Panoramic zonography in ear radiography.
Thirty ears in 15 patients were examined by plain film radiography and by panoramic zonography with two tracks: A cylindrical concave image layer with 26 mm. radius and a paired sagittal image layer, at 51 mm. distance from midline. The films were interpreted according to the visibility of 23 different anatomic details. On panoramic films the visualization was better in 14 details, equal in 6 and worse in 3 compared to the plain films. The result suggests that panoramic techniques can replace conventional radiography of the ear.
