  • Abstract
  • Look Inside

 Thirty-nine cases of various paranasal lesions were investigated using B-mode ultrasonography, CT-scan, conventional x-ray and tomography. Lesions include chronic sinusitis, carcinoma of the maxillary sinus, postoperative mucocele, and hemangioma.

 All cases were operated upon and the operative findings were compared to the images obtained by ultrasonography and CT-scan.

 CT-scan is superior to ultrasonography in that the spatial distribution of the lesions are precisely shown.

 Ultrasonography, however, is superior to CT-scan in that the fluid content and mucosal quality are better analized.

 Ultrasonography in B-mode will add much to the image diagnosis of paranasal lesions.
