title: Anatomic variations of the bone in sinonasal C.T.
abstract: Coronal plane Computed Tomographic (C.T) Scanning of paranasal sinuses is importannt as a preoperative evaluation tool and providing a road map for Functional Endoscopic Sinus Surgrey. The present study wea crried out on 61 patients of chronic sinusitis who underwent C.T. Scan of paranalal sinus, (coronal section) prior to Functional Endoscopic Sinus Surgery.The incidence of anatomical variations of the bone such as Agger nasi cells, Middle turbinate pneumatisation, Heller's Cells,Paradoxically curved middle turbinate, Deviated septum and Uncinate process variations, etc. were investigated in each C.T.Scan. Mucosal abnormalities in each paranasal sinus were also reported.The purpose of this investigation was to determine the background prevalence of bony anatomical variations and mucosal abnormalities of paranasal sinuses and assess the possile pathogenecity of these findings in patients undergoing evalation for Functional Endoscopic Sinus Surgery.
