Computed tomography of the parotid gland during contrast sialography.

By performing CT scanning during contrast sialography, tumors within the parotid gland can be shown and their configuration in relation to the remaining normal salivary gland and surrounding structures can be appreciated. This permits better evaluation of the relationship of the tumor to the facial nerve, possible extension of tumor beyond the gland, and benign versus malignant growth characteristics

Lateral wall of the olfactory fossa in determining intracranial extension of sinus carcinomas.

The role of plain skull radiography and pluridirectional tomography in determining anterior cranial fossa extension of paranasal sinus tumors is reassessed. The lateral wall of the olfactory fossa, a thin bony plate forming part of the roof of the ethmoid sinuses, is routinely visualized on plain skull radiography and pluridirectional tomography in the coronal plane and serves as an indicator of intracranial tumor extension. In a series of 47 patients with paranasal sinus tumors, 100% true positive and 3% false negative interpretations of the integrity of the lateral wall of the olfactory fossa were made with pluridirectional tomography. Interpretations with plain skull radiography were 90% true positive and 3% false negative. Assessment of the integrity of the lateral wall of the olfactory fossa by these techniques provides an accurate evaluation of the presence of intracranial tumor extension by this route. Computed tomography in the coronal plane with contrast infusion is a useful adjunct.

[Fractures of the facial skeleton].

The radiologist is in the unique position of reviewing the management of facial fractures when interpreting the post reduction films. Many of these patients have other more life threatening injuries so that their facial fractures may have been neglected or treated by individuals unfamiliar with the problem of facial injury. Immobilization following reduction is the key to satisfactory healing. The bony calvarium is the pivotal point and all free fragments should be immobilized to the frontal zygomatic area. Mandibular fractures should be immobilized to the upper alveolar ridge. If the upper alveolar ridge is also a free fragment due to a LeFort type fracture the entire complex of mandible and midface after being wired together should be wired to the stable bony calvarium. Midface fractures (LeFort type fractures) require the same type of treatment as one would apply to a forearm fracture; i.e., the joints proximal and distal must be immobilized. In the midface fracture the mandible is immobilized through the teeth to the upper alveolar ridge and the entire complex to the bony calvarium. The more specific problems associated with individual factors require high quality radiographic techniques for diagnosis and management.

Roentgen findings in occipital pole tumors.

The arteriographic findings of occipital pole tumors consist of the following:1. Anterior displacement and elevation of the middle cerebral group.2. "Accordioning" of the anterior choroidal artery.3. Anterior displacement of the lateral branch of the posterior choroidal artery.4. Local stretching of vessels about the tumor.5. "Onion skinning" of the pial vessels.6. Anterior displacement of the vein of the occipital horn.7. Greater displacement of the internal cerebral vein than of the anterior cerebral artery. Air studies require precise radiographic technique lest the subtle displacements of the occipital horn and trigone area be missed.
