Histopatologia da lâmina própria do seio maxilar na rinossinusite crônica

Abstract

A rinossinusite crônica é definida de modo simplificado como uma inflamação crônica da mucosa nasossinusal. OBJETIVO: Na tentativa de entender o porquê das falhas terapêuticas. FORMA DE ESTUDO: Caso-controle. MATERIAL E MÉTODO: Decidimos estudar as alterações inflamatórias ultraestruturais encontradas na lâmina própria do seio maxilar de 13 pacientes portadores de rinossinusite crônica (RSC) e polipose nasossinusal (PNS), submetidos a tratamento cirúrgico. Biópsias da parede súpero-lateral do seio maxilar desses pacientes foram colhidas durante o ato operatório e, após preparação, observadas através de microscopia eletrônica de transmissão. RESULTADO: Na análise dos dados obtidos, observou-se cinco padrões de resposta inflamatória nas lâminas próprias estudadas inflamatório crônico. Processo inflamatório agudo - 1 caso; processo inflamatório não agudo e não crônico - 5 casos; processo inflamatório crônico - 2 casos; processo inflamatório desorganizado - 4 casos; processo inflamatório indeterminado - 1 caso. Concluindo, a análise dos resultados mostrou que a lâmina própria do seio maxilar desses pacientes esteve infiltrada por células inflamatórias, sem predomínio específico de qualquer elemento celular. Elementos glandulares não foram observados nos casos estudados e a fibrose foi notada em quase metade deles, com intensidade variada e localização preferencial logo abaixo do epitélio. CONCLUSÃO: Na situação vista, o processo inflamatório não seguiu as etapas normais de evolução, mostrou marcante desorganização do processo inflamatório, dificuldade em caminhar até a resolução do quadro, acompanhando a mesma dificuldade de resolução clínica nos pacientes.
