A method was developed to observe tubal orifice movement by fiberscope and detect patency of the eustachian tube by a photoelectric device (phototubometry). A highly sensitive photodiode in the external ear canal detected tube opening as increased luminosity in the tympanic cavity from a light source placed at the pharyngeal portion of the eustachian tube. The phototubometric record was superimposed on a TV screen to compare the opening in the pharyngeal portion of the eustachian tube to the tube opening during swallowing. The phototubometric records of 21 normal subjects examined by phototubometry showed the close relationship with the opened tubal lumen at the tensor veli palatini muscle (TVP) attached portion. This method is useful for examining tubal patency and observing changes in the pharyngeal portion of the eustachian tube.
开发了一种通过纤维镜观察输卵管口运动并通过光电装置（咽鼓管测光度法）检测咽鼓管通畅性的方法。外耳道中的高灵敏度光电二极管检测到，由于放置在咽鼓管咽部的光源使鼓室亮度增加，从而检测到咽鼓管开口。咽鼓管测光度记录叠加在电视屏幕上，以比较吞咽时咽鼓管咽部开口与咽鼓管开口情况。对21名接受咽鼓管测光度检查的正常受试者的咽鼓管测光度记录显示，其与腭帆张肌（TVP）附着部分咽鼓管开放腔密切相关。该方法有助于检查咽鼓管通畅性并观察咽鼓管咽部的变化。
