ABSTRACT
Objective: To proform the digital three-dimensional reconstruction and measurement analysis of the normal Mongolian young students' digital anatomical features so to provide anatomical parameters for auricle reconstruction surgery, data measurement for traumatic ear defects, and provide basic data for forensic disability identification. Methods: A total of 32 Mongolian college students used the Artec Spider 3D scanner to perform a three-dimensional scan of the auricle. The 59 sides (28 cases on the left side and 31 cases on the right side) were screened out. Using software measurement according to anthropometry, the ear length and width of the ear, the length and width of the ear, the length and width of the earlobe, and the correlation analysis were carried out. Results: Fifty-nine cases of normal auricle were obtained. The results were as follows: morphological ear length was(25. 72±2. 64) mm, morphological ear width(49. 73± 5. 18)mm, physiognomic ear length(60. 06±4. 89) mm, physiognomic ear width(28. 68±3. 25) mm, earlobe length(15. 71± 2. 67) mm, lobe width(20. 45±2. 92) mm, the morphological ear index was 194. 98±26. 03, and the physiognomic ear index was 47. 91±5. 36. The morphological ear index was calculated to be 194. 98±26. 03, and the physiognomic index was 47. 91 ±5. 36. Conclusion: The symmetry of the auricle is good, and there is a gender difference in the appearance and ear length of the auricle (P<0. 05). There is a difference between the Mongolian nationality and the Han nationality in different regions (P<0. 05). The feature ear length of the Mongolian young college students is similar to that of the Sichuan Han nationality in northwest China. Male physiognomic ear of Han nationality in Henan province between 20 and 29 years old is longer than male physiognomic ear length of 20 to 22 years old in this paper. Male physiognomic ear length of Mongolian young college students are as those of Han Chinese men in northwest China. The features and ear length of Mongolian young college students are similar to that of the southern Han nationality at the age of 20. Male physiognomic ear of Han nationality in Tunpu, Guizhou province is longer in this study (20-22 years old). Both male and female Mongolian college students have longer ears than those in Northwestern India. Caucasian male appearance ear is longer than those in Mongolian young male college students' appearance ear.
