title: [Audiological and Otological Status of 45 Infants with Cleft Palate].
abstract: OBJECTIVE
  To study the audiological and otological status of cleft palate infants with the application of distortion product otoacoustic emission (DPOAE), auditory brainstem response (ABR), tympanometry with 1000 Hz and 226 Hz probe tones.
  
  
  METHODS
  Totally 45 cleft palate infants aged 8-24 months were included in the study. Most of them were examined for DPOAE, ABR and two frequency tympanometry.
  
  
  RESULTS
  Most infants failed the three tests,among whom 6.7% ears passed DPOAE and 33.3% of ears had normal ABR hearing threshold. In addition, 8.9% of ears turned out normal in the 1000 Hz probe-tone tympanometry, and 13.3% were type A in the 226 Hz probe-tone tympanometry. Finally, 1000 Hz tympanometry had more agreement with DPOAE and latency of ABR wave I than 226 Hz tympanometry.
  
  
  CONCLUSIONS
  Most cleft palate infants have audiological and otological problems, which should be evaluated in a more comprehensive manner.
