Rising Resonance Frequency Is the Sole Sign of Early Middle Ear Disease in Children With Adenoid Hypertrophy.
The present study seeks to estimate the potential of multifrequency tympanometry in the diagnosis of primal otologic disorder in children with adenoid hypertrophy (AH).Prospective observational study.Tertiary pediatric institution.One hundred thirty-one children presenting consecutively at the otolaryngology clinic were divided on the basis of AH into 98 patients and 33 controls.Middle ear status was assessed using pneumatic otoscopy, standard, and wide band tympanometry.Tympanogram type/intratympanic pressure, and resonance frequency (RF) were correlated with each other as well as with a set of clinical parameters. Receiver operating characteristic analysis was employed to reveal the diagnostic value of RF.Mean RF declined in chronic otitis media with effusion by 43.25% (p
