Labyrinthitis is an inner ear condition characterised by inflammation of the labyrinth, a structure that contains the cochlea (hearing organ) and vestibular system (balance organ). This condition disrupts both hearing and balance, causing symptoms such as dizziness, vertigo, hearing loss, and tinnitus. Prompt diagnosis and treatment can help alleviate symptoms and prevent complications.
What is Labyrinthitis?
Labyrinthitis occurs when the inner ear becomes inflamed, often due to viral or bacterial infections. The inflammation interferes with the transmission of sensory information from the inner ear to the brain, resulting in auditory and vestibular disturbances. It can affect one or both ears and varies in severity from mild to debilitating.
Symptoms of Labyrinthitis
The symptoms of labyrinthitis include a combination of auditory and vestibular effects:
- Vestibular Symptoms:
- Vertigo or dizziness, often worsened by head movements.
- Imbalance or difficulty walking.
- Nausea and vomiting.
- Auditory Symptoms:
- Hearing loss, which can range from mild to severe.
- Tinnitus (ringing, buzzing, or roaring sounds in the ear).
These symptoms may develop suddenly and persist for several days to weeks. In some cases, residual balance issues or hearing loss may linger.
How Common is Labyrinthitis?
Labyrinthitis is relatively uncommon but can occur at any age. It is more frequently associated with viral infections, such as colds or the flu, but can also result from bacterial infections, head injuries, or autoimmune conditions.
Diagnosing Labyrinthitis
Diagnosis involves a combination of clinical evaluation and tests to rule out other conditions:
- Clinical History:
- Detailed account of symptom onset, duration, and triggers.
- Identification of recent infections or illnesses.
- Physical Examination:
- Observation of nystagmus (involuntary eye movements).
- Assessment of balance and coordination.
- Audiological Tests:
- Pure-Tone Audiometry: Measures the degree of hearing loss.
- Speech Discrimination Tests: Evaluates clarity of hearing.
- Imaging Studies:
- MRI or CT scans may be used to exclude other causes of symptoms, such as stroke or tumours.
Treatment Options & Outcomes
Management of labyrinthitis focuses on relieving symptoms and addressing the underlying cause:
- Medications:
- Vestibular suppressants (e.g., meclizine) and anti-nausea drugs to reduce dizziness and nausea.
- Corticosteroids to reduce inflammation in severe cases.
- Antibiotics if a bacterial infection is suspected.
- Rest and Supportive Care:
- Adequate hydration and rest during the acute phase.
- Avoidance of rapid head movements.
- Rehabilitation:
- Vestibular Rehabilitation Therapy (VRT): Exercises to promote recovery of balance function.
Most cases of labyrinthitis resolve fully within a few weeks. However, some individuals may experience persistent hearing loss or balance issues, particularly if treatment is delayed.
Labyrinthitis is a condition that affects both hearing and balance, often resulting from infections. Early diagnosis and appropriate treatment can help resolve symptoms and minimise long-term effects. If you experience sudden vertigo, hearing loss, or tinnitus, consult a healthcare professional for timely care.
