[1979年7月在伯明翰举行了英国第五届耳鼻咽喉科学术会议。参加会议的除英国本国学者外,还有美、澳和北欧诸国的耳鼻咽喉科专家。J Laryngol Otol 94(1),1980为有关此次会议活动情况和论著的专集。本文为其中关于“慢性咽鼓管功能障碍”一组论文的综合报道。] 中耳粘膜的组织病理学研究多年来一直认为中耳粘膜相当于正常呼吸道较低级的粘膜类型。固有鼓室的上皮呈扁平骰状,由1到3层无纤毛的细胞组成。咽鼓管口的正常中耳粘膜则由纤毛柱状上皮细胞构成,向后延伸,主要是通过下鼓室区,大约覆盖着鼓室粘膜的1/3。咽鼓管功能障碍引起慢性渗出时,鼓室粘膜的病理改变可从单纯的粘膜增生到具有很多分泌上皮细胞和上皮下腺体的高度增厚的粘 [The Fifth British Otolaryngology Conference was held in Birmingham in July 1979. In addition to the British national scholars attending the meeting, as well as the United States, Australia and the Nordic countries otolaryngology experts. J Laryngol Otol 94 (1), 1980 is a collection of activities and treatises on the conference. This article is a comprehensive presentation of a series of papers on “chronic eustachian tube dysfunction.” Histopathology of the middle ear mucosa has been considered for many years as the lower ear mucosa of the normal respiratory tract. The tympanic epithelium is flattened dice, composed of 1 to 3 layers of cilia-free cells. Eustachian tube orifice of the normal middle ear mucosa by the ciliated columnar epithelial cells, extending backward, mainly through the lower tympanic area, covering about 1/3 of the tympanic mucosa. Eustachian tube dysfunction caused by chronic exudation, the pathological changes of the tympanic mucosa proliferation can be simply from the mucosa to have a lot of secretion of epithelial cells and subepithelial gland thickening of the thick
