Mastoid process
Mastoid Process
The Mastoid Process is a conical prominence projecting from the undersurface of the mastoid portion of the temporal bone. It is located just behind the external ear. The mastoid process provides a surface for the attachment of several muscles that assist in moving the head.
Anatomy[edit | edit source]
The mastoid process is filled with air cells that communicate with the middle ear, known as the mastoid cells. These cells are susceptible to infection, which can lead to a condition known as mastoiditis. The mastoid process is also the site of insertion for the sternocleidomastoid muscle, which is responsible for rotating the head.
Clinical Significance[edit | edit source]
The mastoid process can be easily palpated, which makes it a useful landmark in medical examinations. Infections in the mastoid process can lead to serious complications, including hearing loss and meningitis. Therefore, early detection and treatment of mastoiditis is crucial.
