The tympano-nasopharyngeal shunt operation is recommended as a "substitute" Eustachian tube. An experimental study regarding the efficacy of tympano-nasopharyngeal shunt operation was conducted in two dogs. Finally, four patients with complete tubal stenosis were operated on by this new method within a period of one year, with no postoperative complications. The hearing improved and patients were able to inflate their middle ears. The method is claimed to have the following advantages: permanent ventilation of the middle ear with preservation of an intact drum; the middle-ear pressure can be increased by Valsalva or Politzer manoeuvres; moderate technical difficulties; no risk of postoperative complications; and suitable in children as well as adults. The disadvantages seem to be: drainage not ensured; minor risk of ascending infection.
鼓室 - 鼻咽分流术被推荐作为咽鼓管的“替代物”。在两只狗身上进行了关于鼓室 - 鼻咽分流术疗效的实验研究。最终，在一年时间内，有四名完全性咽鼓管狭窄患者接受了这种新方法的手术，术后无并发症。听力得到改善，患者能够对中耳进行充气。该方法据称具有以下优点：中耳永久性通气且鼓膜保持完整；可通过瓦尔萨尔瓦动作或波利策尔手法增加中耳压力；技术难度适中；无术后并发症风险；适用于儿童和成人。其缺点似乎是：引流无法保证；有轻微的上行感染风险。
