Endonasal sinus surgery aims to preserve mucosal lining while limiting intervention to removal of obstructive bone at the duct isthmus. Transnasal ethmoidectomy removes ethmoidal septa, middle turbinate, and creates broad fenestrations of the sphenoid sinus and frontal infundibulum, aided by a suction‑irrigation endoscope and refined instruments that enhance exposure and reduce complications. Postoperative care following transnasal ethmoidectomy yields excellent clinical outcomes.
Endonasal sinus surgery aims at the preservation of a lining mucosa in the reventilated and redrained cavities. It can, therefore, be confined to the removal of narrowing bone at the "isthmus" of the ducts or windows. Transnasal ethmoidectomy for diffuse polyposis consists of the removal of the ethmoidal cell septa, including the middle turbinate, and a broad fenestration of both the sphenoid sinus and the frontal infundibulum. A consequent postoperative care provided, transnasal ethmoidectomy offers excellent clinical results. A new suction-irrigation endoscope and refined instruments contribute to improved surgical exposure and to the avoidance of complications.
