Abstract
Different ethnic groups have different craniofacial framworks and facial features, and there even are some variations between various genders or ages within the same race. Nose is the most prominent facial feature, knowing the sex, age and other variates related alterations of nasal region in varied ethnic groups is crucially important in personal identification and facial recondtruction. To our knowledge, there are no publications of Taiwanese craniofacial and nasal anthropometric study, thus the aim of this study was to create a reference database of craniofacial and nasal regions morphology measurements in Taiwanese population .
We used DICOM software to measure the images of Taiwanese adults(aged 20-80)who underwent brain MRI in National Taiwan University Hospital during January, 2002 to December, 2013. Seventeen linear distances and fourteen angles of mid sagittal plane as well as seventeen linear distances and one angle of different axial planes were surveyed, Furthermore, fourteen propotional indices composed of different linear distances were also calculated.
After statistically analysis the measurement results of 102 males and 87 females, the data revealed men had larger linear distences and smaller angles when compared to women, it suggests that women have smaller face and nose breadths as well as less prominent facial morphology. Nasal linear distances increased with advancing age. Larger BMI group appeared larger linear distences, especially the ones of craniofacial width. The correlations between body height and the craniofacial or nasal linear distances as well as the angles were not vaild.
In this research, we established a database of craniofacial and nasal regions morphology of Taiwanese population We also discussed the the influence of gender, age, body height and BMI on craniofacial morphology. These result can serve as the reference data for forensic facial reconstruction.
