Comparison of microdebrider-assisted endoscopic sinus surgery and conventional endoscopic sinus surgery for chronic rhinosinusitis with nasal polyps

Abstract

OBJECTIVE . To study and compare the benefits of microdebrider-assisted endoscopic sinus surgery and conventional endoscopic sinus surgery in terms of subjective and objective improvement in symptoms of nasal polyposis. MATERIAL AND METHODS . This study involved 60 patients with bilateral sinonasal polyposis scheduled to undergo Endoscopic Sinus Surgery. The patients were randomized into two groups: Group A -Conventional endoscopic sinus surgery and Group B -Microdebrider-assisted endoscopic sinus surgery. RESULTS . There was a significant difference in the mean VAS at 3 months postoperatively in Group B, but no significant difference at 6 months postoperatively following either of the two methods. The mean time for surgery (p<0.01) and the mean intraoperative blood loss (p<0.01) were significantly lower in Group B. CONCLUSION . A well-trained surgeon with proper anatomical knowledge, good instruments, hypotensive anaesthesia, minimal mucosal injury and regular proper follow-up will have similar postoperative results with both methods.
