How does mastoiditis develop?

ANSWER

Mastoiditis most often develops as a result of a middle ear infection. Bacteria from the middle ear can travel into the air cells of the mastoid bone. In addition, a type of skin cyst in the middle ear, called a cholesteatoma, may block drainage of the ear, leading to mastoiditis.
