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.

本研究对上颌窦骨缺损的检测进行了比较。采用全景X线片、Waters‘s投影法和CT对干燥的颅骨进行了实验比较。模拟上颌骨畸形的直径分别为5 mm、7 mm和10 mm的骨缺损区。骨缺损位于上颌窦后壁中央、翼腭窝附近的中上区、上颌结节上方的侧下区、上颌窦后壁的外侧区(毗邻上颌颧突)和上颌骨的颧牙槽区。结果表明：1.CT对上颌窦后壁各部位直径均大于5 mm的骨缺损显示最佳。2.上颌窦后壁外侧下部及上颌颧骨-牙槽区直径>5 mm的骨缺损，全景片显示较好。后壁中上段直径大于7 mm的骨缺损处，全景X线片显示较好。3.水域投影法只能检出上颌颧骨-牙槽区直径大于5 mm的骨缺损区。
