Atelectasis or adhesive otitis media is a potential sequela of otitis media with effusion. We investigated the relationship between the abnormal pars tensa retraction and predispositional fragility of the tympanic membrane against extrinsic force.The subjects were 11 patients with unilateral atelectatic ear. An attempt was made to estimate the original sti ength of the affected eardrum by comparing peak values of tympanograms from the non-pathological side of unilateral atelectatic ear with those from 100 normal controls.The mean static compliance of the eardrum was 1.55ml (SD=0.66) for the nonpathological side of unilateral atelectatic ears and 0.63ml (SD=0.16) for the normal controls. The atelectatic ear group showed a significantly higher static compliance of the eardrum.This finding suggests that some cases of the adhesive otitis media had a fragile eardrum with high compliance as a predisposition.
