The purpose of this work was to compare glenoid fossa dimensions and craniofacial morphology on the basis of standard lateral roentgenograms. To overcome the difficulties encountered in making exact measurements on living subjects, 59 dry skulls were used. Eight angular measurements were taken to describe the form of the skull base, mandible, and articulating surface of the glenoid fossa, four linear measurements to describe the position of the fossa, and one to describe the size of the whole skull. A close relationship was observed between the morphology of the articulating surface of the glenoid fossa and the mandibular morphology. The skull base angulation was associated with the position of glenoid fossa in two ways. Basically, the position of the fossa is related to skull base characteristics, but the location of the articular eminence in relation to the clival plane suggests that the mandibular condyle may cause a remodeling of the eminence anteriorly when the glenoid fossa otherwise is translocated posteriorly in association with the flat skull base.
这项工作的目的是基于标准的侧位X线片比较关节盂窝尺寸和颅面形态。为克服在活体上进行精确测量时遇到的困难，使用了59个干燥颅骨。采用八个角度测量来描述颅底、下颌骨和关节盂窝关节面的形态，四个线性测量来描述关节盂窝的位置，一个测量来描述整个颅骨的大小。观察到关节盂窝关节面形态与下颌骨形态之间存在密切关系。颅底角度与关节盂窝位置以两种方式相关。基本上，关节盂窝的位置与颅底特征有关，但关节结节相对于斜坡平面的位置表明，当关节盂窝因扁平颅底而向后移位时，下颌髁可能会导致关节结节向前重塑。
