Background: Common teardrop-shaped growths in the nose or paranasal sinuses are called nasal polyps. Although they can grow in any paranasal sinus, the middle meatus and osteo-meatal complex region is the most preferred location. The present study was conducted to assess utility of endoscopic sinus surgery in management of ethmoid polyps. Materials &Methods: 85 adult patients of ethmoid polyps of both genders were enrolled. Under general anesthesia, FESSwhich includes middle meatus antrostomy, posterior and anterior ethmoidectomy, and frontal recess clearancewas scheduled. The severity of each symptom was assessed based on 4-point semiquantitative scale. Results: Out of 85 patients, 50 were males and 35 were females. Anosmia score was 2.64 pre- operatively and 1.36 post- operatively. Pre- operative rhinorrhoea score was 2.52 and post- operative score was 2.02, nasal congestion score was 3.84 pre- operatively and 2.40 post- operatively. Nasal hyperreactivity score was 1.94 pre- operatively and 1.12 post- operatively. A significant difference was observed (P< 0.05). Common complications recorded in patients undergoing FESS were synechia in 1 case, CSF leak in 2 and ocular problem in 1. A significant difference was observed (P< 0.05). Conclusion: The cases of ethmoid polyps were successfully treated with functional endoscopic sinus surgery. There were very few issues noted, including synechia, eye issues, and CSF leaks.
