Computed tomography of tumors of paranasal sinuses and face

The CT can image both bone and soft tissue structures of paranasal sinuses and face and so CT has added animportant new dimension to radiological evaluation of disease of paranasal sinuses and face. CT is more accuratemethod of staging of tumors and essential for therapeutic planning. The author studied 25 cases of proven tumorsof paranasal sinuses and face during the period from Oct. 1977 to Aug.1980 in Kyung Hee University Hospital. Theresult were as follows; 1. Among 14 females and 11 males, their age range was form 14 years to 65 year. 2. Thedistribution of tumors were mucocele, squamous cell carcinoma, metastatic carcinoma, meningioma, angiofibroma,Masson's hemangiosarcoma, fibrous dysplasia, neurogenic sarcoma, Schwannoma, hemangioma, epidermoid, transitionalcell carcinoma and unknown. 3. Determination of location and extent of mucocele was easily done by CT. Thus in allcases of esthmoid mucocele, chief complaint of exophthalmos could be easily explained by identification of itsextension into peripheral fat space of orbit. 4. It is our belief that CT was useful method to determine stagingof tumors of paranasal sinuses and was essential in choosing appropriate treatment modality. 5. The contrastenhancement is generally not helpful in pathologic diagnosis of tumors but intracranial extension of tumors areclearly defined by contrast enhancement.
