[Functional endoscopic sinus surgery. Evaluation methods and results].

Functional Endoscopic Sinus Surgery (FESS) is now undoubtedly the choice procedure for the surgical treatment of chronic sinusitis and nasal polyposis after failure of medical treatment. Between January 1990 and December 1992, 51 patients with chronic sinusitis and 44 with nasal polyposis who underwent FESS were evaluated (170 ethmoidectomies). Preoperative evaluation is obtained through personal scaling combined with a CT of the sinuses, whereas postoperative assessment is based on the same scoring together with an endoscopic evaluation. Good functional results and no significant differences between the two types of pathology are obtained after a 1 year follow-up.
