Sažetak
AIM: To compare the soft tissue facial surfaces of a sample of Croatian, English and Welsh populations. SUBJECTS AND METHOD: Seventy three 73 Croatian (52% females, average age 23 years) ; 80 English (50% females, average age 16 years) ; and 50 Welsh (46% females, average age 16 years) Caucasian subjects. Facial shells were acquired using three-dimensional cameras in the natural head posture and with a neutral face expression. A total of 21 landmarks were identified on each shell and six average faces were produced for the three populations considering gender. The facial shells were divided into eight regions (forehead, right eye, left eye, right cheek, left cheek, nose, upper lip and philtrum, lower lip and chin) ; surface based comparisons explored regional differences. Landmark based comparisons explored differences between facial shapes in three spatial dimensions (nose, eyes and mouth width ; full face, nose, upper lip, and lower lip and chin height ; protrusion of forehead, eyes, nose, and chin). All comparisons were performed separately for male and female population groups using ANOVA at P < 0.05. RESULTS: The Croatian females had more protruded regions of the nose, upper lip and lower lip and chin, when compared to the English and Welsh females [concordance range 15-56.2% (at 0.5 mm tolerance)] ; their eyes and cheeks were retruded more compared to the English females (concordance range 38.5- 72.8%).The Croatian males had more protruded regions of the forehead, nose and lower lip and chin, as compared to the English and Welsh males (concordance range 33.9-58.6%) ; their eyes were more retruded, as compared to the Welsh males (concordance range 18.2-24.4%). The Croatian males and females had smaller mouth widths when compared to their English counterparts ; on average -5.45 mm in males, and -6.06 mm in females (P < 0.05). The Croatian females had narrower noses than the English females (–1.58 mm) and Welsh females (– 1.46 mm), while the Croatian males had wider noses than the English males (1 mm) and Welsh males (0.82 mm) (all P < 0.05). Nose height was smaller in the Croatian males and females as compared to their Welsh counterparts (–0.83 mm for both ; P < 0.05). CONCLUSIONS: There are identifiable measurable facial differences between Croatian, English and Welsh populations.
