  1. 1. Middle Ear Cholesteatoma : Surgical Treatment, Follow-up and Hearing Restoration

    Författare :Lennart Edfeldt; Helge Rask-Andersen; Juha Silvola; Uppsala universitet; []
    Nyckelord :Oto-Rhino-Laryngology; Oto-rhino-laryngologi;

    Sammanfattning : Although middle-ear cholesteatoma is a major topic in otological research, its etiology and pathogenesis remain unclear. Pediatric cholesteatoma is considered more aggressive than adult cholesteatoma, as it has a higher rate of growth, is more often infected and exhibits wider extension. LÄS MER

  3. 2. 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

  4. 3. On Pressure Regulation of the Middle Ear

    Författare :Marianne Brattmo; allergi och livskvalitet Laryngoesofagologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chronic otitis media; Sniffing behaviour; Tubal opening; gas diffusion; Meniere s disease; Attic cholesteatoma; Chronic central perforation; Tympanic membrane; Continuous measurement; Middle ear pressure; Eustachian tube;

    Sammanfattning : The middle ear (ME) pressure is regulated by gas diffusion over the ME mucosa and pressure equalizations via the Eustachian tube (ET). Disturbance in the regulation of ME pressure is believed to contribute to the development of chronic ear diseases. LÄS MER

  5. 4. 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

  7. 5. 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
