Ménière’s Diesease2Description of PathologyMénière’s disease is a disease that occurs in the labyrinth, a compartment of the inner ear.It is caused by fluid build-up in the inner ear, usually only one ear. The fluid build-up causes amiscommunication to the brain about the body’s balance and hearing, therefore causing severedizziness attacks, hearing loss, ear congestion, and a ringing noise in the ears. It primarily affectspatients aging from mid-forties to early sixties but could happen to anyone at any age. Accordingto the National Institute on Deafness and Other Communication Disorders (NIDCD), there areabout 45,500 cases of Ménière’s Disease reported each year in the United States. There iscurrently about 0.2% of the United States population that has it(Meniere’s Disease, 2019).Although there are many theories about the cause of Ménière’s disease, the real cause isunknown. This means that there is, unfortunately, no cure. That doesn’t mean that patients withMénière’s disease suffer through it forever. Some different medications and therapies help toalleviate symptoms, as well as dietary restrictions. Although Ménière’s disease is not fatal, it cancause total hearing loss. Usually, however, a patient will undergo surgery to prevent that.Normal Anatomy of the Inner EarThe inner ear is quite complex in structure and arguably the most crucial part because itcontains many sensory receptors. It is made up of a bunch of little canals called the labyrinth.The labyrinth separates into two regions within the inner ear: the bony labyrinth and themembranous labyrinth. The structure that separates the middle ear from the inner ear is called theoval window (King, 2010). The oval window is crucial because it is the beginning of the bonylabyrinth. There is also a flexible structure that keeps the opening closed, when necessary, calledthe stapes. The bony labyrinth is made up of the semicircular canals, which act as a protector for
