[Nasal polyposis: postoperative long term results (5 years) after endoscopic sinus surgery]

The purpose of this study is to evaluate the results after endoscopic sinus surgery in cases of nasal polyposis. We include 54 patients with diffuse nasal polyposis suffering from nasal obstruction. An endoscopic sinus surgery under general anesthesia with excision of the polyposis was performed. There were no complications. The patients were followed closely and treated with local and systemic steroids. After 5 years, the 75% of these patients were free of nasal symptoms and in the 67% the mucosa appeared normal. We also review the influence of some factors (ASA triad, anosmia, allergy...) in the recurrence of the disease.
