Functional endoscopic sinus surgery- a newer surgical concept in the management of chronic sinusitis.

Two hundred and ten patients suffering from chronic hyperplastic rhinosinusitis refractory to medical treatment were subjected to Functional Endoscopic Sinus Surgery using the classical Messerklinger technique ( MT FESS). Of these, 147 (70%) had complete relief of symptoms, 39 (18.5%) had partial relief of symptoms and 15(7.17%) had no/poor relief of symptoms in the follow-up period varying from 6-33 months (Mean 18.3 months). Sine (4.2%) patients were lost to follow-up. The merits and demerits of Functional Endoscopic Sinus Surgery are discussed.
