Otitis media is defined as a group of inflammatory conditions that affect the middle ear cleft; it consists of acute otitis media (AOM), otitis media with effusion, and chronic otitis media. These terms are often used interchangeably, but should be differentiated from one another by their clinical signs and symptoms, as well as the duration of disease, to ensure the correct diagnosis is reached. Correct diagnosis enables appropriate management of patients within the community, including urgent referral for ear, nose and throat review. This article focuses on the diagnosis and management of AOM for GPs.
