title: [226 Hz and high frequency tympanometry in children with cleft lip and/or palate].
abstract: In this paper authors performed multifrequency tympanometry in the material of 85 cleft palate children. The results of tympanometry 226 Hz, as a base were estimated as follows: the normal type A tympanogram in 64.1%, type C1 in 11.8%, C2 in 8.8% and type B in 15.3% of the ears. Irregular tympanograms 678 Hz discordantly with Vanhuyse model were estimated in 21.5% of the ears. Resonance frequency at the normal range value was appeared in 114 ears (79.2%), increased over 1243 Hz in 18 ears (12.5%) and was lower then 565 Hz in 12 (8.3%) ears. Abnormal tympanometric results using multifrequency examination were obtained in 28.4% of the ears which had previously in tympanometry 226 Hz type Apattern.
