Labyrinthitis: Causes, Symptoms, Diagnosis and Treatment

Article by Jennifer Lee, Senior Clinical Audiologist at Hearing Partners

Labyrinthitis can seriously affect hearing and balance when the inner ear becomes inflamed. In severe cases, it may lead to lasting complications such as chronic dizziness or irreversible hearing loss. Although it can occur at any age, labyrinthitis is more common among individuals between 30 and 60.

This article outlines the key causes, symptoms, diagnosis, and treatment options for labyrinthitis, along with essential self-care and prevention tips to support recovery and ear health.

Labyrinthitis is inflammation of the inner ear labyrinth, the structure responsible for both hearing and balance. When this part of the ear becomes inflamed, it disrupts the signals sent from the inner ear to the brain, leading to symptoms such as tinnitus, vertigo, and hearing loss. Vertigo causes individuals to feel as though the room is spinning even when they are standing still.

There are two main types of labyrinthitis: viral and bacterial. Viral labyrinthitis is usually caused by viruses responsible for the common cold, flu, measles, or mumps. Symptoms tend to appear suddenly and often affect only one ear.

On the other hand, bacterial labyrinthitis occurs when bacteria spread from a middle ear infection to the inner ear. This type produces more severe symptoms, including intense vertigo, vomiting, and tinnitus (ringing in the ear). Neither form of labyrinthitis is contagious, and a doctor can determine which type is present through examination and testing.

While labyrinthitis typically clears on its own within a few weeks, some individuals may continue to experience balance problems for a longer period.

Most cases of labyrinthitis develop after viral infections, such as colds or influenza. Bacterial infections, including meningitis or middle ear infections, can also lead to inflammation of the inner ear. In some cases, autoimmune disorders or certain medications may trigger the condition.

Several lifestyle and health factors can increase the risk of developing labyrinthitis, including:

• Smoking and alcohol use
• Stress and fatigue
• A history of allergies
• Poor hand hygiene during cold and flu season

Labyrinthitis often begins suddenly, with symptoms that worsen over the first day. Common signs include:

• Vertigo (a spinning sensation)
• Dizziness and loss of balance
• Nausea and vomiting
• Hearing loss 
• Tinnitus (ringing in the ear)
• Blurred vision or difficulty focusing
• Ear pressure or pain in some cases

Symptoms are typically most severe for several days, then gradually improve within one to three weeks as the inflammation subsides.

Although vestibular neuritis and labyrinthitis both involve the inner ear and affect balance, they differ in the part of the ear that becomes inflamed. Labyrinthitis affects the fluid-filled structure that contains both the hearing and balance organs. Vestibular neuritis, on the other hand, is inflammation of the vestibular nerve, which carries balance signals from the inner ear to the brain.

Because of this distinction, the two conditions share similar symptoms such as dizziness and vertigo, but hearing loss and tinnitus occur only in labyrinthitis. In vestibular neuritis, hearing remains normal since the cochlea, the part responsible for hearing, is not affected.

You should seek medical attention immediately if you experience a sudden onset of vertigo and/or hearing loss. Prompt diagnosis and treatment are important to prevent complications such as permanent hearing loss or chronic balance problems.

A doctor diagnoses labyrinthitis through a combination of physical and neurological examinations. These may include:

• Otoscope examination to look for signs of ear infection
• Hearing tests to assess auditory function
• Eye movement assessments to detect balance-related abnormalities
• CT or MRI scans to rule out serious conditions like a stroke or brain tumour
• Blood tests to check for infections

An early diagnosis helps ensure appropriate treatment and supports a faster, smoother recovery. If you experience any warning symptoms, please head to an Ear, Nose and Throat (ENT) specialist as soon as possible.

Treatment depends on whether the cause is viral or bacterial. Viral labyrinthitis is managed with symptomatic relief, as antibiotics are ineffective against viruses. Medications such as antihistamines, motion-sickness tablets, or corticosteroids may be prescribed for short-term symptom relief. In cases of bacterial labyrinthitis, antibiotics are necessary to treat the underlying infection.

If balance issues continue after recovery, vestibular rehabilitation therapy (physiotherapy) can help retrain the brain and improve stability. Across the treatment process, it is important to follow your doctor’s instructions and avoid driving or operating machinery while feeling dizzy to ensure safety during recovery.

If hearing loss and/or tinnitus persist after recovery, a hearing aid or tinnitus masker may be necessary to reduce listening difficulties, maintain sound awareness on the affected side and listening balance between the two ears.
