Otology antibiotics overview
Otitis externa
Infection of the soft tissue of external ear canal which can be bacterial or fungal. Oral antibiotics are rarely needed as they have poor penetration. Topical antibiotics more suited unless systemic illness.
Otitis media
Bacterial infection of the middle ear. An oral antibiotic may be used (ABMU guidelines state if no improvement after 72 hours of no treatment). Some evidence of antibiotic resistance developing.
Otitis media with perforated tympanic membrane
Consider antibiotic ear drops with/without steroid, sometimes in combination with oral.
