CT scanning was performed while participants raised their head in an upright position while in a prone body posture. The positional relationships between the skull and head surface shape were analyzed by creating anatomically homologous shape models. Before modeling, skull shapes were simplified by concealing hollow structures of the skull using in-house software. Surficial tissue thickness (STT), represented by the distances between corresponding vertices of the simplified skull and head surface, was calculated for each individual, and averaged for each sex. Although the approximate head shapes of known individuals showed a relatively good resemblance in both the shape of the whole head and facial parts, some errors were identified, particularly in areas with thick surficial tissue. The results revealed sexual dimorphism of STT, with males exhibiting thinner surficial tissue at the cheek, and thicker tissue at the glabella, nose, mouth, and chin. Moreover, we created referential models for craniofacial superimposition from average models of the skull and head surface shape for each sex.</p></div>","PeriodicalId":45371,"journal":{"name":"Journal of Forensic Radiology and Imaging","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.jofri.2019.05.004","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45134895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
