咽鼓管的动态解剖很复杂，直到目前人们主要通过研究撷骨一咽鼓管的在体标本来了解它的管腔和管旁结构。采用超细光导显微内窥镜经鼓膜、鼓室，进入咽鼓管观察正常咽鼓管瓣膜部分的开一闭机制和探讨不同原因所致咽鼓管机能障碍的可能发病机理。报道18例患者，其中外伤性鼓膜穿 The dynamic anatomy of the eustachian tube is complex, until now it has been widely understood that its main lumen and tube side structures have been studied mainly by studying the eustachian tube. Using ultrafine light guide microscopic endoscope through the tympanic membrane, tympanic cavity, enter the eustachian tube to observe the normal eustachian tube valve opening and closing mechanism and to explore the different causes of eustachian tube dysfunction may pathogenesis. Eighteen patients were reported, including traumatic tympanic membrane
