The present study revealed an advanced method using data obtained from three-dimensional computed tomography (3D CT) to evaluate the craniometric data of the Thai population. Ninty-one Thai cadaveric dry skulls from the Faculty of Medicine, Khon Kaen University were investigated in the present study. It enabled the authors to assess the three-dimensional anatomical landmarks in digital format without physical measurements. The results have revealed that the craniometric data of Thai males were larger than Thai females with a statistical significant difference, especially, the maximum cranial length, basion-bregma height, nasion-basion length, nasion-bregma length and bizygomatic breadth parameters (p << 0.001). In addition, the craniometric data based on Thai skulls of the people in the northeast region was different from the people in the central region. Furthermore, the linear regression equations obtained from the pairwise parameter, it is useful to predict the craniometric parameters in forensic medicine.
