Objective To analyze the facial anatomical parameters of normal Mongolian young college students in Inner Mongolia by digital three-dimensional reconstruction and measurement, and to evaluate the differences in facial gender, so as to provide anatomical references for surgical cosmetic surgery and maxillofacial orthodontics. The improvement of facial contours database is to provide aesthetic reference for facial shaping of young Mongolian men and women. Methods Sixty (30 males and 30 females) young Mongolian college students were subjected to three-dimensional facial scanning, and software was used to measure 12 indicators such as head width and morphological face length, as well as head and face indexes. Correlation analysis was performed to compare the indicators, and the facial differences were compared among ethnic groups in different regions. Results The eye slit breadth of the left and right of Inner Mongolian young college students were (31.76 ± 4.81) mm and (31.47 ± 4.34) mm, and there were no statistical significance (P>0.05). The eye slit breadth of the male and female were (35.49 ± 2.74) mm and (27.74±1.99) mm, respectively, and male was greater than female, the difference is statistically significant (P<0.05). There was a statistical difference in head breadth, physiognomic facial height, face breadth, morphological facial height, external biocular breadth between men and women. The differences were statistically significant (P<0.05). The nasal index in terms of gender was (72.55±1.63) and (73.14±1.21), with no significant difference (P>0.05). The breadth-height index of head，morphological facial index，fronto-facial index, lip index were statistically significant (P<0.05). According to the morphological facial index classification, male wide face type was more common (accounting for 46.67%) and the female ultra-wide face type was common (56.67%). According to the classification of nasal index, middle nasal type was more common in male and female, accounting for 50% and 53.33%, respectively. Conclusions Three-dimensional facial indicators of young Mongolian college students in Inner Mongolia are generally larger in males than females. Males are more likely to have wide type, while females are more likely to have ultra-wide types, mid-nasal type is more common in men and women. Compared with other ethnic groups, Mongolian men and women have the characteristics of wide breadth.
