| Abstract | |
| The purposes of this study were 1) to depict normal and pathologic states in reconstructed sagittal images of
the maxilla, and 2) to assess how much additional information could be gained by the routine use of sagittal images. In normal subjects,
we made a comparison between sagittal and axial images of ten anatomical structures in the maxilla among 100 CT images and analyzed the
data With Mann-Whitney's U-test. A pathologic study of 50 cases included 25 cases of odontogenic maxillary sinusitis, 7 pleomorphic adenomas,
10 postoperative maxillary cysts, and 8 nasopalatine duct cysts. We made a comparison between axial and sagittal images regarding the
position and extent of the pathological lesions. In the result of normal subjects, the diagnostic value of sagittal images for assessment
of the maxilla was statistically significant for 9 of 10 anatomical structures in the maxilla. In the pathologic study, the sagittal
images showed lesions jo the maxilla of alI 50 patients. Sagittal images were superior to axial images for observing the relationship
between these lesions and the maxilla, lo conclusion, this study has shown that reconstructed sagittal CT images add diagnostic information
to that obtained from axial images. Recon structed sagittal images are therefore recommended as a supplement to axial plane CT imaging
in the evaluation of lesions in the maxilla.
