Without change we know the typical manifestation of the purulent infection of the middle-ear with its complications. Certainly, however, opposite to these cardinal forms there are plenty of them with a mixed, falsified and levelled manifestation. Concerning the acute purulent otitis today Fleischer differentiates the "typical", the "light and abortive", the "latent" and the "protracted" form. Respecting the secretory otitis media however, there has been no change of shape - but only an evident increase of morbidity accounting to the acute purulent infection of the middle ear. Microscopical and electron microscopical as well as immunological researches have essentially cleared up the pathogeny of the secretory otitis media. The same is valid for the special form of the blue ear drum, the idiopathic hemotympanum.
