Outcome of endoscopic sinus surgery in patients with symptomatic chronic rhinosinusitis with minimal changes on computerised tomography.

Abstract

This study was designed to assess the efficacy of functional endoscopic sinus surgery (FESS) in chronic rhinosinusitis (CRS) patients with minimal radiological findings, and based on one centre, prospective randomized controlled study, conducted in the Department of Otorhinolaryngology, Lady Hardinge Medical College, New Delhi. All the CRS out-patients (>18years) refractory to 3weeks of medical therapy were radiologically evaluated with computerised tomographic scan (CT) of nose and paranasal sinuses. These patients were grouped based on CT scoring (Lund Mackay staging system): group A (CT score 0-6) and group B (CT score 7-24); with 35 patients in each group. All the patients underwent FESS using Messerklinger technique. Symptom scoring of all the patients was done using visual analog scale preoperatively and postoperatively at 1-, 3-, 6- and 12-month follow-up. CRS patients with minimal evidence of disease on CT showed statistically significant improvement in symptom scores after FESS. There was no significant difference noted in the overall symptom score improvement as well as for improvement in specific symptoms in both the groups. Further, there was no correlation between the pre-operative symptoms and CT scores. A good subjective outcome in terms of symptom improvement can be obtained with FESS in patients with CRS with minimal evidence of disease on CT.
