Ørebetennelser hos barn – "alle har noen, men gutter har flest"
Mellomørebetennelse, eller otitis media, er en infeksjons- eller inflammasjonsprosess i mellomøret som
også rammer de tilgrensende avsnitt av denne delen av øvre luftveier, dvs. tuba auditiva og mastoidcellene,
selv om disse sjelden gir manifeste symptomer. OM er nesten alltid sekundært til en oppadstigende
slimhinnepatologi i nesen, epipharynx og tuba auditiva.
Otitis media in children. Nor J Epidemiol 1999; 9 (2): 123-127.
Otitis media refers to an infection or inflammation of the middle ear cavity that also affects the eustachian
tube and the mastoid cells. Otitis media is almost always caused by an ascending pathology of the
epithelial and subepithelial layers of the middle ear mucoperiostium. This paper firstly describes the
classification and distribution of otitis media. Next, using Norwegian data, host related risk factors for
otitis media are discussed, particularly focusing on gender differences.
