This study was undertaken as a comparison in detection of bony defects in the maxillary sinus. Comparison was done experimentally on dry skulls using panoramic radiography, Waters' projection, and computed tomography( CT ). Bony defects with diameters of 5mm, 7mm, and 10mm were simulated for maxillary abnormality. Bony defects were placed in the center, the medio-superior region( adjacent to the pterygopalatine fossa ), the latero-inferior region( above the maxillary tuberosity ), the lateral region( adjacent to the zygomatic process of the maxilla ) of the posterior wall of the maxillary sinus and the zygomatico-alveolar region of the maxilla.The results were as follows: 1. Bony defects with diameters of more than 5mm in every area of the posterior wall of the maxillary sinus are best demonstrated by CT. 2. Bony defects, with diameters of more than 5mm in the latero-inferior region of the posterior wall of the maxillary sinus and in the zygomatico-alveolar region of the maxilla, are better shown by panoramic radiography. Bony defects with diameters of more than 7mm in the medio-superior region of the posterior wall, also, are better shown by panoramic radiography. 3. The waters' projection was only able to detect bony defects with diameters of more than 5mm in the zygomatico-alveolar region of the maxilla.

这项研究是作为一个比较检测骨缺损的上颌窦。在干燥的颅骨上，使用全景X线摄影、沃茨投影和计算机断层扫描（CT）进行了实验性比较。模拟直径为5 mm、7 mm和10 mm的骨缺损用于上颌骨异常。分别在上颌窦后壁中央、翼腭窝附近的中上区、上颌结节上方的外下区、上颌窦后壁外侧区、上颌颧牙槽区等部位设置骨缺损。上颌窦后壁各区域直径大于5 mm的骨缺损最好通过CT显示。2.上颌窦后壁外下区和上颌骨颧牙槽区直径大于5 mm的骨缺损，全景X线片显示效果较好。后壁中上部直径大于7 mm的骨缺损，全景X线片也能更好地显示。3.沃茨投照仅能发现上颌骨颧-牙槽区直径大于5 mm的骨缺损。
