What Is The Difference Between Vestibular Neuritis And Labyrinthitis

Vestibular neuritis and labyrinthitis are often confused due to their similar symptoms, but they are distinct conditions affecting the inner ear. Both conditions can cause dizziness, vertigo, and balance issues, but their causes and treatments differ. Understanding these differences is crucial for effective diagnosis and management.

Vestibular neuritis is an inflammation of the vestibular nerve, primarily causing vertigo and balance problems without affecting hearing. In contrast, labyrinthitis involves inflammation of both the vestibular and cochlear nerves, leading to vertigo and hearing loss. Recognizing these distinctions helps in tailoring appropriate treatment plans.

The inner ear’s vestibular system plays a key role in maintaining balance and spatial orientation. When this system is disrupted, as in vestibular neuritis or labyrinthitis, the effects can be debilitating. Proper diagnosis and timely treatment are essential to alleviate symptoms and prevent complications.


Viral Infections

Viral infections are the most common cause of both vestibular neuritis and labyrinthitis. These conditions often occur following a respiratory or gastrointestinal infection. Viruses can travel from these areas to the inner ear, causing inflammation.

  • Herpes simplex virus: This virus is frequently associated with vestibular neuritis. It lies dormant in the body and can reactivate, leading to inflammation of the vestibular nerve.
  • Influenza virus: Common flu viruses can lead to labyrinthitis. When the body fights off the flu, the virus can sometimes migrate to the inner ear.
  • Varicella-zoster virus: This virus, which causes chickenpox and shingles, can also cause inner ear infections.
  • Measles and mumps viruses: These childhood diseases, though less common now due to vaccinations, can cause labyrinthitis if they reach the inner ear.

The mechanism by which these viruses cause inflammation is similar. The body’s immune response to the viral infection results in swelling and damage to the nerves involved.

Bacterial Infections

Bacterial infections are less common than viral infections but can be more severe. They often result from a middle ear infection (otitis media) spreading to the inner ear.

  • Streptococcus pneumoniae: This bacterium is a common cause of middle ear infections and can spread to the inner ear, causing labyrinthitis.
  • Haemophilus influenzae: Another bacterium that can cause middle ear infections and subsequent inner ear inflammation.
  • Meningitis: Bacterial meningitis can spread to the inner ear, causing severe labyrinthitis. The bacteria from the cerebrospinal fluid can travel to the inner ear, leading to significant inflammation.

Bacterial labyrinthitis often requires more aggressive treatment compared to viral labyrinthitis. Prompt antibiotic therapy is crucial to prevent complications.

Other Possible Causes

While viral and bacterial infections are the primary causes, other factors can also lead to vestibular neuritis and labyrinthitis.

  • Autoimmune diseases: Conditions like lupus and rheumatoid arthritis can cause the immune system to attack the inner ear, leading to inflammation.
  • Allergic reactions: Severe allergies can cause inflammation in the inner ear, resulting in symptoms similar to vestibular neuritis and labyrinthitis.
  • Head injuries: Trauma to the head can damage the inner ear structures, leading to inflammation and symptoms.
  • Tumors: Acoustic neuromas, benign tumors on the vestibular nerve, can cause symptoms similar to vestibular neuritis.

Vestibular Neuritis Symptoms


Vertigo is the hallmark symptom of vestibular neuritis. It involves a sudden, intense spinning sensation that can last for hours or even days. Vertigo can be debilitating, causing difficulty with movement and coordination. Patients often describe feeling like the world is spinning around them.

  • Severe spinning: The sensation can be so strong that it makes standing or walking difficult.
  • Positional triggers: Moving the head or changing positions can worsen the vertigo.
  • Duration: Episodes can last from a few hours to several days, and in some cases, weeks.

Nausea and Vomiting

Nausea and vomiting are common due to the severe vertigo experienced in vestibular neuritis. The brain receives conflicting signals from the inner ear, leading to these symptoms.

  • Nausea: A constant feeling of sickness in the stomach, often linked with dizziness.
  • Vomiting: Frequent vomiting can occur during severe vertigo episodes, leading to dehydration.

Balance Issues

Balance issues arise because the vestibular nerve is responsible for sending balance information from the inner ear to the brain. Inflammation disrupts these signals.

  • Unsteadiness: Patients often feel unsteady on their feet and may stumble or fall.
  • Difficulty walking: Walking in a straight line or maintaining balance while standing can be challenging.
  • Coordination problems: Performing tasks that require fine motor skills can become difficult.

Labyrinthitis Symptoms

Hearing Loss

Hearing loss is a primary symptom of labyrinthitis, setting it apart from vestibular neuritis. Inflammation affects both the vestibular and cochlear nerves, leading to hearing issues.

  • Partial or complete loss: Hearing loss can range from mild to severe and may affect one or both ears.
  • Sudden onset: Hearing loss often occurs suddenly and can be alarming.
  • Tinnitus: Ringing or buzzing in the ears often accompanies hearing loss.


Tinnitus is the perception of noise or ringing in the ears in the absence of external sound. It is a common symptom in labyrinthitis due to inflammation affecting the cochlear nerve.

  • Ringing or buzzing: Patients may hear continuous ringing, buzzing, or hissing sounds.
  • Varying intensity: The loudness of the tinnitus can vary, sometimes becoming more pronounced in quiet environments.

Vertigo and Balance Issues

Labyrinthitis also causes vertigo and balance issues similar to vestibular neuritis, but these symptoms are accompanied by hearing loss.

  • Severe vertigo: Intense spinning sensation similar to vestibular neuritis.
  • Balance problems: Difficulty maintaining balance, leading to unsteadiness and falls.
  • Coordination difficulties: Problems with fine motor skills and performing everyday tasks.


Medical History

A detailed medical history is the first step in diagnosing vestibular neuritis and labyrinthitis. Doctors will ask about recent illnesses, the onset of symptoms, and their severity.

  • Recent infections: History of respiratory or gastrointestinal infections can indicate a viral cause.
  • Symptom timeline: Understanding when symptoms started and their progression helps in diagnosis.
  • Medical conditions: Existing conditions like autoimmune diseases can provide clues.

Physical Examination

During a physical examination, doctors assess balance, coordination, and hearing. They look for signs that can differentiate between vestibular neuritis and labyrinthitis.

  • Balance tests: Walking in a straight line, standing on one foot, or other balance tests.
  • Coordination tests: Finger-to-nose test or other tasks to assess fine motor skills.
  • Hearing tests: Checking for hearing loss and tinnitus.
