Aesthetic evaluation of craniofacial architecture in 20 adults / 中华医学美学美容杂志

ABSTRACT

Objective To investigate the aesthetic relations and internal regularities in normal craniofacial stereoscopic architecture. Methods By means of computer aided three dimensional measurement and analysis, a study on morphological features and inter relations of the cranio orbitozygomatic maxilla structures of twenty youths with pretty facial appearance was carried out. Results There were remarkable differences between each craniofacial structure in different sexes, but the ratio indices that represented the inter-relations of different craniofacial structures were closely similar in both sexes. In the group of youths the asymmetry ratios between bilateral craniofacial structures were below 5 % , presenting the perfect symmetry feature. The asymmetry ratios and their standard deviations of the zygomas and angulus mandibulae were relatively large . The results suggested that these two characteristic parts which influence the whole appearance were easily changeable with different individuals. There were close co relations between coronal axis width and sagittal axis protrusion in main structures of craniofacial region. These relationships could sum up in linear regression equations. Conclusion There are internal aesthetic regularities of coordinative ratios and harmonious symmetry in normal three dimensional craniofacial architecture, which determines the pretty appearance of youths. These internal regularities and aesthetic principles should be considered in designing and performing craniofacial aesthetic plastic operation so as to get excellent surgical results.
