Overview
Acute mastoiditis is the infection of the temporal bone that occurs after otitis media of less than one month. Mucosa lining the middle ear and also mastoid air cells becomes inflamed in the setting of acute otitis media. Most cases of the infection resolve, but some persist leading to bacterial and fluid accumulation within the mastoid air cells. With increasing pressure, mastoid air cells may be damaged.[1][2] Most common bacteria causing acute mastoiditis Streptococcus pneumoniae, Streptococcus pyogenes, and Staphylococcus aureus.
Pathogenesis
...
- The mucosa that lines the middle ear and the mastoid air cells become inflamed in the setting of acute otitis media.
- The most common bacteria that cause acute mastoiditis are Streptococcus pneumoniae, Streptococcus pyogenes, and Staphylococcus aureus. [3]
- Staphylococci, Pseudomonas spp. and polymicrobials present predominantly seen in non-acute Mastoiditis.[4]
- Pseudomonas aeruginosa may be find in children with acute mastoiditis as a consequence of recurrent acute otitis media and antibiotic use[4]
