Analysis Of Morphous Characteristics Of Facial Reconstruction And The Five Organs In Chinese South Five National Minorities Crowd

Objective: To observe analytical five national minority crowd image information of face facial features, for example, the facial type , the eyebrow type and the Eye - brow spacing etc, trying to seek out facial features in every nations ,and set up a relevant library, provide help to some facial-skull reconstruction cases.Methods: Take everyone's equal picture and X-ray photograph normal and lateral view. Surveying and analysis every national minority crowd's facial morphous with the definitive 19 indexes.Sample collection: According to the Chinese population distribution situation and the fifth of national population census data, pick out 100 healthy majority men and women in five south national minority which above 1million populations, Take everyone's equal picture and X-ray photograph normal and lateral view. To be ensured the data was reliable, that the samples must be from the minority of original districts.Surveying index: Because of the facial five sensory organs form indicate the person's facial feature. According to the unknown cranial bones forms, in many forensic facial reconvension cases, we can infer from their facial form features. I n this research, we determined 19 indexes, for example, hair style, facial form, eyebrow-type et al, to study the five minorities'five sensory orgens features. Choosing five easier to observe project such as cheekbone part , degree of nasion introcession among them , then observe the correlativity among bony five sensory organs and the facial fives. Finally, make tabulations and statistics for the obtained datas and information, with contrast and calculation, analyzing the existence difference whether or not between every national minority and two genders.statistical method: By The SAS System software, the derived data should be analyzed using X2 Test or Fisher Test.Results: There are cardinal principle resemblant facial morphologic character among the five national minority crowd, but the distinctions , to some extent, that the Miao Nationality women have a bigger ratio of circular face form, while the Bai ,Zhuang, Dai and Miao Nationality men have the square form greatly. The Miao Nationality crowd have the single eyelids more than half. While the Yi Nationality men and Zhuang nationality women's orbital bones are protruted manifestly. More over, the Yi and Bai nationality women have the extroversion forms of angle of mandible so much. Mostly, The bony five sensory organs and facial five sensory organs of the five national genders have a coincidence. This reflect the consistency and relation of correspondence between cranial morphous and morphological character.Conclusion: Analyzing the statistics dates and information comprehensively, not only are there many concomitance points about the facial morphous of the five nationality crowd, but have many differences. For example, the Bai nationality crow's ellipse facial form, while The medium zygomatic bone approaches the characteristic of the Han nationality crowd in south China mostly. More over, The Yi nationality crowd have the comparatively width mouth and little rima oculi. Finally, concluding the facial morphous features every nationality, analyze the reasons, we believe, except the geno-factor, these reflected effect of other factors which their living environment, customs and habits etc. On the other hand, there aren't obvious differences among the nationalities, and most of indexes between the bony five organs and facials are coincidence. As for Female proportion is bigger in the non-coincidence items, we believe, except the factors of pictures and X-ray photographs taken process had co-operated insufficiently by the subjects themselves, certernly, the difference of facial soft tissue thickness may be also one of the causes.
