Study Of Resonance Erequency In Diagnosing Of Qtitis Media With Effusion In Cleft Palate

Objective This study examined differences between a group of otitis media with effusion in cleft palate (whose tympanogram type was not B type) and a group of normal hearing in children on three tympanometric parameters. And investigated the relationships of these parameters between the two groups. The parameters were resonant frequency of middle ear, static admittance and tympanometric peak pressure at standard 226Hz tympanometry. The goal of this study was to evaluate the resonant frequency for distinguishing normal middle ears from ears with otitis media with effusion (OME) in children and to confirm that whether resonant frequency was prior to standard 226 Hz tympanometry.Method This study was designed to collect a total one hundred and fifty ears. AII subjects followed a clinical protocol, which consisted of a otoscopic examination, and audiometric measurements. These included pure tone audiometry, conventional tympanometry, multitympanometry test. Eighty ears were divided into normal hearing group(pure tone threshold≤15dBHL,air-bone gap≤10dBHL). Seventy ears were...
