Mastoid air cells are a series of air-filled cavities in the mastoid bone, which is located behind the ear. The mastoid air cells are connected to the middle ear through the aditus ad antrum.

What do mastoid air cells connect to?

The mastoid air cells connect to the middle ear through the aditus ad antrum. The aditus ad antrum is a small opening in the mastoid bone that allows air to flow between the middle ear and the mastoid air cells.

Are mastoid air cells normal?

Yes, mastoid air cells are normal. They are present in most people and help to protect the middle ear from infection.

What causes inflammation in mastoid air cells?

Inflammation of the mastoid air cells, known as mastoiditis, can be caused by a number of things, including:

• Middle ear infection: If a middle ear infection is not treated, it can spread to the mastoid air cells.
• Trauma: A blow to the head can damage the mastoid air cells and cause inflammation.
• Immune system problems: People with certain immune system problems, such as HIV/AIDS, are more likely to develop mastoiditis.

What are mastoid air cells and the middle ear?

The mastoid air cells and the middle ear are connected through the aditus ad antrum. This connection allows air to flow between the two areas, which helps to equalize pressure and protect the middle ear from infection.

Symptoms of mastoiditis:

• Ear pain: The most common symptom of mastoiditis is ear pain. The pain may be severe and constant.
• Fever: People with mastoiditis often have a fever. The fever may be high, up to 104 degrees Fahrenheit.
• Drainage from the ear: People with mastoiditis may have drainage from the ear. The drainage may be clear, bloody, or pus-like.
• Hearing loss: People with mastoiditis may have hearing loss. The hearing loss may be temporary or permanent.

Treatment for mastoiditis

Mastoiditis is usually treated with antibiotics. In some cases, surgery may be necessary to drain the mastoid air cells.

If you have any of the symptoms of mastoiditis, it is important to see a doctor right away. Mastoiditis can be a serious infection, but it is usually treatable with antibiotics.
