What is the primary risk associated with mastoiditis?

Mastoiditis is an inflammation or infection of the mastoid bone, which is located behind the ear. One of the primary risks associated with mastoiditis is the potential development of meningitis, which is an infection of the protective membranes covering the brain and spinal cord. This serious condition can occur because the mastoid is closely situated to the brain and any bacteria from an infected mastoid cavity can spread to the meninges, leading to inflammation and infection.

The risk of meningitis being a primary concern highlights why timely treatment of mastoiditis is crucial. If left untreated, it can result in severe complications that directly affect the central nervous system, making it a medical emergency.

Hearing loss, vertigo, and fluid retention can also be associated with mastoiditis; however, they are generally considered secondary concerns related to the condition. While they can significantly impact a patient's quality of life and indicate the severity of the condition, they do not pose the same immediate and life-threatening risks as meningitis does.
