Much cephalometric analyses have been introduced to assist in the orthodontic treatment plans. The aim of this study was to determine facial height dimension in Iranian Kurdish population by lateral cephalometric radiographs, and to assess sexual dimorphism if present, and to compare these standards with Caucasians population. 100 lateral cephalograms of Iranian Kurdish people with normal occlusion were analyzed. Linear measurements were done based on Wylie-Johnson, Siriwat-Jarabak, Gebeck, Merrifield and Horn analysis, and the angles of SN.MP, MMA, MA, SN.GoGn, R-angle, and Y-axis used for angular measurements. There was a statistically significant difference between men and women for LAFH, UAFH, TAFH, LPFH, UPFH, TPFH, LAFH/TAFH, and PFH (P<0.05), so that the mean of these variables in men was less than women. The variables of UAFH/TAFH and SN.MP (P<0.05) in men were significantly more than women. The statistically significant difference was seen between Iranian Kurdish population and Caucasians for TPFH, LAFH, UAFH, TAFH, SN.MP, LPFH, UPFH, and R-angle (P<0/05), so that the mean of these variables in Iranian Kurdish population was more than Caucasians, and The variables of LPFH/TPFH, LAFH/TAFH, and Y-axis (P<0.05) in Caucasians population were significantly more than Iranian Kurdish population. In this study, there was a significant difference between men and women in facial height dimension, so that it seems that vertical growth pattern in women is more than men. Furthermore, Iranian Kurdish population have more facial height dimensions than Caucasians, however, LAFH/TAFH in Caucasians was more than Iranian Kurdish population.
