 If those patients with a B type tympanogram have a high rate of eventual antibiotic usage, delaying their treatment is not significantly reducing our overall antibiotic usage. Furthermore, the investigators could reduce the pain suffered by these patients in those first 48-72 hours. The corollary to this may be that those patients with other tympanogram patterns may have comparatively low need for antibiotics. This study would help to more accurately identify those patients likely to derive significant benefit from antibiotic treatment for AOM.
