[Significance of tube manometry in the assessment of tube function. A comparison of tube manometry results and continuous direct determination of pressure in the middle ear].

Tube manometry--also known as aspiration-deflation-test--is an often used, practicable clinical test for tube function. By comparing tube manometric results with continual measurements of the middle ear pressure, a close correlation between both test results could be demonstrated. Tube manometric tests thus permit an estimation of the tube function as well as of the probable development of the middle ear pressure. An exact classification in terms of physiologic and pathologic tube function, however, is not possible. It is clear that even a partial equalization of low-pressure values in tube manometry should be interpreted as physiologic.
