The local treatment of acute otitis media consists of an early paracentesis or in the care of the external auditory canal when suppuration occurs. Causal treatment requires a restoration of the nose, the paranasal sinuses, and the nasopharynx to normal function. For general treatment, chemo- or antibiotic therapy is most prominent. Such is not always necessary, but if it is required, it must be given in high doeses until all cardinal symptoms have disappeared. An insufficient treatment leads to a pathomorphosis which can be observed as mucoid or secretory otitis media in 4--8 year old children.
