Vertical proportions of face: a cephalometric study.

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.
