Functional endoscopic sinus surgery (FF-CS) has become one of the most common surgical methods for treatment of chronic and recurrent sinusitis. To evaluate objectively the nasal airway patency of patients undergoing FESS, 30 patients with rhirtosinusitis and Nasal polyposis were selected from out-patient clinic of Benha university hospital in the period from July 2000 to February 2001. They were classified into two groups, the 1st group "22 patients" had rhinosinusitis alone and the 2nd group" patients" had Nasal polyposis. They were evaluated pre operatively and 3 months post operatively by Active Anterior Rhinomanometry. It was found that 1st group showed subjective improvement in Nasal resistance to airflow after FESS but rhinomanometric studies showed no significant differences between pre and postoperative measures, while, the 2nd group showed both subjective and objective improvement i.e. less nasal resistance to airflow after FESS, which can be measured significantly by active anterior rhinomanometry and the difference between pre and post operative measures was clear.
