目的/假设：通过经咽鼓管内窥镜评估咽鼓管地位的研究较少，需要对咽鼓管在慢性耳部疾病中的作用进行更充分的研究，特别是因为咽鼓管与慢性耳部疾病的慢性和发病机制有关。因此，本研究的目的是根据经咽鼓管内窥镜的观察结果来评估咽鼓管。研究设计：22名患有慢性耳部疾病的成年患者知情同意参加一项前瞻性的经咽鼓管内窥镜调查。方法：采用柔性、纤维、无关节（外径0.5 mm）和关节（外径1.0 mm）内窥镜（相干融合束3000像素），咽鼓管内窥镜在全身气管麻醉下进行，作为慢性耳科疾病更大的耳科手术的第一部分。结果：0.5 mm内窥镜从中耳（经鼓室入路）完全通过咽鼓管进入咽口，占16%。狭窄性阻塞发生在37%的漏斗，42%的峡部和5%的罗森穆勒窝。在64%的病例中，耳咽管粘膜异常。长期患病（大于或等于20岁）的人发生耳咽管粘膜异常的风险是无长期患病(
Objectives/Hypothesis: A paucity of research exists on trans-eustachian tube endoscopy to evaluate the status of the eustachian tube, Fuller examination of the role of the eustachian tube in chronic ear disease is needed, particularly because the eustachian tube has been implicated in the chronicity and pathogenesis of chronic ear disease. Therefore the purpose of this study was to evaluate the eustachian tube, based on observations from trans-eustachian tube endoscopy, Study Design: Twenty-two adult patients with chronic ear disease gave informed consent to participate in a prospective, trans-eustachian tube endoscopic investigation. Methods: Flexible, fiberoptic, nonarticulating (outside diameter of 0.5 mm) and articulating (outside diameter of 1.0 mm) endoscopes (coherent fused bundle of 3,000 pixels) were employed, The eustachian tube endoscopy was performed under general endotracheal anesthesia as the initial part of a larger, otological surgical procedure for chronic ear disease. The endoscope was passed from the middle ear (transtympanic approach) to the nasopharynx, Results: The 0.5-mm endoscope passed entirely through the eustachian tube from the tympanic orifice into the pharyngeal orifice in 16% of the cases. Stenotic blockage occurred at the infundibulum in 37% isthmus in 42% and fossa of Rosenmuller in 5% of cases. The eustachian tube mucosa was abnormal in 64% of cases, The risk for abnormal eustachian tube mucosa was four times greater for persons with long-standing disease (greater than or equal to 20 y) than for persons without long-standing disease (
