This study examined the need for standard summary statistics for use in determining facial tissue thickness.
Abstract
This study examined whether the current technique of measuring only one side of the face was sufficient for collecting tissue depth data for three-dimensional facial reconstructions. Using ultrasound technology, measurements were taken at 31 points on the faces of 50 First Nations Nova Scotian adults (males and females) aged 19-77 years old. Analyses revealed that when all ages, and males and females, were combined, only one point demonstrated a statistically significant change with age. When males and females were separated, three points showed significant differences with age in males and only one point showed significant differences with age in females. Overall, First Nations tended to have thicker facial soft tissue when compared to American White and American Black populations at the majority of points on the face. These differences emphasize the need for population specific facial soft tissue depth data. The analyses suggest that measuring only one side of the face is sufficient when collecting tissue depth data for First Nations Nova Scotian adults. (Published Abstract)
