What is the term for inflammation of the mastoid process behind the ear?

Mastoiditis refers specifically to the inflammation of the mastoid process, which is the bony protrusion located behind the ear. This condition typically arises as a complication following acute otitis media, an infection of the middle ear. The mastoid air cells, which are air-filled spaces within the mastoid process, can become infected, leading to swelling, pain, and potential drainage from the ear.

In this context, mastoiditis is critical because it often requires prompt medical intervention. If left untreated, it can lead to serious complications, such as the spread of infection to surrounding structures, including the brain. Understanding mastoiditis is essential for clinical practice in ENT, as recognizing its signs and symptoms allows for timely diagnosis and management. The other terms, while related to ear pathology, refer to different conditions and do not specifically describe inflammation of the mastoid process.
