title: [Role of computed tomography in malignant tumors of the oral cavity and pharynx].
abstract: The CT findings of 22 patients with histologically verified malignant tumors of the oral cavity and pharynx were evaluated to demonstrate the value of CT. Comparison with conventional radiological methods was made. In 16 patients an attempt was made to define tumor expansion and 6 patients were examined after surgery and radiation therapy with regard to tumor recurrence. In the first group we found tumors of different stages: in advanced cancer it was evident that with CT it is possible to describe tumor expansion very exactly and its relationship to surrounding structures, as well as the invasion of the intracranial space or spinal cord. In malignomas of the tongue and mouth floor measurements of size by CT were very precise, as proved by surgery. Our results in the first group of patients show, that CT has a great influence on therapeutic management and is also very important for clinical staging of these malignomas. In the second patient group it is shown that by CT differentiation between postoperative changes and recurrent tumor is as difficult as it is in other organs. Based on the postoperative examination, appropriate follow-up is necessary.
