Ausência de fluxo aéreo nasal e desenvolvimento dos seios maxilares

Abstract

Os mecanismos responsáveis pelo desenvolvimento dos seios paranasais ainda são pouco conhecidos, o fluxo aéreo nasal segundo uma das teorias propostas seria fundamental ao crescimento e desenvolvimento saudável dos seios paranasais. OBJETIVO: Estudar comparativamente o desenvolvimento dos seios maxilares e a presença de sinusopatia, em um mesmo modelo, na ausência e presença de fluxo aéreo nasal posterior. MATERIAL E MÉTODOS: Estudo retrospectivo transversal de uma série de casos; os exames tomográficos pré-operatórios de 7 pacientes com atresia coanal unilateral, idade média 16.28 anos (± 5,024). Este estudo realizado em um hospital terciário, com pacientes que passaram neste serviço entre os anos de 1994 e 2004. A área dos seios maxilares foi medida com auxílio do programa Auto-Cad. Utilizou-se o teste de Kruskal-Wallis para análise estatística. RESULTADOS: Nesse estudo observou-se seios maxilares simétricos e até mesmo maiores no lado da atresia coanal em 85,71% dos casos, não houve diferença estatística significativa entre os dois lados comparados. Não se observou sinais de tomográficos de sinusopatia neste grupo de pacientes. CONCLUSÃO: Os achados aqui apresentados contrariam a teoria difusamente aceita sobre o papel do fluxo aéreo nasal na saúde e no desenvolvimento das cavidades paranasais.
