Several preliminary reports have appeared in the medical literature in respect to eustachian tube substitution since Zollner first described his inability to open the obstructed eustachian tube. These procedures have the disadvantage that the distal end of the eustachian tube subsitute is inaccessible by other than another operation. This paper is follow-up report to our clinical experience. The purpose of the experiment was to determine whether the middle ear was ventilated by the tympano-oropharyngeal substitute eustachian tube and whether ascending infection occurred. Fourteen ears underwent eustachian tube substitution. The natrual eustachian tubes of these ears were obliterated three to five months after eustachian tube substitution had been performed. The animals were killed three to four months after obliteration of the natural eustachian tubes. Studies of the decalcified sections showed an absence of infection in six of the ears, with mild to severe inflammation in the rest of the specimens.
自从佐尔纳首次描述其无法打开阻塞的咽鼓管以来，医学文献中已经出现了几篇关于咽鼓管替代术的初步报告。这些手术的缺点是，除了再次手术外，无法触及咽鼓管替代物的远端。本文是我们临床经验的随访报告。该实验的目的是确定中耳是否通过鼓室-口咽替代咽鼓管进行通气，以及是否发生上行感染。十四只耳朵接受了咽鼓管替代术。在进行咽鼓管替代术后三至五个月，这些耳朵的自然咽鼓管被闭塞。在自然咽鼓管闭塞三至四个月后处死动物。对脱钙切片的研究显示，六只耳朵没有感染，其余标本有轻度至重度炎症。
