Tomographic diagnosis of palatal defects.

We present the results of a pilot study conducted to evaluate the effectiveness of palatal tomography in patients suspected of having palatal defects not detectable by other methods. Twelve patients were involved in the projects, ranging in age from 3 to 11 years. There were 8 boys and 4 girls. Each patient was evaluated with voice recordings, lateral cineradiographic x-rays, and palatal tomograms. Nine of the 12 patients were found by tomography to have palatal defects that had not been detected either by cineradiography or by clinical investigation, including physical examination of the palate. The results of this study are presented with clinical findings.
