RESUMO
OBJECTIVE: To determine whether the presence of opacification in the paranasal sinuses of children and adolescents without rhinosinusitis implies an increased risk of later development of upper respiratory tract symptoms. METHODS: This was a prospective study of a cohort of patients aged 0 to 18 years who underwent computerized tomography (CT) scans for indications unrelated to rhinosinusitis. Sinus opacification was evaluated using an opacification/development ratio score. The patients' clinical progression was followed up using a questionnaire for 1 month after the scans. RESULTS: Fifty-six percent (56%) of the 106 patients enrolled in the study had opacity, the majority due to mucosal thickening. Intense opacification was defined as "suspected" (score ≥ 15) and patients in this subset had a greater risk of developing symptoms during follow-up (odds ratio = 2.74; 95%CI 1.10-6.83) compared to those with no findings or discrete findings. CONCLUSIONS: Intense incidental sinus opacity on CT indicates a risk of future development of a clinical respiratory condition.

OBJETIVO: Verificar se, em crianças e adolescentes sem rinossinusite, a presença de opacificações dos seios paranasais implica em maior risco de desenvolvimento posterior de sintomas do trato respiratório superior. MÉTODOS: Estudo prospectivo de coorte, com pacientes entre 0 e 18 anos, submetidos à tomografia computadorizada do crânio por indicações não relacionadas à rinossinusite. As opacificações sinusais foram aferidas pelo escore razão opacificação/desenvolvimento. A evolução clínica dos pacientes foi então avaliada por questionários durante o mês que se seguia ao exame. RESULTADOS: Dos 106 pacientes incluídos, as opacidades acometeram 56 por cento, a maioria de espessamento mucoso. Opacidades intensas, ditas suspeitas (escore > 15), impuseram maior risco de desenvolvimento de sintomas no seguimento (odds ratio = 2,74; IC95 por cento:1,10-6,83), em comparação aos exames normais ou às opacidades discretas. CONCLUSÃO: Opacidades tomográficas sinusais incidentais em crianças e adolescentes oferecem risco de desenvolvimento futuro de quadro clínico respiratório quando intensas.
