Labyrinthitis - Classification

Acute Labyrinthitis is an infection rinofaringiene consecutive. In this case, intense vertigo that occurs suddenly is growing progressively for 30 minutes and may be associated with vomiting, nausea, but not with signs of cochlear (hearing disorder). Under these conditions, sometimes the patient is bedridden. Signs may take several days, but generally healing occurs after a symptomatic treatment, which involves the use of antihistamines and sedatives.
Labyrinthitis is a consequence of otitis media with effusion (otitis seromucoasa), characterized by the presence of pleural fluid behind the eardrum due to accuse a patient of ear fullness and abnormal reverberation of their voices. Labyrinthitis can lead to destruction of the tympanic effusion or mastoiditis (inflammation of the mastoid - bone behind the ear).
Labyrinthitis due to chronic wear a labyrinth by cholesteatoma (benign tumors in most cases).
Viral labyrinthitis is the most common. In 50% of cases it occurs as a result of a viral infection that affects the nose and throat (cold or flu). Other viral infections - mumps virus (mumps), measles, rubella and chickenpox - are responsible.The first symptoms usually consist of mild to moderate hearing loss. Then there is a sudden loss of balance. During the acute episode, which can take 30 minutes, often causes nausea and vomiting vertigo so severe that complete bed rest is required to relieve the symptoms. Vertigo may last for several days or weeks.In general, the return hearing coincides with the healing.
Bacterial labyrinthitis is in most cases, a complication of meningitis or otitis media. It can occur in two ways: either by entering the labyrinth of the flammable liquid - in this case we speak of serous labyrinthitis, either by direct invasion of bacteria in the maze - purulent labyrinthitis. The latter, more serious, requiring surgery to stop the infection. Frequently, purulent labyrinthitis is due to a tumor of the middle ear (cholesteatoma), which allows penetration of bacteria in the inner ear.Symptoms are less severe in the case of a serous labyrinthitis caused by otitis media, often reversible without health consequences. In contrast, when the cause is represented by meningitis, both ears are affected, and severe hearing loss and are vertijele.
