Overview
Acute mastoiditis infection of the temporal bone mostly after otitis media of less than one month. Mucosa lining the middle ear and also mastoid air cell becomes inflamed in the setting of acute otitis media. Most of cases the infection will resolve, but some times it will persist, and bacteria and fluid can accumulate within the mastoid air cells. With increasing pressure mastoid air cells may be damaged.[1][2]
Pathogenesis
- Most common bacteria causing acute Mastoiditis Streptococcus pneumoniae, Streptococcus pyogenes, and Staphylococcus aureus
- Staphylococci, Pseudomonas spp. and polymicrobials present predominantly seen in non-acute Mastoiditis.[3]
- Pseudomonas aeruginosa may be find in children with acute mastoiditis as a consequence of recurrent acute otitis media and antibiotic use[3]
