Abstract

The purpose of this study is to determine the soft tissue thickness around the face using A-scan ultrasound, for incorporation into a 3D head model as a design tool for safety equipment and facial prostheses for patients following maxillofacial reconstruction. Using very high frequency A-scan ultrasound allows the superficial tissue to be measured on volunteers without risk. The investigation covers 112 points on half of the face, linked to 11 defined morphological zones. The zonal boundaries are based on previous research and are initially identified by palpation of the face. The thickness of the facial soft tissue varies greatly between individuals but the calculations of average and standard deviation coefficients reveal that the distribution of the features in the same zone of an individual fits within a normal range of variation. The measurements presented for the thickness of soft tissues at different parts of the face can also be recommended for specialists in craniofacial identification. The results of this study will be presented and indications of its application to FEA modeling outlined.
