Our goal was to compare the efficacy of CT with that of plain film radiography (PFR) in analyzing the three-dimensional shape and structure of cystic jaw lesions.
Twenty patients with cystic lesion of the jaw were studied by PFR and CT. The three-dimensional outline of the cyst and the distances between the cyst wall and adjacent vital teeth, cortical jaw bone, maxillary sinus, and mandibular canal were estimated on PFR and on CT scans.
Computed tomography was superior to PFR in the demonstration of the three-dimensional bony margins of the cyst and in determination of its proximity to adjacent vital structures (p < 0.01, sign test).
Application of CT is useful for diagnosis and treatment planning of cystic lesions of the jaws.
我们的目标是比较CT与平片放射摄影（PFR）在分析颌骨囊性病变的三维形状和结构方面的疗效。
对20例颌骨囊性病变患者进行了PFR和CT检查。在PFR和CT扫描上估计囊肿的三维轮廓以及囊肿壁与相邻恒牙、颌骨皮质骨、上颌窦和下颌管之间的距离。
在显示囊肿的三维骨边缘以及确定其与相邻重要结构的接近程度方面，计算机断层扫描优于PFR（p < 0.01，符号检验）。
CT的应用有助于颌骨囊性病变的诊断和治疗计划制定。
