Abstract
Computed tomography was performed on 5 patients with paranasal sinus diseases with unilateral exophthalmos, i. e., mucocele of the frontal sinus, mucocele of the anterior ethmoidal sinus, posterior ethmoidal and sphenoidal cysts, postoperative maxillary cyst and maxillary carcinoma.
Computed tomography showed the position of these lesions, their extension into the orbital cavity and the defect of the bony wall more clearly than plain rentogenography and tomography. These findings were confirmed at operation.
Computed tomography is useful for diagnosis of paranasal sinus disease, especially posterior paranasal sinus disease, postoperative maxillary cyst and carcinoma, as well as for the follow-up study of paranasal sinus disease.
