Computed tomography of the paranasal sinus and nasal cavity tumours

One hundred and thirty seven patients with suspected neoplasms of paranasal sinuses and nasal cavity were studied with conventional radiography and C.T. Scan. Significantly greater tumour extent was detected on C.T. due to 3 - Dimensional demonstration of tumours. C.T.Scan was extremely helpful in diagnosing the primary site of tumour and tumour recurrence in treated cases. This information had pronounced effect on patient management and prognosis determination. C.T. was also helpful in differentiating certain benign conditions such as fibro-osseous lesions and inflammation without bony erosion from malignant tumours. The importance of C.T. scan in these neoplasms is discussed here.
