中耳气压性损伤是空军和潜艇部队人员较常见的疾患,也是引起飞机乘客不适的主要原因。当大气压力变化时,由于咽鼓管不能及时开放,造成鼓室内外压力差大,就会引起中耳气压性损伤。随着人耳咽鼓管存在表面活性物质的提出和证实,目前越来越多的研究者认为中耳气压性损伤同咽鼓管表面活性物质有着密切的关系。 Bariatric pressure injury in the middle ear is a more common cause of air force and submarine force personnel and is also a major cause of discomfort to aircraft passengers. When the atmospheric pressure changes, due to the eustachian tube can not be opened in time, causing the tympanic pressure difference between the inside and outside, it will cause pressure injury in the middle ear. With the existence and confirmation of surfactant in the human ear and eustachian tube, more and more researchers think that there is a close relationship between the barotrauma of the middle ear and the surface active substances of the eustachian tube.
