(1) Acute otitis media is likely in adults with recent-onset otalgia, fever, and a bulging eardrum on otoscopy. Management is similar to that in children: no antibiotics in the first instance, then amoxicillin later if antibiotic therapy is needed. (2) Otitis media with a perforated eardrum, and evidence of pus must be distinguished from external otitis. In patients with otitis media and a perforated eardrum, the commonest bacterial isolates are staphylococci, pseudomonas and pneumococci. (3) If antibiotics are prescribed the choice of agent is based on individual clinical findings and underlying health status.
