OCCURRENCE OF MALIGNANT TUMORS OF PARANASAL SINUSES IN KARNATAKA

Abstract

Introduction: malignancy of paranasal sinuses is wide spread. Paranasal sinuses are in close anatomical relationship with skull viscera. Clinical assessment get hampered by surrounding bony structures, diagnostic radiology is of paramount importance. While conventional plain X ray film demonstrates limited pathologies. CT imaging provides excellent information of the paranasal sinuses and its pathologies then standard radiographs.
Materials and Methods: In this hospital based, prospective co relational descriptive clinic radiological study, All the patients underwent endoscopy or FESS following CT evaluation and findings were correlated.
Results: CT diagnosis had higher sensitivity, specificity, positive predictive value and negative predictive value in diagnosing anatomic variants of PNS, involvement of the bone by PNS lesions was always demonstrated by the CT accurately.
Interpretation and Conclusion: Pathological conditions of PNS are common and have a varied presentation in all the age groups. These are difficult to diagnose accurately on conventional plain films. CT imaging provides detailed information regarding involvement, location, extent of malignancy of paranasal sinuses and is an excellent alternative to standard radiographs.
