Abstract
A review of medical records of unselected children in whom the otoscopic diagnosis of middle ear effusion was uncertain, showed that tympanometry resolved the diagnostic uncertainity with an accuracy of 88% for the prediction of a dry middle ear and an accuracy of 85% for predicting fluid in the middle ear. Tympanometry itself gave inconclusive findings in 11% of cases. Tympanometry can greatly reduce the need for diagnostic aspiration of the middle ear.
