The impact of body mass index on craniofacial parameters

Abstract

The purpose of the study is to analyze BMI and the mean values of craniofacial parameters in the patients measured by directed anthropometry (PDAA) and by 3D scan (P3DAS). The aim of the study is to identify the most frequent localization of facial fat. The study sample was recruited from patients attending dental surgeries in Bratislava. Data were collected from November 2013 to February 2016. In the first subgroup patients were analyzed by directed anthropometry (PDAA) (n=65). In the second subgroup patients were analyzed from 3D scan (P3DAS) (n=35). The differences in mean values of craniofacial parameters between the P3DAS and the PDAA groups had no significant effect on the evaluation of nose breadth, mouth and lower-lip height in the BMI category (18.6–24.9kg/m2). We found an association between BMI values and craniofacial parameters. In two study groups with >25.0kg/m2 higher values were observed in nose breadth, bi-zygomatic breadth, total facial height, mouth breadth and morphologic face height than in the group with 18.6–24.9kg/m2. In the P3DAS the facial fat was most often localized in the bi-gonial breadth and in the PDAA in the bi-zygomatic breadth.
