Chronic rhinosinusitis (CRS) is an inflammatory condition of nasal and paranasal mucosa. It has both medical and surgical modalities of treatment. The evaluation of clinical profile of a patient can be done both subjectively using SNOT 20 scoring and objectively using Lund and Mackey endoscopic scoring and NCCT for imaging for assessment of efficacy of the treatment modality. The most effective modality of treatment of CRS has always been a debate amongst surgeons both in respect to modality as well as timing and type of surgical intervention. In our study we have evaluated the subjective and objective outcomes of FESS in patients with CRS, refractory to medical treatment or with reccurence of disease. In right hands FESS is associated with very low complication rate. There is a marked improvement in the clinical profile as well as the quality of life of patients of CRS following FESS.
