Sitthiseripratip K 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.
