What Is Autoimmune Inner Ear Disease?
Written by Medicover Team and Medically Reviewed by Dr Prerit Rao , ENT
Autoimmune Inner Ear Disease (AIED) is a rare condition in which the body's immune system mistakenly attacks the inner ear, leading to progressive hearing loss and, in some cases, balance issues. It often affects both ears and can worsen over weeks or months.
AIED can occur alone or as part of a broader autoimmune disorder, such as systemic lupus erythematosus (SLE) or rheumatoid arthritis. Early diagnosis and treatment are crucial for preserving hearing and managing symptoms.
If left untreated, AIED may lead to permanent hearing damage. Treatment typically involves corticosteroids or other immune-suppressing medications to control the immune response.
What Are the Causes of Autoimmune Inner Ear Disease (AIED)?
Autoimmune Inner Ear Disease occurs when the body's immune system mistakenly targets its inner ear tissues, leading to inflammation and hearing damage. While the exact reason behind this immune malfunction isn't always apparent, several potential causes and risk factors have been identified.
Common Causes of AIED
- Autoimmune Response: The immune system mistakenly attacks proteins in the inner ear, mistaking them for harmful invaders.
- Systemic Autoimmune Disorders: AIED may develop alongside conditions like:
- Rheumatoid arthritis
- Systemic lupus erythematosus (SLE)
- Wegener's granulomatosis
- Polyarteritis nodosa
- Genetic Susceptibility: Individuals with a family history of autoimmune diseases may be at a higher risk of developing AIED.
- Unknown Triggers: In some idiopathic cases, no clear cause is found, though immune dysfunction is still suspected.
Risk Factors of AIED
- Existing Autoimmune Disease: Individuals with autoimmune disorders are at greater risk of inner ear involvement.
- Middle-Aged Adults: Most cases are seen in people between 30 and 60 years of age.
- Female Gender: Autoimmune conditions, including AIED, are more common in women.
- Environmental Triggers: Infections or exposure to certain medications might trigger an immune response that targets the inner ear.

Autoimmune Inner Ear Disease (AIED) typically causes progressive hearing loss and balance issues, which may affect one or both ears. The symptoms often develop over weeks or months and may fluctuate.
Common Symptoms of AIED
- Bilateral Sensorineural Hearing Loss: Gradual or sudden hearing loss in both ears is the hallmark symptom.
- Tinnitus: Ringing, buzzing, or hissing sounds in one or both ears.
- Vertigo or Dizziness: A sensation of spinning or imbalance due to inner ear inflammation.
- Ear Fullness or Pressure: A sensation of fullness similar to having water or wax in the ears.
- Fluctuating Hearing: Hearing may come and go or worsen over time.
Severe or Advanced Symptoms
- Complete Deafness: If left untreated, AIED can lead to permanent hearing loss.
- Chronic Balance Problems: Severe unsteadiness may interfere with walking or daily activities.
- Associated Autoimmune Symptoms: Some individuals also experience fatigue, joint pain, or other signs of systemic autoimmune diseases, such as lupus or rheumatoid arthritis.
How Is Autoimmune Inner Ear Disease (AIED) Diagnosed?
Diagnosing Autoimmune Inner Ear Disease (AIED) can be challenging because its symptoms overlap with many other ear disorders. There's no single test to confirm AIED, so doctors rely on a combination of medical history, hearing tests, and lab investigations.
Key Diagnostic Steps for AIED
Medical History and Symptom Review
- Doctors assess the pattern and progression of hearing loss, vertigo, and any signs of autoimmune conditions (like joint pain or fatigue).
- A history of autoimmune disease increases suspicion.
Audiometry (Hearing Test)
- Measures the type and degree of hearing loss.
- AIED typically shows bilateral sensorineural hearing loss (affecting the inner ear or nerve pathways).
Blood Tests
- Autoimmune markers, such as ANA (antinuclear antibodies), ESR (erythrocyte sedimentation rate), and rheumatoid factor, may be elevated.
- Specific antibodies (e.g., anti-68 kDa antibodies) may be checked, although this is not always conclusive.
MRI Scan
- Helps rule out structural abnormalities, tumours, or infections in the inner ear or auditory nerve.
- It can detect inflammation or other inner ear damage.
Response to Steroids (Therapeutic Trial)
- A short course of corticosteroids (like prednisone) is often given.
- If hearing improves, it supports a diagnosis of AIED.
Optional Tests
- Electrocochleography (ECoG): Evaluates inner ear pressure and fluid levels.
- Vestibular testing: Assesses balance function when vertigo is a concern.
What are the Treatment Options for Autoimmune Inner Ear Disease (AIED)?
Autoimmune Inner Ear Disease is managed with medications that reduce inflammation and control the immune system. Early treatment helps prevent permanent hearing damage.
Steroid Therapy (First-Line Treatment)
- Oral steroids like prednisone are commonly used.
- They help reduce inflammation and may improve hearing.
- A positive response to steroids can support the diagnosis of AIED.
Immunosuppressive Medications
- Used when steroids alone are not effective or safe long-term.
- Common options include:
- Methotrexate
- Azathioprine
- Cyclophosphamide
- These help control immune activity and protect the inner ear.
Biologic Therapy
- Used in severe or steroid-resistant cases.
- Includes medications like rituximab or TNF inhibitors.
- These target specific immune pathways and may slow the progression of the disease.
Hearing Support
If hearing loss is permanent, supportive options include:
- Hearing aids amplify sound.
- Cochlear implants for profound hearing loss.
- Assistive listening devices provide support for daily communication.
Supportive Care
- A low-salt diet may help manage balance issues.
- Vestibular therapy is recommended if vertigo is present.
- Regular hearing tests and monitoring are crucial for adjusting treatment plans effectively.
When to See a Doctor for Autoimmune Inner Ear Disease (AIED)?
You should see a doctor promptly if you notice:
- Sudden or rapid hearing loss in one or both ears
- Unexplained ringing in the ears (tinnitus)
- Ongoing dizziness, vertigo, or imbalance
- Hearing worsens over weeks despite no ear infection
- Episodes of fluctuating hearing loss
Early diagnosis and treatment are key to preventing permanent inner ear damage.
What Questions Should I Ask My Doctor?
- What symptoms confirm that I have AIED and not another condition?
- Will my hearing improve with treatment, or is it a permanent condition?
- What treatment options are available, and which one is best for me?
- How quickly should I expect results from treatment?
- Can AIED affect both ears or just one?
- Should I be tested for other autoimmune diseases?

How Can I Prevent Autoimmune Inner Ear Disease (AIED)?
While AIED prevention isn't always possible due to its autoimmune nature, you can lower your risk and manage early signs through:
- Managing autoimmune conditions: If you already have an autoimmune disorder (like lupus or rheumatoid arthritis), follow treatment plans closely.
- Early diagnosis and treatment: Report sudden hearing loss, ear fullness, or balance issues right away.
- Avoiding ear trauma: Protect your ears from loud noises, infections, or injury, which can worsen symptoms.
- Regular checkups: Routine hearing and immune health screenings are recommended for individuals with a family history of or those at risk for autoimmune diseases.
Complications of Autoimmune Inner Ear Disease
Without timely diagnosis and care, AIED can lead to:
- Permanent hearing loss, especially if treatment is delayed.
- Balance problems that affect daily movement and safety.
- Emotional stress or depression due to hearing changes.
- Difficulty in communication and reduced quality of life.
- Involvement of both ears over time, even if symptoms start on one side.
