Mastoid Process: From 2 Different Sources


The large process of the temporal bone of the SKULL which can be felt immediately behind the ear. It contains numerous cavities, one of which – the mastoid antrum – communicates with the middle ear, and is liable to suppurate when the middle ear is diseased. (See under EAR, DISEASES OF.)

a nipple-shaped process on the *temporal bone that extends downward and forward behind the ear canal and is the point of attachment of several neck muscles. It contains many air spaces (mastoid cells), which communicate with the cavity of the middle ear via an air-filled channel, the mastoid antrum. This provides a possible route for the spread of infection from the middle ear (see mastoiditis).

Mastoid Bone

The lower part of the temporal bone in the skull. It has a projection, known as the mastoid process, which can be felt behind the ear. The mastoid bone is honeycombed with air cells. These are connected to a cavity called the mastoid antrum, which leads into the middle ear. Infections of the middle ear (see otitis media) occasionally spread through the mastoid bone to cause acute mastoiditis.... mastoid bone

Auditory Processing Disorder

(APD, central auditory processing disorder, CAPD) a series of conditions characterized by difficulty in hearing and processing auditory information, especially in poor acoustic environments, despite normal or near-normal ear function. It may be due to genetic factors, maturational delay in the central nervous system, or focal abnormalities of the central nervous system (such as tumours). Treatments include *hearing therapy, *auditory skills training, educational support, use of *assistive listening devices, and training with computerized therapy tools.... auditory processing disorder
