  1. 1. Middle ear structure in relation to function : the rat in middle ear research

    Författare :Nils Albiin; Umeå universitet; []
    Nyckelord :rats; Eustachian tube; ear; middle; tympanic membrane; palatal muscles; mucous membrane; blood vessels; mast cells; otitis media; microscopy; electron;

    Sammanfattning : The present study was undertaken to evaluate the rat as a model for middle ear re­search. The rat was chosen primarily because the gross structure of its middle ear shows several similarities to that of man. LÄS MER

  3. 2. Middle ear mechanics : using temporal bone experiments to improve clinical methods

    Sammanfattning : BackgroundThe middle ear transmits and amplifies sound vibrations from the tympanic membrane via three ossicles to the inner ear. Moreover, it contains two muscles, the stapedius muscle (SM) which protects the inner ear from loud noise, and the tensor tympani (TT) whose function is still debated. LÄS MER

  4. 3. Transmyringeal middle ear ventilation : an experimental approach to evaluation of its benefits and consequences

    Författare :Ove Söderberg; Sten Hellström; Lars-Eric Stenfors; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Middle ear; tympanic membrane; otitis media; heat myringotomy; laser myringotomy; tympanostomy tube; transmyringeal ventilation;

    Sammanfattning : A prerequisite for a functioning middle ear is an air-filled middle ear cavity. Aeration of the middle ear cavity is controlled by the Eustachian tube. Dysfunction of the Eustachian tube has long been acknowledged as a significant etiological factor in disorders of the middle ear, especially middle ear effusions. LÄS MER

  5. 4. Middle ear cholesteatoma : Surgical outcome and aspects of the innate immunity

    Författare :Johanna Westerberg; Elina Mäki-Torkko; Henrik Harder; Anna Granath; Juha Silvola; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Cholesteatomas are bone destructive expansions of keratinizing squamous epithelium in the middle ear and temporal bone. Today, surgery is the only treatment. There are several controversies regarding cholesteatomas, including the definition, the pathogenesis and the surgical method. LÄS MER

  7. 5. The middle ear : The inflammatory response in children with otitis media with effusion and the impact of atopy : clinical and histochemical studies

    Författare :David S. Hurst; Uppsala universitet; []
    Nyckelord :Medical sciences; Allergy; atopy; eosinophil cationic protein; IL-5; tryptase; otitis media with effusion; in vitro testing; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

    Sammanfattning : Otitis media with effusion (OME) is the major form of chronic relapsing inflammatory disease of the middle ear, constitutes the most common diagnosis for children under 15 years old and is the major cause of auditory dysfunction in pre-school children. OME is a disease more commonly found in allergic children. LÄS MER
