The aim of the present study was to evaluate how vertical facial height correlates with mandibular plane angle, facial width and depth from a three dimensional (3D) viewing angle.
In this study 3D cephalometric landmarks were identified and measurements from 43 randomly selected cone beam computed tomography (CBCT) images of dry skulls from the Weisbach collection of Vienna Natural History Museum were analyzed. Pearson correlation coefficients of facial height measurements and mandibular plane angle and the correlation coefficients of height-width and height-depth were calculated, respectively.
The mandibular plane angle (MP-SN) significantly correlated with ramus height (Co-Go) and posterior facial height (PFH) but not with anterior lower face height (ALFH) or anterior total face height (ATFH). The ALFH and ATFH showed significant correlation with anterior cranial base length (S-N), whereas PFH showed significant correlation with the mandible (S-B) and maxilla (S-A) anteroposterior position.
High or low mandibular plane angle might not necessarily be accompanied by long or short anterior face height, respectively. The PFH rather than AFH is assumed to play a key role in the vertical facial type whereas AFH seems to undergo relatively intrinsic growth.
本研究的目的是从三维（3D）视角评估垂直面部高度与下颌平面角、面部宽度和深度之间的相关性。
在本研究中，确定了3D头影测量标志点，并对从维也纳自然历史博物馆魏斯巴赫收藏的干燥颅骨中随机选取的43张锥束计算机断层扫描（CBCT）图像进行了测量分析。分别计算了面部高度测量值与下颌平面角的皮尔逊相关系数以及高度-宽度和高度-深度的相关系数。
下颌平面角（MP-SN）与升支高度（Co-Go）和后面部高度（PFH）显著相关，但与前下面部高度（ALFH）或前全面部高度（ATFH）无关。ALFH和ATFH与前颅底长度（S-N）显著相关，而PFH与下颌骨（S-B）和上颌骨（S-A）的前后位置显著相关。
下颌平面角高或低不一定分别伴随着前面部高度长或短。PFH而非AFH被认为在垂直面部类型中起关键作用，而AFH似乎经历相对内在的生长。
