The author designed an apparatus for acoustical douche of the Eustachian tube basing the idea of Perlmans pneumophone and fount it was more preferable clinically than the catheterization commonly used. It consists of an audiometer, an amplifier, a horn speaker unit, a manometer aglass bottle for stability of air pressure and a rubber balloon as an air compresser. Acoustical douche by the authors apparatus requires air pressure of 0_??_30mmH2O for the normal patent Eustachian tube while the catheterization requires air pressure of 20 to 60mmHg. Such a large difference in air pressure between the two methods is considered to be due to the opening function of the tube during swallowing because the former method is performed during the swallowing. The authors method will be further studied by the application to many patients with oto-rhinological diseases.
