That condition where the tympanic membrane is displaced toward the promontory is termed atelectasis. Thirty-seven patients (61 ears) showing various degrees of atelectasis graded from stage 1 to stage 4 were studied. Atelectatic drums are an inflammatory phenomenon occurring in underventilated ears. This conclusion is reached by considering the reversibility of the atelectasis upon ventilation; while the inflammatory factor can be deduced from the history and histopathology of the atelectatic drum, as well as the histology of the necrosed incus, the latter occurs in over a third of our cases. Also pneumatization of the mastoid is almost never present. Twelve (21%) of the ears treated did indeed develop a perforation at one time or another (two had cholesteatomas). Chronic granulating external otitis with specific features occurred in 15% of cases. The characteristics of these ears and their case histories lead us to view atelectatic ears as part of the otitis media syndrome, where their place is somehow transitional between secretory otitis media on the one hand and chronic otitis media on the other.
