A cephalometric study was carried out among 25 male and 23 female subjects with excellent occlusion and good facial harmony. The vertical facial heights were measured separately for each sex. The following conclusions were arrived at: 1. There was a significant difference for both Anterior and Posterior Facial Heights between males and females, males having higher values than females. 2. The ratio of Upper Anterior Facial Height to Total Anterior Facial Height remained constant irrespective of the sex. The same ratio was observed on calculation of available data from earlier studies on North Indians and other Indian ethnic groups. This testified that the ratio of Upper Anterior Facial Height to Total Anterior Facial Height has an important contribution to the harmony of face. The ratio can be taken in account rather than absolute linear measurements when studying deviations of the face. 3. The ratio of Lower Posterior Facial Height to Total Posterior Facial Height was observed to remain constant (65%) irrespective of sex. This further emphasis, contribution of posterior Facial Height to excellence of facial harmony. 4. A significant difference was observed between males and females for the ratio of Total Anterior Facial Height to Total Posterior Facial Height. It seems that males have well developed Posterior Facial Height.
对25名男性和23名女性受试者进行了一项头影测量研究，这些受试者咬合良好且面部协调性佳。分别测量了每个性别的垂直面部高度。得出以下结论：1. 男性和女性的前面部高度和后面部高度均存在显著差异，男性的值高于女性。2. 上前面部高度与总前面部高度的比值不论性别均保持恒定。根据对北印度人和其他印度族群早期研究的现有数据计算，也观察到了相同的比值。这证明上前面部高度与总前面部高度的比值对面部协调性有重要贡献。在研究面部偏差时，可以考虑该比值而非绝对线性测量值。3. 观察到下后面部高度与总后面部高度的比值不论性别均保持恒定（65%）。这进一步强调了后面部高度对面部协调性的贡献。4. 男性和女性的总前面部高度与总后面部高度的比值存在显著差异。似乎男性的后面部高度发育良好。
