  • Title: Normal gas exchange in the human middle ear.
    Author: Elner A.
    Journal: Ann Otol Rhinol Laryngol; 1976; 85(2 Suppl 25 Pt 2):161-4. PubMed ID: 1267341.
    Abstract:
    Different kinds of biological gas pockets and the special character of the middle ear as a gas pocket are discussed. The pattern of gas absorption from the normal middle ear and from ears with blocked Eustachian tubes is presented. The amount of gas leaving the ear by diffusion and the resulting underpressure from this process are determined. The composition of air in the ear is compared to that in experimental gas pockets and the role of the partial pressures of CO2 and O2 in secretory otitis media is discussed.
