{{R to section}}

{{Authority control}}
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 ==
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.
