Labyrinthitis is an inflammatory condition affecting the labyrinth in the cochlea and vestibular system of the inner ear.
Viral infections are the most common cause of labyrinthitis. Bacterial labyrinthitis is a complication of otitis media or meningitis.
Typical presentation includes vertigo, imbalance, and hearing loss.
Diagnosis is supported by history, physical exam, and audiometry.
Treatment is typically symptomatic and primarily involves the use of vestibular suppressants and antiemetics.
Labyrinthitis is an inflammatory condition caused by bacteria or viruses that affects the inner ear, which consists of the cochlea and vestibular system. Typically, it presents with sensorineural hearing loss, vertigo, and disequilibrium (problems with balance) and may affect one or both ears. It may be further classified as suppurative or serous. Suppurative (bacterial) labyrinthitis follows direct microbial invasion of the inner ear and usually presents with severe to profound hearing loss and vertigo. Serous (viral) labyrinthitis results from inflammation of the labyrinth only and usually presents with less severe hearing loss and vertigo than suppurative labyrinthitis, and the hearing loss often recovers.
