[Direct continuous measurement of middle ear pressure: method and clinical results (author's transl)]. 1979

U Koch, and F Middendorf

Method (part 1): A method for the direct measurement of the middle ear pressure for clinical use is introduced. This method allows continuous pressure registration in the normal and pathological middle ear. The determination of the parameters influencing middle ear pressure like volume of the middle ear cavity, gas resorption, tube function is possible. The influence of body movement, changes of temperature etc. on the middle ear pressure can be registrated. The precondition for this method is a tube in the tympanic membrane. Clinical results (part 2): In 42 patients pressure development in physiological tube function and dysfunction, in patulous Eustachian tubes and tube obstructions can be registrated. The volume of the middle ear cavities and the increasing negative pressure because of gas resorption can be analysed with this method. In obstructed tubes different development of negative pressure may indicate differences in the elasticity of tympanic membranes. This method gives valuable criterion on middle ear pressure changes considering parameters like gas diffusion, tube function, cavity volume and membrane elasticity in normal and pathological middle ears.

UI MeSH Term Description Entries
D008365 Manometry Measurement of the pressure or tension of liquids or gases with a manometer. Tonometry,Manometries
D009068 Movement The act, process, or result of passing from one place or position to another. It differs from LOCOMOTION in that locomotion is restricted to the passing of the whole body from one place to another, while movement encompasses both locomotion but also a change of the position of the whole body or any of its parts. Movement may be used with reference to humans, vertebrate and invertebrate animals, and microorganisms. Differentiate also from MOTOR ACTIVITY, movement associated with behavior. Movements
D011312 Pressure A type of stress exerted uniformly in all directions. Its measure is the force exerted per unit area. (McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed) Pressures
D002404 Catheterization Use or insertion of a tubular device into a duct, blood vessel, hollow organ, or body cavity for injecting or withdrawing fluids for diagnostic or therapeutic purposes. It differs from INTUBATION in that the tube here is used to restore or maintain patency in obstructions. Cannulation,Cannulations,Catheterizations
D004432 Ear, Middle The space and structures directly internal to the TYMPANIC MEMBRANE and external to the inner ear (LABYRINTH). Its major components include the AUDITORY OSSICLES and the EUSTACHIAN TUBE that connects the cavity of middle ear (tympanic cavity) to the upper part of the throat.

D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D013696 Temperature The property of objects that determines the direction of heat flow when they are placed in direct thermal contact. The temperature is the energy of microscopic motions (vibrational and translational) of the particles of atoms. Temperatures
D014432 Tympanic Membrane An oval semitransparent membrane separating the external EAR CANAL from the tympanic cavity (EAR, MIDDLE). It contains three layers: the skin of the external ear canal; the core of radially and circularly arranged collagen fibers; and the MUCOSA of the middle ear.
