Computed tomography plays imported role in making diagnosis of various lesions. (CT) is the gold standard for the exact delineation of paranasal sinus (PNS) bony anatomy ,extent of disease and also helps in characterization of lesion.
Aim &Objective: To evaluate various Sino nasal masses, evaluate the sensitivity and specificity of CT in diagnosing Sino nasal masses and correlate CT findings of various Sino nasal masses with their histopathological findings.
Method: This study is a prospective correlational study that will include 51 patients evaluated over a period of 1.5 years with suspected Sino nasal masses referred to the Department of Radiodiagnosis from the ENT department via using a Siemens 128-sliceMultidetector CT scan machine at the Department of Radiodiagnosis at Gajra Raja Medical College Gwalior.
Result: PNS lesions were common in males37 (72.5%), commonest age group affected was found to be 11-20 years (21%), 21-30(19.6%) years,31-40, and 51-60 (17.6%). the benign lesion shows 97.14% sensitivity and 100% specificity with 98.04% accuracy. The malignant lesion shows 100.00% sensitivity and 93.02% specificity with 94.12% accuracy. Inflammatory/infective lesions show 62.50% sensitivity and 97.67% specificity with 92.16% accuracy.
Conclusion: CT scanning is an indispensable diagnostic modality in the detection and management of Sino nasal masses, Benign lesions are diagnosed very accurately,andthe Distinction between papilloma, haemangiomas, Sino nasal malignancies, and invasive chronic fungal sinusitis with bone destruction is still debatable.
