Valentin于1903年关于用内窥镜观察咽鼓管咽口的论文被认为是国际上最早的报告。此后Nitze利用具有透镜的早期膀胱镜观察咽鼓管咽口及其周围,并就所见各种类型作了描述。其后虽然发表了许多有关咽鼓管咽口的观察报告,但尚未见到关于咽鼓管内景的观察记录。本文介绍的是用纤维内窥镜观察咽鼓管内腔的方法及其结果。此法作为咽鼓管机能的检查法之一,与其他咽鼓管机能检查法互相弥补,具有重要意义。【原理】欲行咽鼓管观察者,必须对咽鼓管的整体结构及其病态有充分理解。咽鼓管的开放运动,首先是腭帆提肌运动使咽鼓管呈开放状态其次是腭帆张肌运动使咽鼓管软骨部开大而完成,并非像有人认为的那样——咽鼓管的开放运动与腭帆提肌和腭帆张肌无关。
Valentin in 1903 on the use of endoscopy to observe eustachian tube pharynx mouth paper is considered to be the first international report. Since then Nitze has used a lens with early cystoscopy to observe the eustachian tube pharynx and its surroundings and described various types of findings. Although later published a number of observations on the eustachian tube pharynx mouth observation, but has not yet seen the Eustachian tube inside the scene of the observation records. This article describes the use of fiber endoscopy Eustachian tube cavity method and the results. This method as one of the eustachian tube function test method, and other eustachian tube function test method complement each other, is of great significance. 【Principle】 For the eustachian tube observer, the overall structure of the eustachian tube and its pathology must be fully understood. Eustachian tube open movement, the first is the levator masturbation of the palatal sail open the eustachian tube is followed by the palatal fan Zhang Chang muscle motion to open large and complete eustachian tube cartilage, not as some people think - Eustachian tube The open movement has nothing to do with the palatal sapiens and the palatal fan.
