STATING BACKGROUND: The clival angle, between the ethmoidal plane and the clival plane, measures the cranial base angulation. Relations between cranial base angulation and facial patterns have been discussed and present contradictory evidence. The aim of this study is to determine whether correlations could be found between the clival angle and craniofacial measurements.
This study was carried out on a sample of 235 human skulls. Twenty landmarks were marked. The clival angle and 16 other variables were measured and compared using analysis of variance.
Statistical analysis showed a relationship between the clival angle and six measurements (P < 0.05). There was a positive correlation between the clival angle and the cranial lengths, the nasomaxillary sagittal measurements and palatal length but the width of the foramen magnum had a negative correlation. No significant relationship was found between the clival angle and the cranial height and widths, the palatal width, the length of the foramen magnum and the mandibular measurements.
The trends found in this study with regard to the craniofacial lengths show that the nasomaxillary complex in humans has a stable position lying beneath the anterior cranial base. Transversal, vertical and mandibular variables have a more independent relationship.
陈述背景：筛骨平面与斜坡平面之间的斜坡角可测量颅底角度。颅底角度与面部形态之间的关系已被讨论且存在相互矛盾的证据。本研究的目的是确定斜坡角与颅面测量值之间是否存在相关性。
本研究对235个人类颅骨样本进行。标记了20个标志点。使用方差分析测量并比较了斜坡角和其他16个变量。
统计分析显示斜坡角与六项测量值之间存在关系（P < 0.05）。斜坡角与颅长、鼻上颌矢状测量值和腭长呈正相关，但枕大孔宽度呈负相关。未发现斜坡角与颅高、颅宽、腭宽、枕大孔长度和下颌测量值之间存在显著关系。
本研究中关于颅面长度的趋势表明，人类的鼻上颌复合体在前颅底下方具有稳定的位置。横向、垂直和下颌变量具有更独立的关系。
