  • Abstract
  • Look Inside

 Evaluation of 3 different methods of impedance tests for tubal function was carried out.

 1) Diagnosis by single tympanometry was found to be unreliable, because the obstructive tube produced any type of tympanogram.

 2) Tympanometry before and after tubal inflation by Valsalva's maneuver indicated the dynamic process of tubal opening. However, the disadvantage is that the measurement of tubal obstruction in a patient showing type B tympanogram was difficult to perform.

 3) By impedance measurement during tubal inflation, the diagnosis of tubal dysfunction was made by a rather simple pattern of compliance. Its disadvantage would be difficulty of quantitative judgement of tubal function.
