| Outline of Final Research Achievements |
The purpose of this study was to quantitatively define the facial characteristics of patients with congenital anomalies by constructing a virtual face and comparing it to that of non-syndromic subjects. The congenital anomaly group composed of Turner syndrome patients and the control group composed of non-syndromic subjects. Three-dimensional photographs were acquired from both groups using a non-contact three dimensions digitizer. Homologous models were constructed from the three-dimensional photographs using a three-dimensional shape analysis software.
From the homologous model, virtual faces of the two groups were compared by the averaged face technique. It revealed that in the congenital anomaly group, more protrusion of the subnasale to the upper lip, lower height of the apex of nose, deeper mentolabial sulcus and more mandibular retrusion particularly mentum region.
