title: The role of high frequency tympanometry in newborn hearing screening programme.
abstract: OBJECTIVE
  The hearing assessment of the newborns ideally should detect both middle and inner ear functions. The aim of this study is to control the association between otoscopic evaluation, multifrequency tympanometry and TEOAE results.
  
  
  METHODS
  Fifty new-borns otherwise healthy were tested after the otolaryngological evaluation by 226 and 1000 Hz tympanometries and transient evoked otoacoustic emissions (TEOAE's). The study was performed in three steps and 17 babies that could not pass from the first step they were tested in the second step with the same tests (226 Hz and 1000 Hz tympanometry and TEOAE) The babies that could not pass from the second step were evaluated by multifrequency tympanometries, TEOAE and acoustic brainstem responses (ABR) at the third step.
  
  
  RESULTS
  The association between the results obtained from otoscopic evaluation, multifrequency tympanometry and TEOAE were assessed. We found that 1000 Hz tympanometry results were more sensitive and gives more correlated with TEOAE and otoscopic evaluation.
  
  
  CONCLUSIONS
  Multifrequency tympanometry can detect the middle ear pathologies of the infants sensitively and should be a part of neonatal hearing screening test battery.
