Pathogenesis of Otitis Media

Abstract: Pathogenesis of otitis media was studied in humans and various animal models primarily from a pathological and chemical point of view. Findings were correlated and interpreted for various forms of otitis media in longitudinal and parallel studies, including acute purulent otitis media (POM), serous otitis media (SOM), mucoid or secretory otitis media (MOM), and chronic suppurative otitis media (COM), especially as regards the continuum or interrelated changes of various groups. Purulent otitis media was produc… Show more

“…1 OME often is considered a direct extension of the inflammatory process that occurs during long-lasting or recurrent episodes of acute otitis media (AOM), which is confirmed by the fact that almost all cases of OME follow episodes of AOM , and also corroborated by experimental animal studies. 2,3 The observations above suggest that OME has an infectious etiology. On the other hand, the cultures of middle ear aspirates are positive in only 20-40% of OME cases.…”

“…10 Direct culture and PCR results were described using absolute and percentage frequency. The impact of PCR on the results of direct culture was assessed by way of delta percentage (∆%), defined as: ∆ ∆ ∆ ∆ ∆% = final value initial value x 100 initial value (2) and Corynebacterium auris (2).…”

“…Temos, sim, uma mesma doença atravessando estágios evolutivos crescentes de eventos epiteliais e subepiteliais. Esta transição entre tais estágios far-se-á em um ou outro sentido dependendo basicamente do agente agressor, da orelha agredida e da atenção terapêutica que este paciente recebeu no curso de sua doença 5,10,15 . A concomitância de um processo patológico crônico da orelha média em um mesmo paciente já foi assunto de alguns trabalhos 13,16 16 (1996) descreveram uma série de 493 OCL de pacientes com indicação de cirurgia otológica para OMC (OMC C e OMC NC).…”

“…A OMC, sem dúvida, representa uma das grandes áreas de interesse dentro da otorrinolaringologia moderna, tendo em vista a ampla variedade de material de pesquisa publicado a respeito do assunto na literatura pertinente 5,6,7,8 . Talvez o ponto de maior interesse dentro do capítulo OMC seja exatamente a sua patogênese.…”

“…A caracterização do tipo de efusão pode ser dificultada pela opacificação e edema da membrana timpânica 1 . A OME é geralmente considerada uma continuação direta do processo inflamatório que ocorre durante episódi-os prolongados ou recorrentes de otite média aguda (OMA), o que fica comprovado não só pelo fato de quase todos os casos de OME sucederem episódios de OMA, como também por estudos experimentais em animais 2,3 . A origem infecciosa da OME é apoiada pelo acima referido.…”
