In this paper, homeostatic mechanics of the Eustachian tube and those of the gas exchange function through the ME mucosa were reviewed. Then the relationship between those functions and the morphological characteristics of the ME cavity were discussed. The gas exchange function through the ME mucosa, especially mucosa of the mastoid cavity was confirmed in normal ears, but the function was reduced in inflamed ears. The human ME cavity had a large surface area corresponding to a large volume due to the presence of the air cell system. The gas exchange function through the ME mucosa depended on the surface area. These suggested that the morphological characteristics of the ME cavity provides a great advantage in regulating the ME pressure by transmucosal gas exchange function.}, pages = {453--460}, title = {中耳腔の換気のメカニズムとその障害}, volume = {127}, year = {2013} }
