A retrospective study was performed to determine the reliability of primary radiography in evaluation of fractures in the mandible. In all, radiographic diagnosis was correct in 77% of 272 fractures. Panoramic tomography (PT) was superior compared with conventional methods (skull films and jaw projections) in the assessment of these fractures. Without PT, the diagnostic error rate increased to 40%, largely due to missed fracture lines. It is recommended that PT be performed in all cases of suspected jaw fractures, initially, when obtainable, or at least once during the treatment of a jaw trauma patient. Fractures in the dento-alveolar and condylar regions, particularly, presented repeated difficulties in initial radiography.
进行了一项回顾性研究，以确定初次X线摄影在评估下颌骨骨折中的可靠性。在272例骨折中，X线摄影诊断正确的有77%。在评估这些骨折方面，全景体层摄影（PT）优于传统方法（颅骨平片和颌骨投照）。若没有PT，诊断错误率会升至40%，这主要是由于骨折线漏诊所致。建议在所有疑似颌骨骨折的病例中，最初若能获得该检查，应进行PT检查，或者至少在颌骨创伤患者的治疗过程中进行一次PT检查。尤其是牙槽突和髁突区域的骨折，在初次X线摄影时反复出现诊断困难。
