What is labyrinthitis?
Labyrinthitis is a disorder of the inner ear that occurs when one of the vestibular nerves becomes inflamed. The vestibular nerves, which reside in the inner ear, send information to your brain to control balance.
Types of labyrinthitis
There are two types of labyrinthitis:
Viral labyrinthitis
Viral labyrinthitis is more common than bacterial labyrinthitis and typically only affects one ear. It has been linked to measles, mumps, hepatitis, herpes simplex II, chicken pox and shingles. Although symptoms may subside quickly with viral labyrinthitis, it can come back without warning.
Bacterial labyrinthitis
Bacterial labyrinthitis can be caused when bacteria gets into the inner ear and causes inflammation or from an infection in the bones surrounding the inner ear.
Causes of labyrinthitis
There are several causes of labyrinthitis, including:
- Stomach virus
- Herpes virus
- Bronchitis, influenza or other respiratory illnesses
- Inner ear infections
- Bacterial middle ear infections
Risk factors for labyrinthitis
You are at greater risk of developing labyrinthitis if you:
- Are a smoker
- Have allergies or a history of allergies
- Take prescription or over-the-counter medications
- Are under major stress or are extremely fatigued
Symptoms of labyrinthitis
Symptoms of labyrinthitis include:
- Dizziness
- Nausea
- Loss of hearing
- Vertigo
- Loss of balance
- Nausea and vomiting
- Tinnitus (ringing or buzzing in the ear)
- Loss of hearing in one ear
- Inability or difficulty focusing your eyes
- Permanent hearing loss
Symptoms can occur suddenly without warning. If you are having trouble with balance, vision or feel lightheaded, call your doctor right away.
Diagnosis of labyrinthitis
Your Mercy Health doctor may be able to diagnose labyrinthitis during a physical examination. Because symptoms of labyrinthitis are similar to other ear conditions such as Meniere’s disease, migraines, a minor stroke, a brain hemorrhage or benign paroxysmal positional vertigo, your doctor may also order tests to rule these conditions out.
Your doctor may order the following tests:
- Hearing test
- Neurological exam
- Blood tests
- CT or MRI scan — takes images of the brain
- Electroencephalogram (EEG) — tests brain waves
- Electronystagmography (ENG) — tests eye movement
Treatments for labyrinthitis
Depending on the cause of your symptoms, your doctor may prescribe one of the following treatment options:
Medical management
Medications that may help relieve your symptoms include:
- Prescription and over-the-counter antihistamines
- Sedatives
- Corticosteroids
- Antibiotics (if you have a current infection)
- Medications that relieve nausea and dizziness
Movement changes
There are several movement changes you can try to relieve the symptoms of vertigo such as:
- Avoid any sudden body movements or changes in position.
- Get up slowly from a sitting or lying down position to give your blood pressure time to adjust.
- Avoid moving during a vertigo attack.
- Stay away from computer screens, flashing lights or television during a vertigo episode.
- If you are lying down when an episode starts, move to a sitting position in a chair. Use low lighting instead of bright lights or complete darkness.
Balance exercises
Your doctor may recommend using a physical therapist to teach you exercises that can improve your balance.
