the principal muscle to open the eustachian tube and the cause of the incidence of otitis media changing with age was analysed.

分析了对咽鼓管开放起主要作用肌肉的功能和中耳炎发病率因年龄而变化的原因。

levator veli palatini muscle and infeior wall of eustachian tube move from the axis of the tube to outward gradually as increasing with age and overlapping proportion of them was reported.

对不同年龄的腭帆提肌与咽鼓管重叠的比例作了报道，提出了咽鼓管下壁和腭帆提肌随年龄增长而渐离管腔纵轴的观点；

conclusions when environmental pressure was added, positive pressure breathing higher than the ventilative resistance of the eustachian tube could prevent ear barotraumas.

结论当人体的环境压力增加时，经面罩提供大于咽鼓管通气阻力的正压呼吸可以预防耳气压伤的发生。
