Mastoid process
Mastoid Process
The Mastoid Process (pronunciation: /ˈmæstɔɪd ˈprɒsɛs/) is a conical prominence of the Temporal Bone located just behind the ear. The term "mastoid" is derived from the Greek word "mastoeides", meaning "breast-shaped".
Anatomy
The Mastoid Process is filled with air cells that communicate with the Middle Ear. It provides a surface for the attachment of several muscles, including the Sternocleidomastoid, Splenius Capitis, and Longissimus Capitis muscles.
Clinical Significance
Infections in the middle ear can spread to the mastoid process, leading to a condition known as Mastoiditis. This can cause serious complications if not treated promptly, including hearing loss and meningitis.
