  2. 1. Developing otitis media : experimental studies in particular regarding inflammatory changes in the tympanic membrane

    Author : Per Olof Eriksson; Sten Hellström; Karin Prellner; Umeå universitet; []
    Keywords : 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;

    Abstract : 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). READ MORE

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

    Author : Ove Söderberg; Sten Hellström; Lars-Eric Stenfors; Umeå universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 3. Healing of tympanic membrane perforations : an experimental study

    Author : Anisur Rahman; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Embryonic stem cells; Healing; Immunosuppressive; Laser; Mesenchymal stem cells; Moiré interferometry; Myringotomy; Perforation; Tympanic membrane;

    Abstract : Most acute tympanic membrane perforations heal spontaneously without any residual complication, whereas a fraction transforms into a chronic perforation. The current treatment of a chronic perforation is surgical repair, which is a costly, time consuming and uncomfortable procedure particularly for the pediatric patients. READ MORE

  6. 4. The effects of plasminogen deficiency on the healing of tympanic membrane perforations

    Author : Annika Hansson; Sten Hellström; Diana Berggren; Tor Ny; Magnus von Unge; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tympanic membrane; macrophages; neutrophils; fibrin ogen ; inflammation; keratinocyte migration; wound healing; uPA; tPA; in vitro; Otorhinolaryngology; Otorhinolaryngologi;

    Abstract : The healing of tympanic membrane (TM) perforations is a complex wound healing process including inflammation, migration of keratinocytes and tissue remodelling. Most TM perforations in human heal spontaneously, however some perforations become chronic, and the reason to why is still largely unknown. READ MORE

  7. 5. Topical anesthesia of the tympanic membrane : an experimental animal study

    Author : Sten-Hermann Schmidt; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Topical anesthesia; middle ear; tympanic membrane; cochlea; collagen fibres; lidocaine; 96 % phenol; Bonain s liquid; auditory brainstem response; ototoxicity; cytocochleogram; scanning electron microscopy; rat; guinea pig;

    Abstract : Myringotomy plays an important role in otological therapy. The procedure requires an efficient anesthesia, which can be obtained without general anesthesia. However, the use of local anesthetics on the tympanic membrane (TM) has been abandoned in many places, as general anesthesia has been readily available. READ MORE
