How does sudden hearing loss happen? Hearing loss can be frustrating and disruptive, making it difficult to communicate and engage with the world around you. In many cases, hearing loss develops gradually over time and may become more noticeable as we age.
However, hearing loss can sometimes occur suddenly, leaving you unable to hear clearly in one or both ears. This can be frightening, especially when there is no obvious explanation for the change.
Ask yourself the following questions:
- Are you experiencing sudden hearing loss?
- Did you wake up unable to hear out of one or both ears?
- Did you notice a loud “pop” or other unusual sound before your hearing changed?
If any of these situations sound familiar, you may have questions about what is happening and what to do next. Follow along as El Dorado Hearing explains sudden hearing loss, its potential causes, and available treatment options.
Important: Sudden hearing loss in one or both ears is a medical emergency. If your hearing suddenly decreases, seek urgent medical evaluation today, ideally from an ear, nose, and throat (ENT) specialist. Do not wait for the symptoms to resolve on their own.
How Does Sudden Hearing Loss Happen?
Sudden hearing loss refers to a rapid decrease in hearing that develops over a short period, often within 72 hours. It commonly affects one ear, although both ears can be affected in some cases.
One important type is sudden sensorineural hearing loss (SSNHL), which occurs when there is a problem with the inner ear or the auditory pathways that transmit sound information to the brain. It may develop without warning, and the cause often remains unknown even after medical evaluation.
Sudden hearing loss can also result from problems affecting the outer or middle ear, such as earwax blockage, fluid buildup, or a damaged eardrum. These conditions require different treatments, so prompt examination is essential to identify the cause.
Although some people recover partially or completely, sudden hearing loss should never be assumed to be harmless. Delayed diagnosis or treatment can reduce the chance of recovery, and some cases result in permanent hearing loss.
Causes of Sudden Hearing Loss
Unlike hearing loss associated with aging or long-term noise exposure, sudden hearing loss develops rapidly. Possible causes include:
- Viral or other infections: Certain infections may affect the inner ear or auditory pathways.
- Changes in blood flow: Problems affecting the blood supply to the inner ear may contribute to sudden hearing changes, although the precise cause is often difficult to establish.
- Inner ear disorders: Conditions affecting the inner ear can cause hearing changes, sometimes accompanied by dizziness, tinnitus, or a feeling of fullness in the ear.
- Autoimmune conditions: In some cases, the immune system may mistakenly attack structures in the inner ear, affecting hearing.
- Head or ear injuries: Trauma, pressure changes, or damage to the eardrum or inner ear may cause sudden hearing loss.
- Medication effects: Certain medications can damage hearing, particularly when they affect the inner ear.
- Neurological or vascular conditions: Rarely, sudden hearing loss may be associated with a stroke or another serious medical condition.
- Growths affecting the hearing nerve: A vestibular schwannoma or another uncommon condition may contribute to hearing loss, although these problems more often cause gradual changes.
In many cases of sudden sensorineural hearing loss, no specific cause is identified. Because some causes require urgent treatment, a healthcare professional should evaluate sudden hearing changes rather than attempting to diagnose the problem at home.
Sudden Hearing Loss Treatment Options
Treatment for sudden hearing loss depends on its cause. A healthcare professional will examine your ears and may arrange a hearing test to determine the type and severity of the hearing loss. Additional tests may be recommended when necessary.
For sudden sensorineural hearing loss, corticosteroids are a common treatment option. They may be prescribed orally or administered through an injection into the middle ear, allowing the medication to reach the inner ear. Treatment decisions depend on individual circumstances, and steroids do not guarantee that hearing will return to normal.
If initial treatment does not fully restore hearing, an ENT specialist may recommend additional treatment, such as intratympanic steroid injections. Hyperbaric oxygen therapy combined with steroid treatment may also be considered in selected cases, depending on the timing and availability of treatment.
If the hearing loss is caused by earwax blockage, fluid, an eardrum injury, or another identifiable problem, treatment will focus on addressing that underlying cause.
Timing matters. For suspected sudden sensorineural hearing loss, treatment is generally most beneficial when started as early as possible. Steroid treatment is often considered within the first two weeks after symptoms begin, and additional treatment may be recommended when recovery is incomplete. Do not delay urgent assessment while waiting to see whether your hearing improves.
Not everyone regains their hearing completely after sudden hearing loss. An ENT specialist and audiologist can explain your treatment options, monitor your recovery, and discuss hearing rehabilitation if needed.
