OBJECTIVES
This study evaluates interobserver and intraobserver agreement with respect to the determination of the shape and surface of the condylar head on panoramic views.
STUDY DESIGN
Detailed frames (n = 632) were made from preoperative and postoperative panoramic views of 158 consecutive patients, who underwent orthognathic surgery. The intraobserver and interobserver agreement were calculated by using Cohen's kappa.
RESULTS
By using Cohen's kappa, the intraobserver agreement was determined to be reasonable or good for surface and shape of the condyle. The interobserver agreement was mediocre or poor for surface and shape of the condyle.
CONCLUSION
Because of the subjectivity of using panoramic views to determine the shape and surface of the condylar head, considerable interobserver disagreement is possible.
目的
本研究评估在全景片上确定髁突头部形状和表面时观察者间及观察者内的一致性。
研究设计
从158例连续接受正颌手术患者的术前和术后全景片中制作详细图像（n = 632）。采用Cohen's kappa计算观察者内和观察者间的一致性。
结果
使用Cohen's kappa，观察者内一致性对于髁突表面和形状被判定为合理或良好。观察者间一致性对于髁突表面和形状为中等或较差。
结论
由于使用全景片确定髁突头部形状和表面存在主观性，观察者间可能存在相当大的分歧。
