In-clinic Endoscopic Polypectomy for Chronic Sinusitis With Nasal Polyps

The experimental intervention is endoscopic polypectomy performed in clinic (EPIC) where nasal polyps are removed using a microdebrider under local and topical anesthesia in the outpatient clinic.

The control intervention is endoscopic sinus surgery (ESS), a minimally invasive procedure that is the current standard that involves polypectomy with a microdebrider as well as sinus ostia enlargement of the affected sinuses performed in the operating room under general anesthesia.

ESS will be performed under general anesthesia in the operating room

EPIC will be performed under topical and local anesthesia in a clinic setting
