Symptomatic Outcomes of FESS

Abstract

The term 'sinusitis' refers to a group of disorders characterized by inflammation of the mucosa of theparanasal sinuses. Because the inflammation nearly always also involves the nose, it is now generally accepted that 'rhinosinusitis' is the preferred term to describe this inflammation of the nose and paranasal sinuses. Presently, functional endoscopic sinus surgery (FESS) is the standard treatment of chronic rhinosinusitis (CRS) and in sinonasal polyposis. The endoscopic procedure is based on the principles introduced by Messerklinger, which prioritize both the function and the permeability of pre-ethmoidal spaces. In 1985, Kennedy described this technique and popularized the term "Functional Endoscopic Sinus Surgery -FESS".
