WHAT IS IT?
Labyrinthitis is an infection of the labyrinth, the fluid-filled chamber of the inner ear that controls balance and hearing.
The infection often results from the spread of bacteria from acute otitis media, viral illness or meningitis.
HOW IS IT DIAGNOSED?
History: The individual may report symptoms of hearing loss in one ear, nausea, and a sensation of spinning (vertigo). A history of recent otitis media and upper respiratory infection is often described.
Physical exam may be normal or may show signs of upper respiratory infection. The neurological exam will show abnormal eye movements (
nystagmus) and loss of hearing in one ear.
Tests: Audiometric testing and other studies may be needed to determine any underlying disorder.
If drainage from the ear is present, a sample may be sent to the lab to determine if there is an infection.
HOW IS IT TREATED?
Antibiotics are used if labyrinthitis is due to a bacterial infection.
Antinausea drugs and sedatives are used to control symptoms.
The individual may need to rest in bed for several days.
WHAT MIGHT COMPLICATE IT?
Labyrinthitis may spread and be a precursor to
meningitis. Permanent hearing loss is possible on the affected side.
PREDICTED OUTCOME
The severe symptoms of vertigo usually pass within a few days to a week.
Feelings of imbalance may persist for several weeks or even months, particularly with quick movements.
Return to normal function depends on the speed and efficacy of treatment.
In some cases, inflammation may cause severe damage within the labyrinth and result in permanent hearing loss.
ALTERNATIVES
Vertigo and
Meniere's disease present similarly.
