Outcome of Endoscopic Sinus Surgery in Inflammatory Sinonasal Patients: A Descriptive Study

Various systems of Computerized Tomographic (CT) staging and scoring have been applied to define the extent of sinus abnormality and the degree of mucosal thickening. Functional Endoscopic Sinus Surgery (FESS) has been used with considerable success rate to treat chronic sinonasal patients unresponsive to medical therapy. This study was designed to investigate the relationship between the result of CT scoring and staging and the outcome of surgery. The one year outcome of FESS together with preoperative CT staging and scoring were determined and compared with each other. Compared to those with higher stages (III and IV), patients with lower preoperative CT stages (I and II) had a significantly higher successful outcome of surgery. CT staging and scoring were obviously correlated. The results of this study show that preoperative CT staging and scoring are two useful means for better prediction of the long–term outcome of surgery one year after FESS.
