The middle ear is the space behind the eardrum, which is connected to the back of the throat by a passageway called the Eustachian tube. Middle ear infections, also called otitis media, can occur when congestion from an allergy or cold blocks the Eustachian tube. Fluid and pressure build up, so bacteria or viruses that have traveled up the Eustachian tube into the middle ear can multiply and cause an ear infection.
Inner ear disorders are common and patients with vestibular failure often present to a neurology clinic because of their dizziness, gait unsteadiness and oscillopsia. Vestibular disorders can be divided into peripheral and central vestibular disorders. Most of the peripheral vestibular disorders have a clinical diagnosis, and a thorough history and examination will often provide a clear direction as to the diagnosis.
Back to Health A to Z. It causes a delicate structure deep inside your ear called the labyrinth to become inflamed, which affects your hearing and balance. The symptoms of labyrinthitis can be quite severe during the first week, but usually get better after a few weeks. In some cases, the symptoms can last longer and have a significant impact on your quality of life and ability to carry out everyday tasks.
A middle ear infection occurs behind the eardrum. It is most often caused by a virus or bacteria. Most kids have at least one middle ear infection by the time they are 3 years old.
Chronic ear infections, also called chronic otitis media, is an inflammation or infection of the middle ear. Chronic means recurring or persistent. Inflammation or infection of the middle ear occurs when the eustachian tube to that ear is blocked.
The inner ear is in the petrous area of the temporal bone. Within the bone is the osseous labyrinth, which encases the membranous labyrinth. The osseous labyrinth includes the vestibular system made up of the semicircular canals and the vestibule and the cochlea.
Ear infections may be more common in children than in adults, but grown-ups are still susceptible to these infections. Unlike childhood ear infections, which are often minor and pass quickly, adult ear infections are frequently signs of a more serious health problem. There are three main types of ear infections. They correspond to the three main parts of the ear: inner, middle, and outer.
Ear infections are one of the most common reasons parents take their children to the health care provider. The most common type of ear infection is called otitis media. It is caused by swelling and infection of the middle ear.
Vestibular neuritis and labyrinthitis are disorders resulting from an infection that inflames the inner ear or the nerves connecting the inner ear to the brain. This inflammation disrupts the transmission of sensory information from the ear to the brain. Vertigo, dizziness, and difficulties with balance, vision, or hearing may result.
