[An evaluation of the efficacy of radiation and surgical treatments in tumors of the paranasal sinuses and nasopharynx by using computed tomography].

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.
