Computed tomography of the paranasal sinuses.

The diagnostic value of computer tomography in lesions of the paranasal sinuses has been investigated in three cases with maxillary carcinoma and in five cases with fractures of the facial bones. In most of the cases, particularly in carcinoma, computer tomography was found to provide additional information to that obtained with conventional X-ray techniques. In fractures, however, a supplementary plain film examination was found to be indispensable.
