| Summary: | This research explores the relationships between the facial creases and the morphology
of the underlying skull for supplementary use during forensic facial reconstruction.
The correlation between skull morphology and the patterns of facial creases
was obtained using the three-dimensional (3D) skull surface scans from the William
Bass skeletal collection at the University of Tennessee, USA, which also provided
the related ante-mortem face photographs. Superimposition of the facial crease patterns
seen in a face photograph with the related skull image enabled the visual analysis
of the correlation between the crease and the skull morphology. Qualitative
analysis indicated that the infraorbital crease follows the outline of the orbit in 52%
of the subjects, while the nasolabial fold (NLF) relates to the canine fossa in 95%
of the subjects. The infraorbital crease and NLF were reconstructed in a blind study
using ten 3D surface scan skull models and related face photographs from the
Helmer collection available in the Centre for Anatomy and Human Identification,
the University of Dundee, UK. Correct prediction was obtained in six specimens
(60%). One inconclusive result was due to poor photograph quality and three
inaccurate results showed an overestimation of the NLF strength although the
location of the crease manifestation was correct. |
