A Study on Systematic Clinical Functional Test of the Eustachian Tube and Its Applications (No.2)

输卵管功能障碍是中耳炎发病及影响其预后的重要因素。因此，输卵管功能障碍的诊断和治疗是该领域研究的主要目标。本研究旨在探索一种可用于临床的输卵管功能障碍的系统检测方法。咽鼓管在吞咽时通常表现为主动开放，以实现中耳腔的通气、气压平衡和引流。为检验该管的这些功能成就，得出以下结论：（1）管声测试法将为吞咽动作主动开口的检测提供一种简便易行的方法。（2）测压试验将定量地揭示管道作为一个整体结构的压差释放功能的紊乱.为了制定输卵管功能障碍的治疗方案，分析功能障碍的部位及其治疗方法是不可缺少的。 ...更多信息 机制（3）内窥镜检查是明确功能障碍部位和机制的最佳方法。咽鼓管内窥镜检查的主要方法有：（1）咽鼓管咽口及相关结构，即咽鼓管圆枕、腭帆、肥大腺样体和咽鼓管圆枕，以及它们的形态和功能。（B）用有通道的纤维内窥镜观察管的软骨部分。充气状态下的行为将是诊断的重要信息，特别是在具有顺应性管的情况下。（c）通过引入直径为0.65mm的超薄光纤检查管的骨质部分。这将揭示狭窄的输卵管峡部，最难检测的网站，和骨质部分。(d)In为了研究管道各部位的压力释放机理，介绍了一种超薄型压力传感器，并对其应用进行了研究.应用该方法，对儿童中耳乳突瘤和上腭畸形的输卵管功能障碍进行了临床研究，发现潜伏性顺应性输卵管的存在率很高。少

Tubal dysfunction is an important factor which plays a prominent role to originate otitis media and influence its prognosis. Therefore, main targets of research in this field are directed toward diagnosis and treatment of various kinds of tubal dysfunction.In this research project, a systematic method of testing tubal dysfunction utilizable on clinical basis is investigated.1. The eustachian tube normally behaves active opening on swallowing to achieve ventilation, air pressure balance and drainage of the middle ear cavity. To test these functional achievement of the tube, the following conclusions were made: (1)Tubo-acoustic testing method will extend an appropriate and easy method of checking active opening on swallowing action. (2)Manometric tests will reveal disorders of release function of pressure difference of the tube quantitatively as a whole structure.2. In order to plan the treatment of tubal dysfunction, it is indispensable to analyze the site of functional disorder and its … More mechanism. (3)Endoscopic examination will be most appropriate to clarify the site of dysfunction and its mechanism. State-of-the-art methods of the eustachian tube endoscopy are summarized as follows: (a)The pharyngeal tubal orifice and related structures, that is, the tubal torus, palatal velum, hypertrophied adenoid and tubal torus, and their behaviors are observed with usual flexible fiberscopes. (b)The cartilaginous portion of the tube is observed with a channeled fiberscope. The behaviors under air inflation will be an important information for diagnosis, especially in cases with compliant tube. (c)The osseous portion of the tube is checked with the introduction of the ultra-thin fiberoptics of 0.65mm in diameter. This will reveal the stenosis at the tubal isthmus, the most difficult-to -detect site, and the osseous portion. (d)In order to investigate pressure release mechanism of each site of the tube, an ultra-thin pressure transducer is introduced and its utilization is investigated.3. With this procedures, tubal dysfunction in cases with pediatric cholesteatoma and maxillo-palatal abnormalities were investigated clinically, and a high rate existence of latent compliant tube is revealed.
