• Impedance tympanometry was performed on children with acute otitis media. Most acute tympanograms were classified as either type B (no peak pressure) or positive-pressure tympanograms. A striking difference in outcome was noted between these two groups: the patients with positive-pressure tympanograms were more likely to have normal results with examination at the two-week follow-up than were those with type B tympanograms. There was no difference in outcome between antihistamine-decongestant and placebo regimens evaluated concurrently.
