Abstract

The role of computed tomography (CT) in connection with irradiation was evaluated in 60 patients with malignant tumors of the nasal cavity and paranasal sinuses. The extent of the tumors was well demonstrated at CT. The infratemporal fossa was involved in 33 patients, extension to the intracranial cavity was found in 6, and in 16 extension to the contralateral side. Such information is of great help in radiation treatment planning. On the other hand, CT was less valuable for evaluating the effect of radiation therapy.
