Chronic Mastoid Cavity Disease
Definition: The mastoid underlies the bone directly behind the ear. It is a collection of small air cells, like sinuses, that are connected to the middle ear and are also lined with a mucous membrane. Their exact function is unknown. They can become diseased when the middle ear is diseased and can also develop chronic disease, or chronic mastoiditis. Like the middle ear, this is usually successfully treated with antibiotics, however a small percentage of people develop complications of chronic and/or acute mastoiditis and require surgical intervention. This procedure is called a mastoidectomy. One form of this procedure creates a cavity about the size of your thumb because of the elimination of the mastoid cells, and can be viewed through the ear canal. The cavity can become chronically infected because of the presence of microorganisms and water. This results in purulent foul smelling drainage, pain, and frequently increased hearing loss and dizziness. It is called Chronic Mastoid Cavity Disease. Untreated cases can progress to infection in the bone (osteomyelitis), brain abscesses, and very rarely death.
Treatment: Through cleaning of the cavity and the use of antibiotics is the primary treatment; however repeat surgical intervention is sometimes necessary.
Prevention: In cases where the mastoid bowl remains chronically moist or persistent water remains in the mastoid bowl, the regular use of the Mack's Ear Dryer ear canal drier evaporates this moisture and can significantly reduce the chance of infection. This is especially useful when a hearing aid is used in the ear. It is also essential to protect the ear from moisture. Because the opening to the ear canal and mastoid bowl is so large, most pre-molded earplugs won't form a good seal. However, because Mack's moldable silicone earplugs mold to the unique contours of any ear, those with mastoid bowls find them very useful for helping keep moisture out. The use of cotton tipped swabs or ear drying drops is not recommended.
