Context: The face is the most important aspect of human identification. It also functions as the centre of attraction and appearance. Aim: The aim of this study was to characterize the facial profiles of Bini using angular photogrammetric analyses. Materials and Methods: A total number of four hundred Bini volunteers between the age range 18 to 30 years comprising two hundred males and two hundred females were recruited for this study. The photographs were taken with the subject keeping their heads in natural head at a distance of 150 cm from the camera in a well illuminated room in candescent light. All photographs were exported to Adobe Photoshop CS 5 Extended. The angle studied were nasofacial, nasofrontal, nasolabial and nasomental angles. Statistical analysis was done by using program Statistical Package for Social Sciences (SPSS), version 16.0 (SPSS, Inc., Chicago, Illinois, USA). Comparisons were made of all the facial angles studied between males and females using the students' t-test. Results: There was statistically significant sexual dimorphism in three of the angles measured. The nasofrontal angle was significantly higher (P < 0.05) in females (133.80 ± 0.40) than in males (128.00 ± 0.60). The nasofacial angle was significantly higher (P < 0.05) in males (35.580 ± 0.0) than in females (34.30 ± 0.20). The nasomental angle was significantly higher (P < 0.05) in females (128.10 + 0.30) than in males (126.90 ± 0.40). There was no statistically significant difference (P > 0.05) between the nasolabial angle of the males (76.20 ± 0.80) and that of the females (75.90 ± 0.70). Conclusion: This study has shown as in most other populations that the angular variables in tissue profile are sexually dimorphic among the Bini.
