title: Tympanometric assessment of eustachian tube patency in children.
abstract: Eustachian tube patency was assessed tympanometrically in a group of otologically normal children at a pediatric outpatient clinic. A pressure-swallow technique of assessing eustachian tube patency was administered. The results indicated the importance of the examination of both middle ear pressure and function changes in the evaluation of eustachian tube test results.
