Sudden Hearing Loss in One Ear: Is It a Medical Emergency?
Short answer: yes, treat it as one. If your hearing drops in one ear over a few hours or days, don’t wait to see if it clears up. Getting checked quickly gives you the best chance of getting your hearing back.
What sudden hearing loss feels like
The medical term is sudden sensorineural hearing loss (SSNHL), sometimes called sudden deafness. It’s a problem in the inner ear or the nerve that carries sound to the brain. Because it’s usually painless, many people assume they have earwax, a cold, or water in the ear, and put off getting help.
Common signs include:
- Sound that’s suddenly quieter or muffled on one side
- Trouble hearing on the phone when you switch to the affected ear
- A “pop” or feeling of fullness in the ear just before the change
- New ringing, buzzing, or roaring (tinnitus)
- Dizziness, imbalance, or a spinning sensation
If any of this sounds familiar, call us, an urgent care clinic, or an ear, nose, and throat (ENT) doctor today.
Why speed matters
Treatment for SSNHL works best when it starts early. The first job is figuring out what type of hearing loss you have:
- Conductive loss is a blockage or a problem in the outer or middle ear, such as earwax or fluid. It’s often easy to treat.
- Sensorineural loss involves the inner ear or hearing nerve and needs prompt medical care.
The two can feel nearly identical, so it takes an ear exam and a diagnostic hearing test to tell them apart. That test also shows how severe the loss is and which pitches are affected.
Call 911 if hearing loss comes with:
- Facial drooping, weakness, or numbness
- Confusion, trouble speaking, or a severe, unusual headache
- Double vision, fainting, or trouble walking
- Chest pain or other signs of a serious medical emergency
These can point to a stroke or another urgent condition, and they shouldn’t wait for an office visit.
What causes it?
Most of the time, no cause is ever found. When one is, it’s usually one of these:
- A viral or bacterial infection
- Head injury or exposure to a very loud blast
- An autoimmune condition affecting the inner ear
- Medications that can harm hearing (ototoxic drugs)
- Reduced blood flow to the inner ear
- Ménière’s disease
- Multiple sclerosis
- A benign tumor pressing on the hearing nerve (vestibular schwannoma)
You can’t tell these apart by symptoms alone, which is why testing quickly is so important.
How it’s treated
Corticosteroids are the main treatment for SSNHL when no other cause is found. They can be taken as pills or given as an injection through the eardrum (intratympanic) so the medicine reaches the inner ear directly. Your provider chooses an approach based on how long ago the loss began, your test results, and your overall health.
Steroids work best when started within roughly the first two weeks, and the sooner the better. If pills don’t restore enough hearing, injections may be used as a follow-up. In some cases an ENT may also recommend hyperbaric oxygen therapy alongside steroids.
Can it get better on its own?
Sometimes. About half of people recover some or all of their hearing without treatment, usually within the first one to two weeks. The problem is that no one can predict early on who will recover, how much will come back, or whether it will last.
Waiting and hoping is a gamble. Treatment loses effectiveness as weeks pass, and the window to help can close for good.
If your hearing doesn’t fully return
Even if treatment doesn’t restore everything, you have options. Your next steps depend on how much usable hearing remains and what further testing shows. We may recommend an MRI of the inner ear canal or an auditory brainstem response (ABR) test to check the hearing nerve.
Options for living well with one-sided hearing loss include:
- Traditional hearing aids, if the ear still has usable hearing
- CROS systems, which send sound from the affected ear to your better ear
- Bone-conduction or bone-anchored devices, for those who qualify
- Cochlear implant evaluation, for profound one-sided deafness
- Assistive listening devices for work, school, or conversations
Audiologic rehabilitation can also help with listening fatigue, telling where sounds come from, and keeping up in conversations. The best choice depends on your test results, lifestyle, health history, and goals.
