Recent studies have shown that gas exchange via the middle ear mucosa, which is performed between the middle ear cleft and capillaries in the submucosal connective tissue, has an essential role in ventilation and pressure regulation in the middle ear cleft. We speculated that gas exchange via the mucosa is induced by the gas diffusion caused by the partial pressure gradient of gas between the middle ear cleft and submucosal capillaries.
