title: [Confirmation of patulous eustachian tube syndrome by Tubo-tymanoaerodynamic graphy].
abstract: OBJECTIVE
  To compare the advantage of tympanogram, Morimitsu's method and Tubotymanoaerodynamic graphy (TTAG) in the confirmation of patulous eustachian tube syndrome.
  
  
  METHODS
  Twenty ears with patulous eustachian tube syndrome diagnosed clinically were selected. The tympanogram, Morimitsu's method and TTAG were examined in these ears and the positive rate was estimated.
  
  
  RESULTS
  The confirmation of patulous eustachian tube syndrome by tympanogram, Morimitsu's method and TTAG was 5, 12 and 20 ears in 20 ears with patulous eustachian tube syndrome. The positive rate was 25%, 60% and 100% respectively. TTAG also was useful in following-up.
  
  
  CONCLUSIONS
  TTAG is an important method for diagnosis and following-up in patulous eustachian tube syndrome.
