Background: There is great impact of chronic rhinosinusitis with polyposis on the quality of life and economy. Even greater than angina and chronic obstructive pulmonary diseases. Many cases don’t respond to systemic corticosteroids or even have contraindications. Here, the endoscopic surgery is indicated as stated by the most recent guidelines.
Objectives: Comparing the intraoperative and postoperative outcomes between the conventional instruments and the microdebrider in removing nasal polyps.
Methods: This is a prospective randomized controlled study conducted on 100 patients diagnosed as resistant chronic rhinosinusitis with polyposis in Aswan University Hospital. 50 patients underwent endoscopic sinus surgery using the conventional instruments and the other group, the microdebrider. Comparing the intraoperative blood loss, field visibility and the duration of operation. In addition to the postoperative patient satisfaction and endoscopic improvement between the 2 groups.
Results: Our study revealed significant differences in most of the intraoperative and postoperative variables in favor of using the microdebrider for nasal polyposis.
Conclusion: The microdebrider is preferred by most surgeons to improve field visibility, reduce the operative time along with amount of blood loss and achieving patient satisfaction early postoperatively.
