – otherwise, a non-serious bout of hearing loss can turn into something much more damaging and permanent.

What Causes Hearing Loss in One Ear

The most common reasons for a sudden bout of hearing loss in one ear are believed to be blockages, damage, medication side effects, or a viral inner ear infection, which is the most common cause. However, it’s important to note that the cause for sudden hearing loss is unknown in about 90% of all the cases that are diagnosed.

Viral inner ear infections often cause the hearing nerve to swell in the inner ear canal. Unchecked inflammation can cause the nerve to eventually die. That’s why it’s so important to get your ear checked out in the case of SSNHL, since letting it sit and fester may cause permanent damage. Immediate care can help reduce the swelling.

Fortunately, the other causes for SSNHL are much less serious and easy to treat. Blockages are often caused by compacted earwax, which is pushed down into the ear canal by Q-tips. A hearing specialist can clear out a bad case of clogged ears, though there are several over-the-counter remedies available for more mild cases, such as ear drops that can unclog your ears.

How to Treat Single-Ear Hearing Loss

There are several treatments available for temporary hearing loss that affects one ear. In many cases, rest is the best bet to get your ears back to normal, especially if you experience hearing loss after a night out at a loud concert. Even in cases like that one, where it’s obvious that the hearing loss is caused by loud noises, it’s still important to see a hearing specialist to ensure that there aren’t any underlying issues that could make you more susceptible to hearing loss in the future.

As mentioned above, you can see a hearing specialist to unclog your ears or use over-the-counter treatments. Ear infections, on the other hand, may either clear up by themselves (under a doctor’s supervision) or may need to be treated with antibiotics, depending on if the infection is viral or bacterial.

Some medications are considered to be ototoxic, which means that they cause hearing loss under certain circumstances. These medications include aspirin, some antibiotics, chemotherapy, and diuretics, to name just a few. If you are concerned about hearing loss from one or more of these medications, you should consult with your doctor and hearing specialist to discuss any possible alternative medications.
