Complications of otitis media

WithDuncan Bowyer

Complications of otitis media occur when infection and/or inflammation spread outside of the confines of the middle ear cleft or involve intratemporal structures such as the labyrinth or facial nerve. They are typically subclassified as either extracranial or intracranial (Table  45.1). Both acute otitis media (AOM) and chronic otitis media (COM) may lead to complications; in the pre-antibiotic era approximately half of cases were associated with AOM; today in the developed world the majority arise on a background of COM.
