  • Abstract
  • Look Inside

 The authors obtained direct sagittal CT scans of the head using a new method for positioning the head of patient in sitting position.

 Direct sagittal scans are more useful than computed rearranged scans in a better spatial and density resolution. The triplane CT (axial,coronal, and sagittal CT) greatly improves three dimentional recognition of the intracranial and facial structures and the extent of the. lesion.

 A series of patients with various nasal and oropharyngeal tumors was examined with the triplane CT.

 The advantages of direct sagittal scans are

 (1) the recognition of localization and extension of the lesion.

 (2) the evaluation of the extent of the deep facial and nasopharygeal tumors, especially in the intracranial and intraorbital regions.

 (3) the more accurate determination of staging of the maxillary cancer.
