Three-dimensional (3D) CT imaging was performed on three cases (one unilateral, two bilateral) of coronoid process hyperplasia. This technique displayed the impingement of the enlarged coronoid process on an exostosis on the lower border of the malar bone. In addition, a small concavity was found on the inner surface of the malar bone that was not displayed by other imaging modalities. The 3D images were useful in planning surgical treatment. In cases of limitation of opening, finding a malar exostosis on conventional radiographs such as a Water's view should suggest the presence of coronoid process hyperplasia even if the impingement cannot be demonstrated.
对3例（1例单侧，2例双侧）冠状突增生患者进行了三维（3D）CT成像。该技术显示了增大的冠状突对颧骨下缘骨赘的撞击。此外，在颧骨内表面发现了一个小凹陷，这是其他成像方式未显示的。3D图像有助于手术治疗方案的制定。在张口受限的病例中，即使在传统X线片（如华氏位片）上无法显示撞击情况，但发现颧骨骨赘时也应提示存在冠状突增生。
