Abstract
The mainstay of frontal sinus surgery for chronic rhinosinusitis is to achieve and maintain an adequate frontal outflow tract. Using a stepwise approach and identifying critical endoscopic anatomic landmarks, to minimize complications and obtain long-term good endoscopic surgical results, should achieve this. The goal is to relieve the patient's symptoms, restore functional mucociliary flow, achieve a wide frontal sinus ostium and prevent long-term scarring and stenosis. Meticulous dissection and appropriate use of instrumentation and techniques aids in preventing unnecessary damage to normal mucosa while achieving one's goal of an adequate surgical ostium.
