A comparative evaluation of computed tomography and laryngography.

A prospective study of 66 patients was conducted to evaluate the relative merits of computed tomography (CT) and laryngography in the assessment of laryngeal disorders. CT complemented direct laryngoscopy and biopsy for treatment planning and was superior to both modalities for showing deep infiltration, invasion of cartilage, and extension to the soft tissues of the neck. The subglottic space can be studied adequately by CT, which could also be useful in diagnosis of lymph node metastases. Distortion of the thyroid cartilage can be shown by CT. CT was equal to or better than laryngography in approximately 90% of cases.

Computed tomography of the injured larynx.

Computed tomography (CT) permitted a much more detailed appraisal of laryngeal dysfunction in patients with blunt laryngeal trauma (8 cases) and iatrogenic injury caused by radiation therapy (7 cases), surgery (2 cases), or intubation (1 case). In thyroid cartilage fractures, the fragments may be widely displaced. The cricoid ring breaks in two places, frequently involving the signet. CT facilitates diagnosis of the mechanism of injury based on the site and extent of fractures. The patterns of distortion and fibrosis of the laryngeal cartilage following radiation therapy may be manifested as encroachment on the airway, easily mistaken for recurrent tumor or localized edema. Minor distortion probably escapes detection on clinical examination. The authors consider CT the examination of choice in laryngeal injury.

Extensions of paranasal sinus tumors and inflammatory disease as evaluated by CT and pluridirectional tomography.

CT and pluridirectinal tomography are compared in their ability to show the extent of paranasal sinus tumors or benign aggressive processes. Thirty-one cases are reviewed; CT was superior to pluridirectional tomography in showing spreads of tumor to all clinically important areas, including the infratemporal fossa, nasopharynx, orbit, and intracranial compartment. CT not only consistently allowed less equivocal interpretation, but also enabled us to qualify orbital involvement as intra- or extraconal, and to quantitate better both brain and infratemporal fossa involvement. We feel that CT scanning is the better way to determine the extent of such pathology.

Computed tomography in the evaluation of mediastinal lipomatosis.

Mediastinal abnormalities can present a challenging differential diagnosis. One of the many causes of superior mediastinal widening is excess deposition of fat or mediastinal lipomatosis. Mediastinal widening was evaluated by routine chest radiography, conventional tomography, and computed tomography in four patients with steroid induced Cushing's syndrome or simple obesity. Computed tomography was the only modality that definitively diagnosed mediastinal lipomatosis in each case.

The role of computed tomography in the management of cancer of the larynx.

Computed tomography (CT) offers a unique method of displaying the anatomy of laryngeal cancer. Asymmetrical contours of the thyroid cartilages have been found as a normal variant. Marked asymmetry may indicate buckling of the cartilage which could contribute to acute airway obstruction following radiation therapy. A low-density, soft-tissue plane medial to the thyroid cartilages may prove valuable in evaluating cartilaginous involvement with tumor. Computed tomography should make a significant contribution to more accurate planning of radiation therapy portals by showing the relationship of lymphatic spread to the primary tumors.

Computerized tomography scanning of the temporal bone.

Computerized tomography (CT) scanning has reached a degree of sophistication that requires alteration of technical factors to demonstrate different parameters of temporal bone pathology. The techniques for pontocerebellar angle display, eustachian tube, middle ear pathology, and overall temporal bone display are quite different. Close cooperation between the radiologist and otologic surgeon are required for optimal use of CT scanning advances.
