不同体位对咽鼓管功能影响的研究不多。文献中谓当头向前屈或平卧位时,鼻咽部需要有较高的压力才能使咽鼓管开放,是因在此体位时,围绕管口粘膜的静脉流体压力增高,淋巴郁积,使咽鼓管的通畅度减低。作者用声管测量法,测试正常人及感冒患者体位改变与咽鼓管功能的关系,并观察体位改变到什么程度才能影响它的功能。测试对象包括34名健康人,男性25,女性9,平均年龄35岁(21～56岁),2名咽鼓管功能正常的感冒患者。声管测量依次用6、7和8kHz音,被测试者取头直位,先饮水一次,然后吞咽唾液,每个测试音反复作同样动作三次,以测定咽鼓管的通畅性。34例中选择61耳咽鼓管通畅者作为观察对象。每个被测试者取4个体位:(1)坐式头直位;(2)仰卧头抬高20°;(3)仰卧头平位;(4)俯卧头平位。每个被测试者在4种不同的体位上,反复测试3次,为了避免观察的相互依赖性,34例测试对象都随机抽查一耳,将测量值作统计学处理(秩积检验法)未发现体位对咽鼓管功能有影响。但存在个体差异性,如有些人在卧位时反较坐位更易使咽鼓管开放,只有2例在俯卧位时不能使咽鼓管张开,但在其他体位均能使管张开;2例鼻咽炎患者,各种体位均能使咽鼓管开放。声管测量法是一种生理性试验,当吞咽使咽鼓管张开时,它能绘出一个可以信赖的图形,而且当鼻咽炎在发生或消退时,能灵敏地测出其改变。本研究结果说明,体位对咽鼓管功能的影响不像以往想像的那样重要,也不支持从前的那种看法,认为卧位时应将头抬高20°,可以防止发生中耳炎或促进中耳炎症的吸收。
There are not many studies on the eustachian tube function in different positions. Literature that when the head forward flexion or supine position, nasopharyngeal need to have a higher pressure to make the Eustachian tube open, because in this position, around the mucosa of the vein fluid pressure, lymphatic stasis so that Eustachian tube patency decreased. The author uses the sound tube measurement method to test the relationship between the position change of a normal person and a cold patient and the function of the eustachian tube and to observe the extent to which the body position changes to affect its function. Subjects included 34 healthy subjects, 25 males and 9 females, with an average age of 35 years (21 to 56 years) and 2 normal eustachian tube patients. Acoustic tube measurements followed by 6,7 and 8kHz tone, the subjects take the first straight position, first drink water, and then swallowing saliva, each test tone repeated the same action three times to determine the eustachian tube patency. Among the 34 cases, 61 eustachian tubes were selected as observation subjects. Each subject was taken four positions: (1) sit straight head position; (2) supine head elevation 20 °; (3) supine head level; (4) prone position level. Each subject was repeatedly tested 3 times in 4 different positions. In order to avoid the interdependence of observation, 34 subjects were randomized to one ear and the measured values were statistically processed (rank test) Found that position on the Eustachian tube function. However, there are individual differences. For example, some people are more likely to open the eustachian tube when sitting in the lying position. Only two patients can not open the eustachian tube when in the prone position, but they can open the tube in other positions. Cases of nasopharyngitis patients, a variety of positions can make Eustachian tube open. Acoustic tube testing is a physiological test that draws a reliable pattern when swallowed to open the Eustachian tube and can be sensitively measured as nasopharyngitis occurs or dissipates. The results of this study indicate that the effect of body position on Eustachian tube function is less important than previously thought and does not support the previous belief that head elevation should be 20 ° to prevent otitis or promote otitis media Absorption.
