Evaluation of Paranasal sinus diseases by CT and histopathological studies
Keywords:Paranasal sinuses, Computed tomography, Histopathology
Introduction: Diseases of the Para nasal sinuses include wide spectrum ranging from inflammatory conditions to neoplasms. Computed tomography (CT) has replaced conventional radiographs as imaging modality of choice for assessment of Para-nasal sinus diseases.Material and Methods: This prospective study was done in the Department of Radiology at a tertiary care teaching Hospital over a period of six months. A total of 70 patients who were referred to our department with clinical suspicion of PNS disease underwent CT evaluation of PNS using 64 Multi slice CT scanner. The patient was then placed on the gantry table in prone position. The coronal scan is taken from posterior margin of sphenoid sinus to anterior margin of frontal sinus. Results: In the present study, a total of 70 subjects were included out of which 41 (58.5%) were males and 29 (41.5%) were females. In our study, most of the subjects were 21-40 years i.e., 34 out of 70 (48.5%) followed by 41-60 years, i.e., 31 out of 70 (31.4%). Deviated nasal septum (DNS) was seen in 24 patients (37.1%) with more common towards right side. DNS towards right side seen in 14 patients (20.0%), DNS towards left side seen in 12 patients (17.31%). In table 7, CT findings of chronic sinusitis in 32 patients (45.7%) followed by inflammatory polyp in 17 patients (24.2%), fungal sinusitis in 13 patients (18.5%), Antrochoanal polyp in 6 patients (8.5%) and Neoplastic in 2 patients (2.8%). Seventy patients were sent for histopathological examination. Non-specific inflammatory changes were most common (45.7%) and least common histopathological finding was Angiofibroma and mucocele (1.4%).Conclusion: Paranasal sinus pathology is very varied with therapeutic and prognostic repercussions. Clinical radiological study is sometimes insufficient and histopathological confirmation is essential.
