Tympanometric findings in young infants with middle ear effusion: some further observations.
This study sought to investigate further the role of tympanometry in detecting otitis media with effusion (OME) in infants 5 months of age and below. Tympanometric data were obtained from 26 infants (40 ears) with pneumo-otoscopic diagnosis of OME. Results demonstrated normal tympanograms for 8 (20%) of the 40 ears despite the presence of effusion. Results are discussed relative to the possible explanation for normal tympanograms with fluid present in young infants.
