Sudden hearing loss, also known as sudden sensorineural hearing loss (SSNHL), is a medical emergency that requires prompt evaluation and treatment. This condition is characterized by the rapid onset of hearing loss in one or both ears, usually occurring over a period of hours to days. In this blog post, we will discuss the causes, symptoms, diagnosis, and treatment options for sudden hearing loss.

Causes of Sudden Hearing Loss

The exact cause of sudden hearing loss is often unknown, but several factors have been identified as potential triggers. These include:

  • Viral Infection: Many cases of sudden hearing loss are thought to be caused by a viral infection, such as a cold or flu.
  • Autoimmune Disorders: Autoimmune disorders, where the body’s immune system mistakenly attacks healthy tissue, can also cause sudden hearing loss.
  • Trauma: Trauma to the head or ears, such as a blow to the head or exposure to loud noise, can also cause sudden hearing loss.
  • Medications: Certain medications, such as antibiotics or chemotherapy drugs, can cause sudden hearing loss as a side effect.
  • Cardiovascular Disease: Cardiovascular disease, including high blood pressure and atherosclerosis, can reduce blood flow to the ears and cause sudden hearing loss.

Symptoms of Sudden Hearing Loss

The symptoms of sudden hearing loss can vary depending on the underlying cause of the condition. The most common symptoms of sudden hearing loss include:

  • A sudden loss of hearing in one or both ears.
  • A feeling of fullness or pressure in the ear.
  • Tinnitus, or a ringing, buzzing, or humming sound in the ear.
  • Dizziness or vertigo.
  • Difficulty hearing high-pitched sounds.
  • Difficulty understanding speech, especially in noisy environments.

Diagnosis and Treatment

If you experience any of the above symptoms, it is important to seek medical attention immediately. Your doctor will likely conduct a physical exam and hearing tests to determine the extent of your hearing loss. Other tests, such as blood tests and imaging scans, may also be necessary to identify the underlying cause of your sudden hearing loss.

The treatment for sudden hearing loss will depend on the underlying cause of the condition. In some cases, the hearing loss may be temporary and will improve on its own. However, in other cases, prompt medical intervention may be necessary to prevent permanent hearing loss.

Some common treatments for sudden hearing loss include:

  • Corticosteroids: Corticosteroids, such as prednisone, can reduce inflammation and swelling in the inner ear and help to restore hearing.
  • Antiviral Medications: Antiviral medications, such as acyclovir or valacyclovir, may be prescribed if the sudden hearing loss is caused by a viral infection.
  • Hearing Aids: Hearing aids can help to amplify sounds and improve your ability to hear.
  • Cochlear implants: If the sudden hearing loss is severe and permanent, your doctor may recommend a cochlear implant, which is a surgically implanted device that can help improve hearing.


While the underlying cause of sudden hearing loss is often unknown, there are some steps you can take to reduce your risk of developing this condition:

  • Protecting Your Ears: Wear earplugs or other hearing protection if you are exposed to loud noises, such as at concerts or in noisy workplaces.
  • Managing Cardiovascular Risk Factors: Keep your blood pressure and cholesterol levels under control, exercise regularly, and eat a healthy diet to reduce your risk of cardiovascular disease.
  • Avoiding Ototoxic Medications: If you are prescribed a medication that can cause hearing loss, talk to your doctor about alternative treatments.
