咽鼓管的

Objective To investigate the diagnostic value of tubo-tempanography by CT in obstruction of eustachian tube.

目的 探讨咽鼓管造影CT扫描对咽鼓管阻塞的诊断意义。

Eustachian tube inspection is also indispensable step.

咽鼓管的检查也是不可缺少的一步。

The patency of the eustachian tube is compromised.

咽鼓管的通畅被损害。

Therefore, the research on Eustachian tubes Function Instrument can push the study on Eustachian tube.

但目前尚未有采用计算机运作的实用检测仪器可供临床使用，所以咽鼓管功能测定仪的研制开发，将会进一步推动国内医疗单位对咽鼓管功能研究的发展。

The positive pressure of 6kPa was given via mask to the nasopharynx of the testee, while the control took normal breath.

被试者经面罩给予6kPa的鼻咽部正压，对照者正常呼吸，高压舱以0.5kPa／s的速率增压至5kPa，被试者和对照者均不采用其他任何主动或被动开放咽鼓管的措施，测鼓室腔压力；高压舱以同样速率增压至20kPa，被试者条件不变，对照者可进行主动或被动开放咽鼓管的措施，测鼓室压。

The abnormality of surfactant of Eustachian tube is an important cause resulting in functional disorder of Eustachian tube. Ectogenic surfactant is effective for the treatment of SOM.

咽鼓管内表面活性物质的异常是引起咽鼓管功能障碍的重要原因之一，外源性表面活性物质对分泌性中耳炎有一定疗效。

Results MRI findings of nasopharyngeal carcinoma appeared as diffusely or locally thickened nasopharyngeal walls,and pharyngeal recess was closed and pharyngeal opening of auditory tube became shallow or disappeared,sometimes with parapharyngeal space、retropharyngeal space and logus capitis oppressed or invaded.

结果：鼻咽癌的MRI表现为鼻咽壁局限性或弥漫性增厚，咽隐窝闭塞，咽鼓管咽口变浅或消失，可伴有咽旁间隙、咽后间隙、头长肌受压或浸润及颈部淋巴结的转移，可见乳突积液，颅底骨质破坏。

Abstract］ Objective To evaluate the effect of salpingocatheterism through pharyngeal opening of auditory tube under nasal endoscope and Ⅱ tympanoplasty.

摘要］ 目的探讨鼻内镜在视频系统下行咽鼓管咽口置管及鼓室成形Ⅱ型手术的效果。

Salpingocatheterism under nasal endoscope provides enlarged operation field and operation angle,flexible operation,accurate location.

鼻内镜在视频系统下咽鼓管置管具有独特的优势，视野阔、视角大、操作灵活、部位准确，扩大了鼓室成形术的适应证。

Cases were cuted by Nd:YAG laser called laser group, while the insertion group of 28 cases and the control group of 30 ones were each treated by different methods that eustachian tube insertion under nasal endoscope and eustachian tube blowing, and the effect of the three was evaluated.

其中26例施行Nd：YAG激光鼓膜造孔术治疗，为激光组；28例施行鼻内镜下咽鼓管置管术治疗，为置管组；30例施行传统的咽鼓管吹张术治疗，为对照组。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
