Causes
Mastoiditis typically develops from an untreated middle ear infection (otitis media) that spreads to the mastoid bone. Let’s explore some of the main causes:
Middle Ear Infection (Otitis Media)
A bacterial or viral infection in the middle ear can spread to the mastoid bone if not properly treated, leading to mastoiditis. This is the most common cause of the condition. Learn more about Middle ear infection (otitis media).
Cholesteatoma
It’s an abnormal collection of skin cells behind the ear drum in the middle ear, which can affect the structures of the middle ear and even the mastoid bone.
Chronic Ear Infections
Repeated or persistent ear infections can damage the ear structures and increase the risk of developing mastoiditis. This is why prompt and thorough treatment of ear infections is crucial.
Trauma
Physical injury to the ear or head can potentially lead to infection and mastoiditis if not adequately treated. Such injuries may create a pathway for bacteria to enter and infect the mastoid bone.
Immune System Disorders
Individuals with weakened immune systems are more susceptible to infections, including those that can lead to mastoiditis. This is because their bodies may struggle to fight off the initial ear infection effectively.
