RESUMO
A total of 106 patients suffering from tumors and inflammatory diseases of the head and neck were investigated. CT was performed in axial and frontal projections using a method of intravenous contrast image enhancement. The purpose of CT was to reveal an abnormal lesion, to detect its initial site, spreading, to make differential diagnosis, and to evaluate therapeutic results. Some limitations of CT in differential diagnosis of small-size tumors were observed. CT can be used for differential diagnosis of tumors and inflammatory processes in the accessory nasal sinuses. CT results were important for a choice of therapeutic methods, radiation therapy design, assessment of efficacy of surgical and radiation therapy, and the detection of tumor recurrences.
