| Brief outline/clinical setting | Infection of the temporal bone (mastoid), is typically a complication of acute otitis media. Distinction must be made between clinical and radiographic mastoiditis. Clinical disease presents with otalgia, headache, fever and results in Post auricular skin changes, Mastoid tenderness, Auricular protrusion, Fullness of the posterior superior EAC skin, Peripheral blood leukocytosis Systemic toxicity(ie, fever lethargy etc). |
| Aetiologies/organisms |
If previously treated AOM, 30% to 50% of patients will be culture negative
|
| Optimal antimicrobial selection |
After identification of the organism, antibiotic coverage can be narrowed. Patients should be afebrile for 48 hours before intravenous antibiotics are discontinued. Oral antibiotics should then be administered for an additional 14 days. |
| Duration | 2 weeks |
