INTRODUCTION AND OBJECTIVES Endoscopic sinus surgery is currently the surgical procedure chosen in cases of sinonasal polyposis refractory to medical treatment. The aim of this study was to show our experience in managing such patients operated using endoscopic sinus surgery. METHOD A retrospective study of 246 patients with chronic rhinosinusitis and nasal polyps who were operated by endoscopic surgery. We studied the characteristics of the population, symptoms, grade of affectation, complications and recurrences. RESULTS The most frequent comorbidity was asthma (34.6%) and its relationship with Samter's triad (16.3%). Grades 2 and 3 polyposis prevailed according to Lildholdt staging by nasofibroscopy, coinciding with the radiological preoperative staging. The microdebrider did not shorten surgical time but it lowered complications. Reducing the average stay with the use of absorbable haemostatic agents and their effectiveness in controlling hemostasis were statistically significant. We found 23.2% complications, with only one (.4%) being a major complication; the rest were minor complications, with synechiae as the most frequent (16.3%). CONCLUSION Endoscopic sinus surgery is a minimally invasive and safe technique. Absorbable haemostatic agents are an effective alternative to get complete and stable hemostasis, reducing mean hospital stay. Synechiae continue being the most frequent complication. The fact that many patients recurred but without complications speaks in favour of a natural evolution of the disease and not of the influence of technique.
