The value of the lateral radiograph in patients who have sustained facial trauma has been assessed. Three observers each assessed 200 sets of facial radiographs randomly containing either three- (occipito mental, occipito mental 30 and lateral) or two-film series (lateral excluded). No additional fractures were detected with three films. A sensitivity of 90% and a positive predictive value of 0.90 was seen with both three and two-film series. Specificity was 99.3% with three films and 97.3% with two films. These differences are not statistically significant. We conclude that the lateral film can safely be excluded from the initial assessment of patients with facial trauma.
已对面部创伤患者的侧位X线片价值进行了评估。三名观察者每人随机评估200组面部X线片，这些X线片组包含三张（枕颏位、枕颏30°位和侧位）或两张胶片系列（不包括侧位）。三张胶片未检测到额外骨折。三张和两张胶片系列的敏感度均为90%，阳性预测值均为0.90。三张胶片的特异度为99.3%，两张胶片的特异度为97.3%。这些差异无统计学意义。我们得出结论，在面部创伤患者的初始评估中可以安全地不使用侧位片。
