Method (part 1): A method for the direct measurement of the middle ear pressure for clinical use is introduced. This method allows continuous pressure registration in the normal and pathological middle ear. The determination of the parameters influencing middle ear pressure like volume of the middle ear cavity, gas resorption, tube function is possible. The influence of body movement, changes of temperature etc. on the middle ear pressure can be registrated. The precondition for this method is a tube in the tympanic membrane. Clinical results (part 2): In 42 patients pressure development in physiological tube function and dysfunction, in patulous Eustachian tubes and tube obstructions can be registrated. The volume of the middle ear cavities and the increasing negative pressure because of gas resorption can be analysed with this method. In obstructed tubes different development of negative pressure may indicate differences in the elasticity of tympanic membranes. This method gives valuable criterion on middle ear pressure changes considering parameters like gas diffusion, tube function, cavity volume and membrane elasticity in normal and pathological middle ears.
方法（第1部分）：介绍了一种用于临床直接测量中耳压力的方法。该方法可在正常和病理性中耳中进行连续压力记录。能够确定影响中耳压力的参数，如中耳腔体积、气体吸收、咽鼓管功能等。还可记录身体运动、温度变化等对中耳压力的影响。此方法的前提是鼓膜中有一根导管。临床结果（第2部分）：在42例患者中，可记录生理咽鼓管功能和功能障碍、咽鼓管异常开放和咽鼓管阻塞时的压力变化。用该方法可分析中耳腔的体积以及因气体吸收导致的负压增加。在阻塞的咽鼓管中，负压的不同发展可能表明鼓膜弹性的差异。该方法为正常和病理性中耳中考虑气体扩散、咽鼓管功能、腔体积和鼓膜弹性等参数的中耳压力变化提供了有价值的标准。
