Avaliação pulmonar em pacientes portadores de polipose nasossinusal e sua evolução após tratamento cirúrgico / Pulmonary assessment of patients with sinonasal polyposis and their evolution after surgical treatment

RESUMO

Este estudo tem como objetivos: Comparar espirometria de pacientes portadores de polipose nasossinusal (PNS) com grupo controle; correlacionar achados clínicos e de espirometria nos pacientes com PNS; avaliar evolução pulmonar dos pacientes com PNS após tratamento cirúrgico. Foram avaliados prospectivamente 31 pacientes com PNS e 26 do gupo-controle. Encontramos que 45,2 por cento dos pacientes com PNS apresentaram asma enquanto 87 por cento apresentaram alteração espirométrica. Pacientes com PNS apresentaram alteração do VEF1/CVF significativamente maior do que os do grupo controle; pacientes com PNS apresentaram alterações significativas à espirometria; após cirurgia houve melhora clínica em pacientes asmáticos e espirometria inalterada / Controversy existsin the literature regarding the prognosis of asthma and pulmonary function in response to sinonasal polyposis (SNP) surgery. Objectives: To compare spirometry between patients with SNP and a control group, to correlate the clinical findings and spirometry in patients with SNP after surgical treatment. Methods: Thirty-one patients with SNP were prospectively studied. The control gropu consisted of 26 adult volunteers without a history of asthma and SNP. The Student t-test, chi-square test, ANOVA and Wilcoxon test were used for statistical analysis. Results: Asthma was present in 45.2 per cent of the patients, where as 87 per cent showed spirometric alterations. Significantly greater changes in the FEV1 / FVC ratio were observed in patients with SNP compared to the control group. Patients with asthma and altered spirometry showed clinical improvement after surgery. Conclusions: àtients with SNP show significant alterations upon spirometry, asthma is common and spirometry alterations are frequent. Clinical improvement was greater than improvement of pulmonary function...
