[Characteristics of maxillary sinuses imaging on various orthopantomograms (Experimental study)]

Presents the results of experimental study of image distortions emerging in various methods of obtaining panoramic sonograms of the maxillary sinuses. Direct panoramic sonograms obtained with the OP-6 Sonarc orthopantomographer were found to give the most objective sizes of the intracavitary formations and their sites. The bottom of the orbit is detectable only on such sonograms. Inaccurate positioning of the head involve image distortions.
