Abstract :

Introduction: Chronic rhino sinusitis (CRS) is a wide spread inflammatory disorder of nose and paranasal sinuses and is one of the most common health complaints in individuals every year worldwide and its prevalence is rising^1–2. The osteomeatal complex is the key area to pathogenesis of chronic rhinosinusitis³. Endoscopic surgery aims to eliminate disease in the primary site and allow resolution of the secondary infection in the larger sinuses⁴ .pre–operative CT scan has proven invaluable to otolaryngologists^5&8.In some cases of chronic rhinosinusitis there may be variations in findings between pre–operative CT scan and FESS. So, in this study we aim at correlation between pre–operative CT scan findings of anatomical defects and mucosal assessment and operative finding during endoscopic sinus surgery.

Method: 100 patients with chronic rhinosinusitis were studied for one Year CT scan findings were correlated with intraoperative findings during functional endoscopic sinus surgery.

Result: it is more common in males and between age group 20–30, in mucosal disease maxillary sinusitis was better identified in CT, anterior and posterior ethmoid sinutitis was seen well in endoscopy. Structural abnormalities of middle turbinate were better identified in ESS.

Uncinate process attachment variations, agar, were better accessed on CT.In the assessment of sphenoethmoidal recess, accessory maxillary ostium, sphenoid sinus ostium, adenoid status, inferior turbinate abnormality, lateral sinus, DNS endoscopy is better.In delineating anatomical variations of sphenoid sinus, ethmoid roof, optic nerve course, internal carotid artery, olfactory fossa, frontal sinus pneumatization, vomer pneumatization, maxillary sinus hypoplasia, intrasinus mucosal disease CT is better.

Conclusion: CT is mandatory as preoperative evaluation in patients undergoing ESS, as it provides a road map to surgery. Sometimes the disease could be missed on CT but present on endoscopy in the same way findings seen on CT may be missed on endoscopy
