Otitis media continues to be a common and disabling problem which has become, in recent years, a fertile area for research. Based on studies in animals and humans, otitis media is classified into four groups: acute purulent otitis media (POM), serous otitis media (SOM), and mucoid or secretory otitis media (MOM). Together, these are referred to as otitis media with effusion (OME). The types can overlap and evolve into another type to become chronic otitis media and mastoiditis, characterized by the presence of granulation tissue or cholesteatoma. The biochemistry, microbiology, and pathology as well as clinical features of the disease are discussed.
