  1. 1. Morphology and biochemistry of the tympanic membrane in relation to retraction pathology

    Författare :Johan Knutsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Tympanic membrane; retraction pathology; secretory otitis media; cholesteatoma; pars tensa; lamina propria; keratinizing epithelium; collagen type; progenitor cells; stem cells; immunohistochemistry; electron microscopy;

    Sammanfattning : Otitis media is very common during childhood and may predispose for tympanic membrane (TM) pathology later in life. Therefore, it is important to investigate the possible changes in TMs subjected to otitis media. There is evidence of a relationship between previous otitis media and TM retraction disease. LÄS MER

  3. 2. Stiffness changes of the tympanic membrane in otitis media

    Författare :Christina Larsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Tympanic membrane; pars flaccida; stiffness; otitis media with effusion; purulent otitis media; cholesteatoma; moire interferometry; tympanometry; gerbil.;

    Sammanfattning : Acute purulent otitis media and otitis media with effusion, are common diseases in childhood. Years later some of the children will get "complications", such as retraction pockets and cholesteatoma, that often need advanced surgical treatment. LÄS MER

  4. 3. 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

  5. 4. Developing otitis media : experimental studies in particular regarding inflammatory changes in the tympanic membrane

    Författare :Per Olof Eriksson; Sten Hellström; Karin Prellner; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Otorhinolaryngology; otitis media with effusion; acute otitis media; myringotomy; tympanic membrane; rat; Streptococcus pneumoniae; compound 48 80; mast cell; Otorhinolaryngologi; Otorhinolaryngology; Otorhinolaryngologi; Oto-Rhino-Laryngology; oto-rhino-laryngologi;

    Sammanfattning : Otitis media (OM), one of the commonest of childhood diseases, causes much suffering. OM exists in a variety of forms, two of which are acute otitis media (AOM) and otitis media with effusion (OME). LÄS MER
