title: Computed tomography in the diagnosis of diseases of the paranasal sinuses.
abstract: The authors investigated 31 patients suffering from benign and malignant lesions of the paranasal sinuses. Clinical, conventional radiological methods and computed tomography were used. In benign lesions CT added little significant information to that obtained by conventional radiological methods. In malignant lesions, however, CT provides additional valuable information. It gives a clear picture of the posterior, superior and orbital extent of paranasal tumours. It also shows the extent of the tumour into the infratemporal fossa.
