    Abstract:
    A total of 40 patients with benign and malignant paranasal sinusal and nasopharyngeal tumors were examined to evaluate the effectiveness of radiation and surgical treatment with the help of computerized tomography (CT). The aim of CT examinations was to reveal CT findings of radiation pathomorphosis of a tumor mass and contiguous tissue, to determine their CT structure, and to find residual masses after the treatment. CT findings of three stages of tumor radiation pathomorphosis were determined. Besides, sings of a radiation reaction of the paranasal sinusal mucosa and consequences of cerebral radiation necrosis were described. Some criteria of objective assessment of the results of radiation and surgical treatment of paranasal sinusal and nasopharyngeal tumors were proposed.
