Key points:
1. Post-operative fever after cortical mastoidectomy due to complicated
acute mastoiditis may be a benign sign in duration of 5-6 days post
operatively.
2. In cases of multiple acute mastoiditis complications, higher and
prolonged fever is more likely, compared to single complication cases.
3. S. pneumoniae is the common pathogen in patients with single
acute mastoiditis complication, while F. necrophorum is
associated with multiple complications.
